The P-1000 can fabricate pipettes for use in intracellular recording, patch clamping,
transferring (ICSI, ES Cells), microinjection, aspiration, and microperfusion. Realizing the
full potential of this instrument is dependent on a complete understanding of the way it
implements the pulling process. To this end, we urge that this manual be read in its entirety.
To aid in understanding the function of the instrument, sample programs are already loaded
in memory (Programs 0 through 5, as discussed in subsequent material).
The Model P-1000 Flaming/Brown Micropipette Puller combines a proven pulling technology
with programmability to produce a very versatile instrument. The pulling mechanism is
derived from the Flaming/Brown series of pullers, which have demonstrated the ability to
pull a complete range of pipette profiles. Added to this mechanism is the ability to program
different pulling sequences; thus, allowing ease of use for pulling a variety of pipette types on
one device.
The P-1000 is a ‘velocity sensing’ puller. This patented feature allows the puller to indirectly
sense the viscosity of the glass, giving the P-1000 the ability to pull pipettes from all glasses
except quartz. Even difficult to pull formulations, such as aluminosilicate glasses, are
handled with relative ease.
Throughout this manual reference will be made to the size of the glass tubing used to pull
micropipettes. The convention used here for describing the outside diameter (O.D.) and
inside diameter (I.D.) is as follows: O.D. x I.D. These dimensions will always be given in
millimeters (mm). See our catalog or visit
capillaries available for purchase.
The P-1000 micropipette puller is designed for use with aluminosilicate, borosilicate or other
lower melting-point glass tubing or rod ranging from 0.6 to 3.0 mm in diameter. This
instrument does not pull quartz glass. Examples of the specific types and sizes of glass that
can be used with the P-1000 are listed in the Sutter Instrument Company catalogue that was
included with this instrument or can be viewed on Sutter Instrument’s web site at
www.sutter.com

to the glass. If the jaws are repositioned and/or the filament type
has been changed, make sure that the securing screws of the jaws
and filament clamp are again tightened. Failure to tighten these
screws can result in, poor current flow for scorching and
insufficient heat to melt the glass. Please refer to Systematic

While we realize that most new users of the P-1000 are anxious to start pulling useable
pipettes right away, we cannot over-state the importance of taking a few moments to review
the manual in order to understand how the puller works. Many a heating filament has been
destroyed with first use due to not taking the time to understand the relationship between
the programmable heat settings and the filament installed in the puller. If you absolutely
must use the puller before reading through the manual, the following instructions are
provided to help you get going and keep you from vaporizing your heating filament.

2. The filament heats up, the glass softens, and a weak pull draws the glass out until it
reaches the programmed velocity.
3. When the programmed velocity has been reached, the heat turns off, and the air turns on
to cool the filament and glass.
4. If TIME is greater than 0 (zero), the hard pull (if any) is executed after a short delay (less

The HEAT value required to melt your glass is based on the characteristics of the heating
filament that is installed and the OD/ID of glass you are using. The RAMP TEST allows you
to systematically establish or adjust program HEAT values as a function of the filament/glass
combination. This test should be run when using the puller for the first time, before writing
or editing a program, whenever you change glass or whenever you change the heating
filament. A HEAT setting equal to the RAMP value is the best first setting with which to
start.
The ramp value is associated and stored with the current program.
You can access the Ramp Test screen from the Menu screen or by touching the Ramp

1. When the above screen is displayed, press PULL to run the ramp test.
2. The puller increments the HEAT, and the filament, after 1-2 minutes, begins to get hot
and glows orange in color.
3. The puller bars begin to move apart once the HEAT is hot enough to soften the glass.
4. As the glass begins to soften, a certain velocity of the puller bars moving apart is
detected, at which point the heat turns off.
5. Once there is a small melt in the glass, the new ramp value will be displayed.
6. You can accept the ramp value (in which case the value gets installed into your program),
7. Accept the ramp value and use a heat-setting equal to, or within five (5) units of, the

run the RAMP run the RAMP
settings in the factory-installed programs are typically set at Ramp value. If your Ramp test
value differs from the factory Ramp value, adjust the HEAT in your programs to your Ramp
value.
Once you have adjusted the HEAT value relative to the Ramp value, pulling a pipette is very
straightforward. Try executing the factory installed programs with the sample glass to
become acquainted with the pulling process.
1. Load the glass into the puller as described previously in the FIRST TIME USE chapter.
2. Press and then , to open Program 0.
3. Inspect the parameter values displayed for Program 0. Program 0 should display the
factory-installed values listed on the enclosed program sheet. Adjust the HEAT setting to
your Ramp value.
4. Press the < PULL > button. The heating filament will turn on and the glass should
separate within 10 seconds. The display will then report the number of heating cycles and
the total time that the heat was turned on.
5. Loosen the clamping knobs and remove the pipettes from the puller bars.
Unless otherwise stated on your program sheet, Program 0 is factory pre-programmed to pull
a micropipette (tip diameter less than 0.1mm) from 1.0 x 0.5 mm borosilicate glass. It will
pull the pipette in one heating cycle. The time reported is very useful for developing
programs and will be discussed in the Parameter Adjustment section of this manual.
A feature of the P-1000 is its capability to loop through a program. This is demonstrated
using Program 1, which is a factory pre-installed one-line program “loop” (repeat and pull in
stages) to create a patch-type pipette with a short taper and 1-3µm tip. Press RESET to exit
Program 0, and then , to open Program 1. The display for Program 1 should read
similar to the following:
<PULL>. The heating filament should loop on and off
<PULL><PULL>
repeatedly. Once the glass has separated, the pull is complete, and the display should read
similar to the following:
Figure 3-27. Pull cycle report (multiple-loops).
After the heat turns on in line 01, the glass heats up and draws apart until it reaches a
VELOCITY of 30, at which point the heat turns off and the cooling air turns on. The puller is
“aware” of the fact that the glass has not separated yet, and will go back to line 1 of the
program and try again; in effect, it begins ‘looping’. It will continue to do so until the glass
separates. This looping capability is particularly useful for fabricating patch pipettes, which
require multiple heating cycles to form the characteristic stubby geometry.

There is always the possibility that the puller will be given a set of values that ‘stall’ its
operation. For example, the HEAT value has not been set high enough to melt the glass, thus
the glass cannot be pulled and no VELOCITY can be achieved. If it appears that a situation
of this type has arisen, press the STOP key. This action aborts program execution and allows
editing to take place. The safe-heat mode (turned on) should prevent this event from
occurring.
All programs entered into memory (maximum of 100) remain there even after the power is
turned off or the RESET switch is pressed. Nevertheless, it is strongly suggested that you
keep a written record of your programs in case of unexpected difficulties.

3.8.2.1 HEAT
The HEAT setting will affect the length and tip size of the pipette. In general, higher HEAT
settings tend to give longer and finer tips. For trough filaments, the recommended starting
HEAT value is the ramp test value plus 10%. For box filaments, the recommended starting
HEAT value is the ramp test value. The program listed above will typically have heat on for 5
to 8 seconds after the < PULL >
< PULL > button is pressed. If the time is longer than eight seconds,
< PULL >< PULL >
and you are trying to pull a fine micropipette, increase the HEAT in 5 unit increments until
the pull takes place in less than eight seconds. If the pull occurs in less than three seconds,
decrease the HEAT until the pull takes place in 4 to 8 seconds. For the best micropipette
reproducibility with the finest tips, you should select a HEAT value that melts the glass in 5
to 6 seconds. For microinjection needles you should select a HEAT value that melts the glass
in about 7 seconds or longer.
3.8.2.2 PULL Strength
Low values of PULL strength in the range of 40-75 will give larger tips appropriate for
injection needles, while settings between 120-250 give smaller tips appropriate for
micropipettes. The PULL strength can be set to any value desired with no danger of
damaging the instrument.
3.8.2.3 VELOCITY (Trip Point)
The VELOCITY value determines the point at which the heat is turned off. VELOCITY
reflects the speed at which the two carrier bars are moving during the weak pull. The lower
the VELOCITY value, the slower the speed of the bars when the trip point occurs. Although
VELOCITY can safely be set to any value from 1-255, all values over a maximal trip point
(about 150) will produce equivalent results. As the pull progresses, the speed of the carrier
bars, as measured by the velocity transducer, reaches a point where further increases in the
VELOCITY trip point will not change the time point at which the heat is turned off.
VELOCITY is typically set between 80 to 120 for micropipettes or 50-80 for microinjection
needles.
In a multiple cycle program, it is possible for the glass to separate before the trip velocity is
attained. Thus, the glass is subjected to heating as it separates. Such an occurrence can lead
to difficulties in forming tips as well as lack of reproducibility. If you are using a one-line,
looping program, try decreasing the VELOCITY a few units at a time. If your program is a
multi-line program, decrease the VELOCITY in the next to last line of the program.
Decreasing the VELOCITY will increase the amount of glass left in the last cycle of the
program, thus allowing the glass to attain the trip velocity before separating.
3.8.2.4 TIME Mode (Cooling)
The TIME parameter controls the length of time the cooling air is active (one unit of TIME is
equivalent to 1/2msec). In order to produce effective cooling, the air must be supplied to the
filament and glass during the time the tip is being formed. In order to guarantee that cooling
occurs in this time frame, the start of the hard pull is begun after a fixed delay of less than
50msec from the termination of the heating cycle and the activation of active cooling. In most
applications, the hard pull lasts several tens of milliseconds. Because of this fact, increasing
cooling TIME values beyond a certain range (typically between 150 to 200) will have no
effect. Values of TIME shorter than this same range will cool the glass less as the tip is being
formed and lead to a longer taper. However, once TIME values become too short (values in
the range 110 to 130) cooling becomes ineffective. The glass will not form a tip and instead
forms a wispy fiber. The very finest tips for a given PULL and HEAT will be formed at an air
setting of about 5 units higher than the lowest TIME value that forms a tip. Because of this
quite narrow working range of usable TIME values for making micropipettes, it is not
recommended to vary cooling, and therefore electrode tip length, by adjusting TIME.
Adjusting the cooling air pressure, or switching to the Delay

3.8.2.5 Delay Mode (Cooling)

be sufficient to produce short pipette tapers. This may even be true at increased PRESSURE
settings (i.e. >500). In this case, it is recommended that the Delay mode of active cooling be
used. The method for changing to the Delay mode are described under “Software Control
Functions” and a brief description of the two modes of cooling is given in “Programs.”
After switching to DELAY mode, one then has direct control over the delay between turning
the heating filament off and initiating of the hard pull. Because the cooling air is turned on
when the filament is turned off, increasing DELAY profoundly increases glass cooling before
and during the hard pull.
With a range of control over the degree of pipette cooling one can control the rapidity of
pipette taper. Longer DELAY values increase cooling and form a pipette with a more rapid
taper (shorter shank) while shorter DELAY values decrease cooling and form a pipette with a
more gradual taper (longer shank). Fortunately, cooling induced changes in pipette taper
generally occur with little effect on tip size. This is quite valuable as the resistance of pipettes
is a strong function of the length of the taper. By making a pipette with a sharper taper, one
can often decrease pipette resistance significantly without changing the size of the pipette
tip. Furthermore, the ability to control tip length is invaluable for experiments where long
tips are necessary for penetration into deep tissues or where short stiff tips are necessary for
adequate beveling.
Minimum and maximum useable values of DELAY can be expected; their exact values are
dependent on glass thickness and diameter. If DELAY is too short, the glass will not cool
sufficiently to form a tip and a long wispy fiber of glass will be formed. This minimum
DELAY value is typically 80 (less than 50ms of delay). At some maximal value of DELAY, the
glass may be cooled too much to separate during the hard pull. Under these conditions, the
puller will typically execute multiple cycles in order to separate the glass and the glass may
break at a large tip diameter. Maximum usable values of DELAY will be dependent on glass
dimensions but are expected to be near 200 (100ms of delay).
3.8.2.6 PRESSURE Adjustment
The pressure setting controls the pressure of the cooling air delivered to the filament. The
higher the pressure, the shorter the pipette taper will be. Because thin walled glass cools
more rapidly than thick walled glass, the recommended values are ≤ 300 for thin walled
tubing and 500 for thick walled or standard walled tubing. By varying PRESSURE around
these values, the user can control pipette tip length over a moderate range.
Note that increasing the pressure value to some higher number results in an immediate
change in the pressure. A decrease in the pressure value will result in a pressure change at
the time of the next pull. This delay in pressure change occurs because the system must first
be purged of the air that is pressurized at the higher level. This will only occur prior to the
execution of a program. Each time the < PULL >
< PULL > key is pressed the air solenoid is opened
< PULL >< PULL >
and air flows through the air jet until the pressure drops below the set value. The solenoid
then closes and the compressor will pump until the correct pressure is attained. This
pressurization routine is meant to fully cool the filament and assure that the pressure is
precisely set.
3.8.2.7 Filament Width
Further control over pipette tip length can be accomplished by varying filament width.
Longer tips can be formed by using wider filaments and conversely shorter tips can be
formed by using narrower filaments.
Micropipettes used for the electrophysiological recording technique of “patch clamping” are
generally characterized by short, stubby shanks and relatively large diameter tips (> 0.7
mm). Programs that can fabricate a pipette with these characteristics generally differ from
programs for micropipettes in three ways:
The trip velocity is lower.
The trip velocity is lower.
The trip velocity is lower. The trip velocity is lower.

The P-1000 can be used very effectively for this type of processing. The following general
information will familiarize you with the effect of adjusting each of the pull cycle parameters
in a typical patch pipette program. Following this general information are step-by-step
instructions intended to help you establish a stable program to pull patch type pipettes and
should be followed in the order described.
Consider the following sample patch program for 1.5 mm O.D. by 1.1 mm I.D. borosilicate
glass using a 2.5mm box filament:

TIMETIME
PRESSURE
PRESSUREPRESSURE
A program sequentially executes each line of code, then loops back to the start, and begins
again until the glass separates. A single line program such as this may execute 2 to 4 times
before the glass separates.
3.8.3.1 HEAT
The actual HEAT value used should be sufficiently high to allow the glass to melt in the first
cycle in 5 to 15 seconds. Using a higher HEAT that melts the glass in less than 5 seconds will
cause no problem in the first heating cycle, but may heat the glass so much in subsequent
heating cycles, that the air cooling will be less effective.
3.8.3.2 PULL Strength
A constant gravitational pull on the carrier bars can be felt when loading the glass. This pull
is usually adequate to form relatively small-tipped pipettes (0.5 mm). Eliminating the hard
pull from the program (PULL=0) is recommended for most pipettes. If smaller tips are
required, a moderate PULL (25-50) may be used in the last line of a multi-line program (see
below).
3.8.3.3 VELOCITY (Trip Point)
VELOCITY determines the point at which the heat is turned off. If the value is too high, the
glass will separate after the first or second heat cycle. As the VELOCITY is decreased, the
amount of glass drawn-out in a given cycle will also decrease, and more cycles will be
required to form a tip. The greater the number of cycles, the larger the tip and the shorter
the taper will be. However, too many cycles can lead to variability. In general, it is advisable
to keep the number of heating cycles to 5 or less.
3.8.3.4 TIME Mode (Cooling)
For patch pipette programs, it is advisable to keep the TIME between 200 and 250 to
maximize the cooling of the glass. Delay mode of active cooling is not used in patch pipette
fabrication.
By contrast, to micropipette pulling (see above), the TIME settings in the upper range of
available values can have a pronounced effect on glass cooling. This additional cooling is
effective due to the lack of a hard pull and the multiple cycle nature of the pulling process for
patch pipettes.
3.8.3.5 PRESSURE
As with micropipette fabrication, the recommended pressure setting when using thick walled
glass is 500 or greater. For thin walled glass, the recommended setting is 300.
Note that increasing the pressure value to some higher number results in an immediate
change in the pressure. A decrease in the pressure value will result in a pressure change at
the time of the next pull. This delay in pressure change occurs because the system must first
be purged of the air that is pressurized at the higher level. This will only occur prior to the

When pulling pipettes where the pull occurs in multiple stages (i.e., patch pipette programs),
the temperature of the jaws that hold the filament can range from 23°C to 85°C. This
variation in jaw temperature can sometimes create instability in the program and lead to
inconsistency in the tip size, taper length, and cone angle of the resulting pipette. To further
regulate the pulling conditions, the new Thermolock™ feature can be used to pre-heat and
maintain the jaw temperature at 70°C.
If the “mid-point velocity” for writing a stable patch pipette program (Pipette Cookbook, Pg.
30) has been previously established, the shift and rise in jaw temperature is less likely to
introduce variability. However, if a program remains unstable where the first few pipettes
pulled are not ideal and later pulls provide better electrodes, the Pre-Heat mode for
regulating the jaw temperature can make your program more stable and improve the
outcome of resulting pipettes.
To activate the Pre-Heat mode in
your program, press <MENU> and
then select the box to “Pre-Heat
Jaws 70°C”.
When using the Pre-Heat mode, air
flush durations before and after the
pull are increased to 10 sec.
A caution is displayed indicating
that the filament will light up and
pre-heat. This yellow message bar is
displayed when powering up and
entering a Pre-Heat program; when
waking from sleep; and when going
from a non-Pre-Heat program into a
Pre-Heat program.
During Sleep mode, the pre-heating
is suspended. Upon waking from
Sleep, the yellow message bar is
displayed.
The initial pre-heating of the jaws
will take a few minutes, during
which the jaw temperature is
continuously displayed.
The user can load the glass at any
time, but if the glass is loaded
before the jaws reach 70°C, the PreHeat mode might not function as
intended.
When the jaw temperature reaches
70°C, a green message bar is
displayed indicating that it is okay
to install the glass and pull a
pipette.
When the capillary glass is inserted,
even if the Pre-Heat temperature
has not been reached, the filament
heat is turned off to prevent the
glass from melting and/or sticking
to the filament.
If the jaw temperature is above 70°C
when <PULL> is pressed, the air
flush occurs, but the pull cycle is
delayed until the jaws cool down to
70°C.
If the jaw temperature has dropped
to 70°C after the air flush, the pull
cycle will begin immediately.
If a program is opened with the
glass already installed, the user is
requested to remove the glass to
allow the Pre-Heat to continue.
If the glass is inserted when the
display is in the Sleep mode, this
message is also displayed upon
waking from Sleep.

StepStep
Run a Ramp Test with the glass you intend to use for your particular application. Refer to
the manual if you need to review the Ramp Test procedure. When you know the Ramp value
(R), use it in the following program.
1. Program one line of code as follows:
2. PRESSURE
PRESSURE should be set to 500 for thick walled glass and 300 for thin walled glass.
3. Insert your glass and execute the above program. The program should “loop” a multiple
number of times (i.e. the same line will be repeatedly executed). The display will report
the number of loops at the end of the pull sequence. This “looping” is the key to forming
patch pipettes. For thin walled glass, 3 to 4 loops are typically all that is required. For
thick walled glass, 3 to 5 loops are typically required.
4. Increase the VELOCITY in 5 unit increments and pull a pipette after each adjustment.
Note the change in the number of loops and note the geometry of the pipette (viewed with
microscope). As the VELOCITY increases, the number of loops decreases.
5. Repeat step (3) only this time decrease the VELOCITY. As the VELOCITY decreases, the
number of loops increases.
6. By adjusting the VELOCITY as described, establish the number of loops required to
approximately form a pipette with the characteristics you desire. Set the VELOCITY
value in your program to the number that falls midway between the values required to
loop one more and one less times than the desired number. For example: let’s say that
when you are experimenting with VELOCITY values, you find that when the glass
separates after 3 loops, the resulting pipette looks pretty reasonable. Let Y be equal to the
VELOCITY value that results with the glass separating after 4 loops. Let Z be equal to
the VELOCITY value that results with the glass separating after 2 loops. Set your
program VELOCITY, to a value midway between Y and Z. This value will be a very stable
VELOCITY value and will provide you with the most reproducible results.
7. The one line program just established may be sufficient for your application. However,
changes made in a one-line program are amplified throughout the cycle, potentially
producing gross changes in the pipette. If you need to make fine adjustments to the
pipette geometry, then you should use a multi-line program. The multi-line program is
based on the one line program just established. It is developed as follows:
8. Write your one-line, looping program out into an equivalent multi-line program with the
number of lines equal to the number of loops.
For example, a one line, 4-loop program with the following values can be written:
Line

PULL VELOCITY

as follows:

9. Now, you can make adjustments to the last or next to last line to fine-tune the program
and the resulting pipette.
10. Recommended changes to fine tune the multi-line program:
For larger diameter tips Decrease HEAT in last line
For smaller diameter tips Increase or decrease VELOCITY in next to last
units, or increase/decrease VELOCITY in la
units, or add a small amount of PULL (10 to 20) to last line

3.9.1.1 HEAT
For 1.0mm O.D. tubing, if the pull takes longer than eight seconds and you are trying to pull
a fine micropipette, increase the HEAT. To do this in a methodical fashion, increase the
HEAT value in five unit increments, each time monitoring pull time until the pull takes
place in less than eight seconds.
If the pull occurs in less than three seconds after you start, decrease the HEAT value in a
similar fashion.
For 2mm O.D. tubing, the pull should occur between 15 and 25 seconds after the start. Make
corrections as outlined above for smaller tubing.
3.9.1.2 Pipette Position
The position of the glass within the filament will also affect the time it takes to pull a pipette.
When using a trough filament, the glass should be about 0.5mm above the bottom of the
filament and centered front to back. In the case of a box filament, the glass should be in the
center of the filament. Filament positioning is covered in the next section of this manual
“Heating Filaments”.

Regulating the Length and Tip Size of a Sharp PipetteRegulating the Length and Tip Size of a Sharp Pipette
3.9.2.1 HEAT
Higher HEAT settings will give longer and finer tips. A HEAT value equal to the Ramp Test
value plus 15 will generally give a very fine tip.
It should be noted that at high HEAT settings (filament white-hot) the filament life is greatly
reduced. It is suggested that a setting equal to the ramp value plus 15 is used initially and
electrode length is controlled by air pressure adjustments. If this is insufficient, filament
width can be varied.
3.9.2.2 Filament Width
Filaments narrower than 2mm cannot form as fine a tip as the wider filaments. The tip size
will decrease with increasing filament width until a width of 3mm is reached. Increasing the
filament width beyond 3mm will produce longer tips with a more gradual taper (which may
penetrate better in some cases). The tip, however, will not be any smaller.
Tips of 1-2µm can be formed using a 1.5mm filament with low filament temperatures and
weak PULL strengths.
3.9.2.3 Air Flow
In general, electrodes will not be formed if the air pressure is set too high. It is thus
recommended that the front panel pressure adjustment be set to standardized values of 500
for thick walled glass and 300 for thin walled tubing. However, as outlined above, under
Micropipette/microinjection needle fabrication
Micropipette/microinjection needle fabrication, the length of pipette tips can be controlled by

varying air pressure. Furthermore, when making patch pipettes, if increasing TIME to its
maximal setting of 255 does not provide enough cooling to produce tips with a short enough
taper, then increasing pressure above the standard values may be warranted.
3.9.2.4 DELAY Mode of Active Cooling
As discussed previously in this manual, switching from the TIME to the DELAY mode of
active cooling may provide more precise and a wider range of control over the length (or
taper) of a sharp pipette tip. The delay mode is often employed when using thick walled glass
or for programs designed for the fabrication of pronuclear injection needles.

3.10 Fire Polishing
Fire Polishing
3.103.10
Fire Polishing Fire Polishing
The P-1000 micropipette puller allows you to perform pseudo fire polishing of pipette tips but
does not have a provision for visualizing the pipette tip during the heating process. The
extent of the heating required to attain the desired degree of polishing must be empirically
established.
What distinguishes a program for polishing from other programs used to pull pipettes is the
use of a Velocity value of 0. To program the instrument for the fire-polishing mode, try
entering a program as follows:
HEAT
HEAT PULL
HEATHEAT
Ramp value
PULL VELOCITY
PULLPULL
0 0 250
VELOCITY
VELOCITYVELOCITY
TIME
TIME
TIMETIME
Pressure does not matter because the air supply is never activated in this mode.
When executed, this program will behave as follows: the Heat will turn on for the duration
set by Time. Each Time unit is equivalent to 10 msec. Therefore, in the above program, the
Heat will turn on for 2.5 seconds.
The procedure for polishing is as follows:
1. Pull a pair of pipettes with the desired pulling program. After the pipettes have been
pulled, keep them clamped in the puller bars.
2. Reset the puller and select your polishing program (as above).
3. Manually push the puller bar (with the installed pipette) back towards the filament, or
use the Fire Polish Spacer block described next. Try positioning the tip of the pipette just
inside the edge of the filament.
4. Press Pull and the filament will heat up for 2.5 seconds, exerting a polish on the end of
the pipette.
How much polishing occurs will be a function of the Heat value and the duration of that Heat
as determined by the Time value. You may need to execute the program multiple times to
achieve an appropriate polish. You will need to experimentally establish how much Heat and
how much Time is necessary for the degree of polishing you require.
The most difficult part of this procedure is manually positioning each pipette back into the
filament at the same relative position each time. The Fire Polishing Spacer allows you to
consistently reposition the pipette within the filament. The T-shaped aluminum Spacer has
an adjustable setscrew protruding from it.
Figure 3-28. Side view of fire polishing spacer.
The Spacer/screw combination fits into the slot in the puller bar and fixes the puller bar
position. You adjust the screw position to set the position of the puller bar (and thus the
pipette tip). The more extended the screw is, the closer the pipette tip will be to the heating
filament.
When you have finished polishing the pipette, remove the Spacer from the puller bar.

The pipette programs that you ultimately develop will largely depend on the type of heating
filament installed in the puller and the glass that you use. Depending on the research
application, there may be filament-glass combinations that are more optimal than the one in
the current puller setup. After reading through the following material, if you have questions
about which filament to use for your application, contact our technical support staff.
Figure 3-30. End view of trough filament and glass.
The trough filament is a general-purpose filament. It is recommended for standard or thin
wall glasses used for patch pipette fabrication, sharp electrodes with short tapers, and some
types of microinjection needles. The geometry of the trough allows the filament to cool
rapidly during the cooling phase of the pulling process.
3.11.2.1 Positioning
When using the trough filaments, the glass tubing should be positioned just above the bottom
of the filament (approx. 0.5mm), and centered between the two sides (Figure
Figure 3333----30
FigureFigure
30). This
3030
position can be adjusted by using the two eccentric chrome screws located on the aluminum
angle piece that holds the filament assembly (A and B in Figure

Figure 1111----3333). First loosen the two
FigureFigure

FigureFigure
the Filament Replacement section of the Maintenance Chapter for a full description of this
adjustment.
3.11.2.2 Geometry
The geometry of the trough filament is an important factor for proper heat application to the
glass. Replacement trough filaments should have a profile similar to that illustrated in
Figure
Figure 3333----30
FigureFigure
30, where the distance between the top corners (distance A) is approximately 2/3 the
3030
length of the bottom of the filament. This geometry will provide improved heat distribution
to the top of the glass tubing. When replacing a filament, check the new filament geometry. If
it differs appreciably from the ideal, you can easily modify it by grasping the bottom corners
with non-serrated forceps and gently pushing on the horizontal ‘wings’.
The trough filament you select depends upon the length of the taper that you want. Wider
filaments for special purposes are available upon request.
Another type of filament that can be used is the box type heater filament. The box filament
heats the glass in a more symmetrical fashion than trough filaments, so that the pipettes
produced tend to be more straight and concentric than those pulled with a trough filament. It
delivers more heat to the glass resulting in faster heating without the necessity of increasing
the temperature of the filament.

The box filament has two primary limitations.
First, it requires more current to heat to a given temperature than the same size
trough filament. Thus, it is possible to use wider trough filaments without exceeding
the maximum current capacity of the puller.
Second, the box configuration reduces the cooling effect of the air jet. For this reason
the box filament is sometimes not recommended when very short pipettes are to be
formed.
3.11.3.1 Positioning
When using a box filament, the glass tubing should be centered vertically and horizontally
(Figure
Figure 3333----31
FigureFigure
31).

This position can be adjusted as described above for the trough filament. See Figure

the Filament Replacement section of the Maintenance section for a full description of this
adjustment.
3.11.3.2 Geometry
The box size you select should be approximately 1.0 to 1.5mm larger than the outside
diameter of the glass you are using. The width of the filament will depend on the research
application. A good general-purpose box filament is the 2.5mm wide, 2.5mm high and 2.5mm
deep filament (FB255B
FB255B). Special box filaments made to accommodate larger diameter glass or

special pulling applications are available upon request.
To maintain the P-1000 in optimal condition the vinyl dust cover that is shipped with the P1000 should be used whenever the unit is turned off to protect the puller from dust and
spills.
Occasionally clean the exterior and the base plate of the unit by wiping them with a dry cloth
to remove dust and fine pieces of glass. Avoid contact with the filament.

The correct position of the glass capillary in each of the two filament types is shown above in
the Heating Filament section. This positioning is critical in achieving the desired pipette tip
size and shape; it will also almost certainly require adjustment after replacing a filament. To
make this adjustment:
1. Carefully slide the glass to be used along the V-groove in the puller bar, and see where it
is positioned relative to the filament.
2. Locate the aluminum angle plate to the right of the filament assembly and behind the

This program is only being used to test pipette length. Pull a pair of pipettes. Remove the
pipettes from the carrier bars and hold them side by side as shown in the figure below. If the
shanks of the pipettes vary in length, this is an indication that the filament is not centered
left to right relative to the air jet, thus one pipette is “seeing” more cooling than the other.
Loosen the filament clamping screws and move the filament very slightly towards the side
that produced the shorter pipette. Then tighten up the clamps and try another pull. You may
have to go through several iterations before you get it centered properly.
Right-side pipette is longer than the one on the
left. Shift heating filament to the left a small
amount (move filament towards shortest pipette).

pulleys, be certain that the filament and air jet are correctly positioned before proceeding.
The pulley adjustment is made by moving one or both of the pulleys to equalize the tension
on the two cables. There are two sets of stops in the system; the stops in the carrier slots

without significant tension on the cables. If there is too much tension, the initial pull will
depend on how tightly you hold the finger stops when the glass is clamped in the carriers. If
this happens, the electrodes will not be consistent from pull to pull.

Regeneration of Drierite GranulesRegeneration of Drierite Granules
The Indicating Drierite found in the canister at the right rear corner of the base plate on the
P-1000 is a desiccant made of calcium sulfate (97%) and cobalt chloride (3%). This material is
used to remove water vapor from the air-cooling supply system. The drierite granules become
pink as they absorb moisture, eventually requiring that they be “regenerated” (dried).
Before proceeding, make sure the puller is off and unplug the power cord. To remove the
canister from the -, first remove the plastic puller cover by loosening the three screws that
hold it down. Next, slide the input (left) and output (right) air tubes off their white plastic
connectors on the canister. Finally, the two black plastic clamps that secure the canister to
the baseplate can be released by forcing one half of the connector out of the other half at the
point where they meet. The canister can be removed.
Unscrew the aluminum end cap, being careful not to loose the black rubber-sealing ring that
forms the airtight seal under the cap. With the cap off, the spring, its associated aluminum
keeper and the first filter can be removed exposing the Drierite. The exhausted granules can
then be removed from the canister. DO NOT UNDER ANY CIRCUMSTANCE REMOVE

a tray and heated for one hour at about 200 degrees Celsius. The granules should then be
cooled in a tight container before refilling the plastic canister. Filters should also be pre-dried
at 100°C for about 30 minutes before assembly. Drierite is not toxic and can be handled with
few precautions. For more detailed safety information, please refer to the enclosed
MATERIAL SAFETY DATA SHEET.
The Drierite, filters, and keepers are installed in the canister in the order they were removed.
First, install a filter against the keeper that was left in the canister. If this keeper was
removed, slide it back in first and make sure that it lays flat against the plastic shoulders in
the far end of the canister. With the far keeper and filter in place, pour in the regenerated
Drierite. Next, insert the second filter followed by the keeper attached to the spring. Finally,
lay the rubber seal in the cover and screw on the cover being careful to keep the seal laid out
flat as you tighten. There is no need to over tighten the cover, but it should be possible to
hear and feel it seating firmly against the rubber seal.
Reinstall the canister on the puller baseplate with its cover to the left and the air tube
connections to the front. The black plastic hold-downs slide inside one another and are
pushed tight by hand to firmly hold the canister in place. At this

Problem: What type of glass should be used?
5.1.15.1.1
Problem: What type of glass should be used?Problem: What type of glass should be used?
The type of glass and the wall ratio I.D. (inside diameter) to O.D. (outside diameter) are two
of the most important variables in controlling tip size. For example, using borosilicate glass
with an O.D. of 1.0mm and an I.D. of 0.50mm will give tips of 0.06 to 0.07mm as
demonstrated in Program 0. Using the same settings, borosilicate glass 1.0mm O.D. and
0.78mm I.D. will form tips of 0.1 to 0.12mm. Aluminosilicate glass with an O.D. of 1.0mm
and an I.D. of 0.58mm will form tips of 0.03 to 0.04mm again with the same settings.
In general the thicker the wall in relation to the O.D. of the glass the finer the tip will be,
and the thinner the wall the larger the tip will be. Thin wall glass will give the best results in
most experiments as it will have the largest pore for a given tip size. This means it will have
a lower resistance and will allow for easier injection of solutions. However, in many cases
with small cells the thin wall glass will not form tips fine enough to obtain good penetrations.
In this case, heavier wall glass must be used.

The first point to note is that there is very little correlation between tip size and electrode
resistance. Most of the resistance of a microelectrode is in the shank of the electrode behind
the tip. Electrode tips that are 0.1 mm in diameter can vary in resistance from 20MW to
1000MW depending on the length of the electrode and what is used for the filling solution. If
the same solution is used then resistance may give an indication of how well the electrode
will penetrate a cell as the electrode with the higher resistance will probably have a longer
shank and a smaller cone angle at the tip. This combination will aid in the penetration of
cells where the cell is not a surface cell.

Problem: How can tips be made even smaller?
5.1.35.1.3
Problem: How can tips be made even smaller? Problem: How can tips be made even smaller?
1. The first thing to try in most cases is to increase the HEAT value. This will generally
decrease the tip size but it will also give a longer shank. If the higher resistance is not a
problem, this is generally the best solution. Continuing to increase the HEAT, however, is
not the final answer as too high a HEAT can lead to larger tips. In general, with 1.0mm
O.D.X 0.5mm I.D. borosilicate glass the finest tips will be formed when the glass pulls in
5 to 7 seconds after starting the pull.
2. If the electrode is now too long and results in a resistance too high to pass the necessary
current, then the next step is to increase the pull strength. In general, a pull strength of
125 will give tips of less then 0.1mm. Increasing the pull to 250 will reduce tip size about
5-10%. We recommend a pull of about 150 in most cases.
resistance
resistance resistance
3. The last major variable to adjust is the amount of cooling of the glass during the pull. If
in the case of 1.0mm O.D. X 0.5mm I.D. borosilicate glass the pull takes place in 5-7
seconds, the tip size will not change with a change in the cooling air. The only change will
be in the length of the shank. If however the HEAT is such that the pull takes place in
more then 8 seconds, decreasing the cooling may somewhat decrease the tip size. Cooling
can be most effectively decreased in the P-1000 by decreasing air pressure, however a
decreasing TIME may also be useful.

1. The first thing to try is to reduce the HEAT. Try dropping the HEAT 5 units at a time to
see if this will increase the size of the tips.
2. If this does not work, increase the pressure in units of 50. The PULL should generally be
set to 0 when pulling large tipped (1-10 mm) pipettes.

This can happen when a pipette is formed in two or more loops. If the pipette is formed in
three loops in one case and then on the next pull it forms in four loops the tips will not be the
same. Adding one unit in the VELOCITY value will in most cases cause the pipette to be
formed in three loops or subtracting 1 unit should cause the pipette to form in 4 loops. It is
always good technique when a program is developed that produces a desired pipette, to try
increasing and decreasing the VELOCITY value to be sure that you are in a stable region.
The best procedure in developing a very reliable pipette program is to change the VELOCITY
value both up and down until the number of cycles to pull the pipette changes. Then pick a
value halfway between for the final VELOCITY value.

Try a program in which the first two lines of the program have a PULL value of 0, a
VELOCITY value of 10 to 30, a TIME setting of 200 and use the ramp value for the HEAT
(box filament). The third line should have the same HEAT value, a PULL value of 150, a
VELOCITY of 30 and the TIME should be between 0 to 50 depending on the tip needed
(values may vary depending on glass characteristics).
The idea behind this program is to reduce the size of the glass on the first two cycles and
then on the third cycle we give a hard pull with the air turned off. Normally if the air is
turned off a long wisp will result, but since we have greatly reduced the size of the glass and
with a very hard pull the glass will tend to separate when it is about 1mm in diameter.

This problem occurs most often when using the trough filament. Going to a box type of
filament will produce straighter pipettes. The pipette’s bend has no effect on its tip and
should not cause problems unless when penetrating quite deeply into tissue and aiming at a
certain site. Then the bend may lead the pipette to the wrong area. The box filament is not a
complete improvement on the trough filament as the airflow is much less effective with the
box filament, and you give up much of the length control that the cooling air gives with the
trough filament.

1. In most cases, this is due to one or both of the cables to the pipette carriers being set up
too tight. If the cable is adjusted so that the carrier can’t come against the stop in the slot
in the center of the pipette carrier, then the initial pull tension will depend on how hard
the carriers are squeezed together when the glass clamps are tightened. To adjust, see the
pulley adjustment section.
2. A second possible cause of this problem is dirt on the carrier bars or bearings. In this
case, clean the carriers and bearings with a lint free tissue or cloth.
3. If the problem persists, then run the ramp test several times. If possible, use one long
piece of glass and move the glass over after each ramp test. If the ramp values are +/- 4
units or less the problem may be with the glass. If the values are greater than +/- 4 units
call Sutter Instruments.

Figure 5-1. Starting Diagnostics from the Main Menu screen.
The Diagnostics screen provides the means by which each P-1000’s hardware
subsystem can be operated and tested indipendently.
Figure 5-2. Diagnostics screen.
The Diagnostics screen can be invoked at any time should test and diagnostics be
desired on any of the four hardware subsystems listed in the menu. These same
diagnostics can be useful in troubleshooting problems while in telephone contact with
Sutter Instrument Company Tech Support. The rest of this section covers the use of
the Air, Heat, Pull, and Velocity Sensor subsystem diagnostics.
The Air Pressure System diagnostics menu shown in the following figure lists several
diagnostic tests any one of which can be selected for specific tests.
Figure 5-3. Air pressure system diagnostics screen.
5.3.1.1 Air Pressure Amount (“Pressure dialed in”)
The amount of air pressure is shown in the “Pressure dialed in” field. This field is
always highlighted so that differrent pressures can be selected using the front-panel
Dial. Once the field contains the desired pressure value for testing, press ENTER to
set that value.
5.3.1.2 Air Pressure Transducer Reading
The associated non-editable numeric field contains the pressure value from the
transducer after a test has been made.
5.3.1.3 Air Pump Test (“Run the pump unregulated 1 sec.”)
Run this test to verify that the air pump is working. While the test is running, the air
pump will be audible, and if the test is successful, the pressure transducer reading
will rise.

5.3.1.4 Automatic Pressure On/Off
The Automatic Pressure test is a test of the air pump and the regulating circuitry.
This test also checks for air leakage from the system.
This test verifies that the air valve opens correctly causing the displayed Pressure
Transducer value to drop.
5.3.1.6 Test for air leaks
The air leak test consists of raising the pressure to 500 and then turning off the
pump for 10 seconds while testing for a drop in pressure. During the 10 seconds that
the pump is turned off, an error will be reported if the pressure drops more than 6
units.
5.3.1.7 Trace and correct leaks
This sequence of tests facilitates the detection and location of leaks in the air system,
and provides guidelines on how to repair the leaks. Follow the instructions on the
screen.

The diagnostics for the heating system is reached by the pressing Heat in the main
diagnostics screen, whereupon the screen shown in the following figure is displayed.
To start the heat diagnostics, press Enter. The heating system is tested at a value of
200 for 10 seconds. The Heat current is controlled by two field effect transistors
(FETs). FET A and FET B currents should both be equal to the Heat value of 200,
within a few units. If they are unequal, there is circuit board fault. If they are both
lower than the Heat setting, the Heat current is low. This can be due to a circuit
board fault, but more often indicates a broken heat filament.
Fault conditions are reported in red after the test, as shown in the following figure.
Figure 5-5. Heat system diagnostics error reporting.
The temperatures of the Puller Jaw and the internal Heatsink are continuously
displayed. If Jaw Temperature exceeds the maximum allowed, the Heat will be
automatically turned off to avoid damage to the nylon mounting block. If the internal
heatsink temperature exceeds its maximum, a RESET will occur.

Velocity DiagnosticsVelocity Diagnostics
The velocity diagnostics screen is reached by pressing “Velocity” in the main
diagnostics screen. The Velocity diagnostics screen is shown in the following figure.
In this screen, you can check the sensitivity of the velocity sensor and the operation
of the optical sensor that detects when the glass has separated.
The Velocity value is always highlighted for editing with the Dial. Press ENTER to
set.
When the Puller Bars move apart, a signal is generated that is dependent on the
velocity of separation.
The Velocity setting is the threshold value at which the Trip occurs, as indicated on
the screen.
A difference in sensitivity to movement at higher or lower settings can be noticed.
The Background Velocity serves to calibrate the true zero reading. It is typically 1-2
units. A higher number can indicate an electronic fault.
This calibration is done automatically at each pull.
The “Puller bar end of travel sensor” shows “Tripped” when the bars are apart and
“Not Tripped” when they are fully together.
Adjust your Program Heat values to reflect the change in Ramp value.
The touchscreen can drift out of alignment with the display over time. If ever the
screen is so badly misaligned that the Touchscreen is not usable, recovery is still
possible. Press RESET. When the Home Screen displays press PULL and the
calibration routine will run.

In the event that the controller fails to power up when the power switch is turned on, check
the line power fuse to see if it has blown. The fuse is located in the fuse holder on the power
entry module on the back of the controller. To remove the fuse holder first unplug the power
cord from the power entry module. This will reveal a slot just under the edge of the fuse
holder. Use a screwdriver to pry the holder straight out of the power entry module.

The fuse that is readily visible in the fuse holder when you take it out is the one that is
“active” when the holder is installed. A spare fuse is also stored within the fuse holder.
Replace the active fuse with the spare and re-install the fuse holder and power cord. If the
controller fails to power up with the new fuse installed, call Sutter Instrument technical
