1  INTRODUCTION

PIPETMAN L is an air displacement pipette and is used with
disposable tips. To answer the current needs of intensive use
of pipettes, and still being conform to Gilson brand qualities,
improvements have been implemented to our mechanical series:

 Light and comfortable body, both for right and left handed.
 All forces necessary to pipetting task dramatically decreased*.
 Lockable volume, except for the Fixed models.
 2D code for traceability.
 Name tag.
 For the single variable volume models, you have the choice

for an ejector plastic or a stainless steel ejector.

* Implementation of new features to improve dramatically pipetting
comfort has no impact on the legendary robustness, accuracy and
precision of PIPETMAN.

Eight single channel models cover a volume range from 0.2 µL
to 10 mL.

Fixed models cover a volume range from 1 µL to 5000 µL with
15 models.

Eight multichannel models cover a volume range from 0.5 µL
to 300 µL.

4  SETTING THE VOLUME  Only for Single and Multi­channel models

The volume of liquid to be aspirated is set using the volumeter. The
dials are colored either black or red to indicate the position of the
decimal point, depending on the model (see examples).

Lock System

For additional safety, the volume selected is lockable.

With the left or right thumb, unlock the thumbwheel by push­ing it up.

The volume is set by turning the thumbwheel.
The thumbwheel may be turned using only one hand to slowly

reach the required setting.
Push down the thumbwheel; the new volume selected is locked.

To obtain maximum accuracy when setting the volume, proceed
as follows:

 when decreasing the volume setting, slowly reach the required

setting, making sure not to overshoot the mark.

 when increasing the volume setting, pass the required value by

1/3 of a turn and then slowly decrease to reach the volume, mak­ing sure not to overshoot the mark.

5  USER ADJUSTMENTS  Only for Fixed models

PIPETMAN L Fixed is factory calibrated using distilled water and
very high precision balances. The nominal value of the PIPETMAN L
Fixed may be slightly adjusted to compensate for liquids of dierent
density or viscosity.

To accomodate for density or viscosity, an adjustment with one full
turn of the calibration key in either direction equals:

± 0.05 µL (models F1L to F2L)
± 0.2 µL (models F5L to F10L)
± 0.5 µL (models F20L to F25L)
± 2.0 µL (models F50L to F100L)
± 5.1 µL (models F200L to F250L)
± 20 µL (models F300L to F1000L)
102 µL (model F5000L).

The cover is graduated in tenths of the key revolution (letters A, B,... J) and is read
from left to right. Each small graduation mark represents 0.25 of the distance
between each letter.

To adjust the volume setting to compensate for a specic density or
viscosity, engage the two hooks of the spanner tool inside the two
small holes on the top of the body, then turn the key slowly:

 Clockwise to decrease the volume ; making sure not to overshoot

the mark.

 Counterclockwise to increase the volume; pass the required

value by 1/4 turn, then slowly decrease the volume to reach the
required setting.

Example: When using a PIPETMAN L Fixed100 to aspirate a particularly viscous solu­tion, you may determine gravimetrically that the volume delivered is 98.8 µL, and the
display reads “H”. Therefore, you wish to increase the volume dispensed by 1.2 µL. As the
interval between each letter on the calibration display represents 0.2 µL for the F100L
(1/10 of 2 µL), the calibration tool must be turned 3 units until the display reads “B”.

It is possible to alter the volume by more than one full turn in the counter­clockwise direction. In this case, remember to readjust the same number
of turns when it is necessary to return to the original setting.

Check the new volume gravimetrically. If the volumes delivered are still
not suciently close to the desired value, make another slight adjust­ment in the relevant direction. Be sure to change tips between volume

setting adjustments and to pre-rinse each new tip.

When the PIPETMAN Fixed is readjusted to compensate for a particular
solution, the nature of the liquid can be noted on the labels inserted in
the slot under the counter.

Liquids of high density, vapor pressure,
or viscosity are best pipetted by the
MICROMAN positive displacement pipette.

6  PIPETTING

For optimum performance, use of PIPETMAN DIAMOND Tips with your PIPETMAN L is strongly
recommended. These tips, made from pure polypropylene have the Gilson logo engraved on their
collar, ensuring that you have a genuine Gilson product. Plastic tips are for a single application –
they must not be cleaned for reuse.

PIPETMAN L can also be used with the main tip brands.

Fitting the tips - only for Single and Fixed models

To t a new PIPETMAN DIAMOND Tip, push the tip-holder into the tip using a slight twisting mo­tion to ensure a firm, airtight seal.

Fitting the tips - only for Multichannel models

PIPETMAN DIAMOND Tip: TIPACK™ and TOWERPACK™
– ROCKY RACK™

PIPETMAN DIAMOND Tips are best fitted from the
patented ROCKY RACK available only in our TIPACKS
and TOWERPACKS.

ROCKY RACK is the dome-shaped part of the pack
that contains the tips. ROCKY RACK makes it easy to
securely fit the tips to a multichannel pipette, ensuring
an airtight seal on all channels without the need to use
undue pressure or to touch the tips.

Ejector spacer for PIPETMAN L Multichannel 10 µL

Pre-rinse the tips

Some liquids (e.g. protein-containing solutions and organic
solvents) can leave a lm of liquid on the inside wall of the tip
; pre-rinse the tip to minimize any errors that may be related
to this phenomenon.

Pre-rinsing consists of aspirating the rst volume of liquid and
then dispensing it to waste. Tips will not fall o nor will they
have to be manually positioned.

Subsequent volumes that you pipette will have levels of ac­curacy and precision within specications.

Aspirate

Press the push-button to the first stop (this corresponds
to the set volume of liquid).

Hold the pipette vertically and immerse the tip in the liquid
(see immersion depth table, page 7). Release the push­button slowly and smoothly (to top position) to aspirate
the set volume of liquid. Wait one second (time depends
on model, see table page 7); then withdraw the pipette-tip
from the liquid. You may wipe any droplets away from the
outside of the tip using a medical wipe, however if you do
so take care to avoid touching the tip’s orifice.

For the Multichannel models, use a Gilson reagent reservoir.

Dispense

Place the end of the tip against the inside wall of the recipient
vessel (at an angle of 10° to 40°).

Press the push-button slowly and smoothly to the rst stop.
Wait for at least a second, then press the push-button to

the second stop to expel any residual liquid from the tip.

* Thanks to the new ejector spacer, you can adapt a D10
tip (see below).

7  GENERAL GUIDELINES FOR GOOD PIPETTING

Make sure that you operate the push-button slowly and smoothly.
When aspirating, keep the tip at a constant depth below the surface of the

liquid (refer to the table).
Change the tip before aspirating a dierent liquid, sample, or reagent.
Change the tip if a droplet remains at the end of the tip from the previous

pipetting operation.
Each new tip should be pre-rinsed with the liquid to be pipetted.
Liquid should never enter the tip-holder; to prevent this:

- press and release the push-button slowly and smoothly,

- never turn the pipette upside down,

- never lay the pipette on its side when there is liquid in the tip.

If you use the same tip with a higher volume, pre-rinse the tip.
For volatile solvents you should saturate the air-cushion of your pipette

by aspirating and dispensing the solvent repeatedly before aspirating the
sample.

When the pipetted liquid is not at room temperature, pre-rinse the tip
several times before use.

You may remove the tip-ejector (see Chapter 12 - Maintenance) to aspirate
from very narrow tubes.

After pipetting acids or other corrosive liquids that emit vapors, remove
the tip-ejector, the tip-holder, rinse, dry and lubricate the piston (

see

Chapter 12 - Maintenance

). For the model P1000L, by using a specic tip
holder equipped with a lter, you can increase the lifetime of the piston
(see Chapter 8 - Accessories).

Do not pipette liquids having temperatures above 70 °C or below 4 °C.
The pipette can be used between + 4 °C and + 40 °C but the specifications
may vary according to the temperature (refer to the ISO 8655-2 standard for
conditions of use).

8  ACCESSORIES

To make pipetting more comfortable and more secure, Gilson has developed
several accessories:

To avoid the possibility of
liquid running back into the
pipette, store the pipette
vertically.

Universal Multichannel Stand
is for Multichannel only.

To identify or personalize your
pipette, COLORIS™ clips are
available.

To protect the piston when
pipetting corrosive liquids,
you can use a specific tip
holder and lter for the model
P1000L.

12A  MAINTENANCE FOR THE SINGLE AND FIXED MODELS ONLY

Routine maintenance will help keep your pipette in good condition, ensuring a
continued high level of performance.

Maintenance is limited to:

 Cleaning or decontamination (see Chapter 13 - Cleaning and Decontamination)
 Replacing spare parts
 Greasing the piston assembly.

PIPETMAN P2L and P10L, F1L, F2L, F5L and F10L should not be disassembled,
so you may only replace the push-button, tip-ejector, dual position tip-ejector and
its adapter. With these pipettes if the tip-holder is damaged, the piston may also
be damaged.

After replacing any parts you
should verify the performance
of your pipette following the
verification procedure available

Servicing the Piston Assembly

You may remove the piston assembly for cleaning purposes
only. If the piston assembly is changed, the pipette must be
adjusted and calibrated in a Gilson authorized Service Center.
As the models P2L and P10L, F1L, F2L, F5L and F10L contain
miniaturized parts, it is best not to disassemble these pipettes
yourself.

The piston assembly must not
be autoclaved.

Remove the tip-ejector (see above).
Unscrew the connecting nut by turn-

ing it

clockwise.

Carefully separate the lower and up­per parts.

Remove the piston assembly, O-ring
and seal.

Leave exposed the piston, clean it with isopropanol or
ethanol and lubricate lightly.

For P20L, P100L, P200L, F20L, F25L, F50L, F100L, F200L,
F250L: lubricate only the useful part of the piston (20 ±5

mm length) and the O-ring.
For P1000L, F300L, F400L, F500L and F1000L: lubricate

the piston.
For P5000L, P10mlL and F5000L: disassemble the seals,

lubricate their internal part and lubricate the piston. Do
not lubricate the O-ring.

The use of other lubricant cancels the warranty
of this pipette.

Reassemble the pipette (refer to the figure, page 10).
Tighten the connecting nut (turn

counter-

clockwise).

Refit the tip-ejector (see above).

Changing the seals

The O-ring and seal are on the piston; they must not be auto­claved, if worn or damaged in any way (chemical or mechani-

cal), they must be replaced. As the models P2L and P10L, F1L,
F2L, F5L and F10L contain miniaturized parts, it is best not to
disassemble these pipettes yourself, please contact your local
Gilson authorized Service Center.

The dimensions of the O-ring vary depending on the model
of pipette.

Remove the tip-ejector (see above).
Unscrew the connecting nut by turning it

clockwise.
Carefully separate the lower and upper parts.
Remove the piston assembly, O-ring and seal.
If necessary clean the piston and replace the seal; lubricate

them lightly. Please place them in the correct order.
Reassemble the pipette (refer to the figure, page 10).
Tighten the connecting nut (turn

counter-

clockwise).

Refit the tip-ejector (see above).

12B  MAINTENANCE FOR THE MULTICHANNEL MODELS ONLY

You may refer to the decontami­nation procedure available on the
Gilson website (www. gilson.com).

Liquid must never enter the up­per part (handle) of any pipette.

13  CLEANING AND DECONTAMINATION

PIPETMAN L is designed so that the parts normally in contact with liquid contaminants,
can easily be cleaned and decontaminated. However, because the models P2L and
P10L, F1L, F2L, F5L and F10L contain miniaturized parts, it is best not to disassemble
these pipettes yourself; please contact your local Gilson authorized Service Center.
