NNTTRROODDUUCCTTIIOONN

Congratulations on your purchase of a Labconco RapidVap. Labconco
manufactures two types of RapidVaps - one utilizes vacuum and the other utilizes
nitrogen as an aid to evaporation. Each model is available for operation on 115V
or 230V.

Superior evaporation rates are achieved by the unique blending of several gentle
forces on the sample. Samples are subjected to a gyrating motion causing the
liquid to form a vortex configuration which greatly increases the surface area and
hence the ability to evaporate. A precisely controlled amount of thermal energy
can be supplied to the sample to heat it. In the vacuum model, the sample can be
subjected to a decreased pressure by the application of a regulated vacuum. In
summary, the vacuum model RapidVap performance is maximized by increasing
the sample’s surface area, increasing temperature and decreasing pressure.

In the RapidVap N2, a stream of nitrogen or dry gas is directed downward onto the
surface of the sample. This reduces the partial pressure directly over the liquid to
speed evaporation and helps remove the solvent as it evaporates. In summary, the
RapidVap N2 performance is maximized by increasing the sample’s surface area,
increasing temperature and directing gas over the sample.

The gyrating motion imparted to the sample causes other, more subtle effects to
occur. Excellent mixing of the components in the liquid sample is obtained. Also,
as the liquid forms the vortex shape, a centrifugal force is established which forces
the liquid outward against the tube walls. This helps prevent bumping and in turn
allows the evaporation rate to be optimized.

The microprocessor which controls the operation of the heater and the motor
provides excellent regulation and reproducibility of protocols. The end of the run
can be signaled by the automatic end point system or by a manually preset timer.
Nine different protocols can be stored in memory so exact test parameters can be
easily repeated.

115V models are equipped with a 20 Amp NEMA 5-20P plug. 230V models are
equipped with a 16 Amp CEE 7/7 plug. It may be necessary to remove the plug
and install a different plug to match the available receptacle.

Do not use any detachable power cord that is not adequately rated for the unit.

N'utilisez pas de cordon d'alimentation amovible qui n'est pas suffisamment
puissant pour l'unité.

Location and Exhaust Requirements

The RapidVap Vacuum Evaporation System should be located within a fume hood
if hazardous or flammable solvents are used. In all cases, regardless of the solvent
used, it is strongly recommended that the vacuum pump is located and vented in a
fume hood.

The RapidVap N2 Evaporation System should be located within a fume hood if
hazardous or flammable solvents are used. In all cases, regardless of the solvent
used, it is recommended that the exhaust hose is vented into a fume hood or other
laboratory ventilation device.

Do not position the unit so that it is difficult to operate the main
disconnect device.

Ne pas placer l'appareil de sorte qu'il est difficile de faire
fonctionner le dispositif de déconnexion principal.

Vacuum Pump Requirements

A vacuum pump must be provided by the user. For most applications, it is
recommended that the vacuum pump is capable of a free air flow of 63 L/min and

1.5 mbar vacuum although, in some applications other pumps may be satisfactory
or be required. The inlet fitting on the vacuum pump must be suitable for 0.50 I.D.
hose.

Biological samples, for example, are often dissolved in water, a high boiling point
solvent, and are often heat liable. Such samples require the high vacuum
achievable with a mechanical vacuum pump, usually with an ultimate vacuum of
7 x 10-3 mBar to achieve a good evaporation rate.

On the other hand, samples dissolved in methylene chloride, a low boiling point
solvent, can be efficiently concentrated using a water aspirator.

The nomograms in Chapter 4: Using Your RapidVap will help determine the
boiling point of a solvent at pressures below atmospheric. This can serve as a
guide to the appropriate vacuum source.

TO INSURE THAT AGGRESSIVE SAMPLES USED IN THE
RAPIDVAP DO NOT DAMAGE THE VACUUM PUMP, IT IS
RECOMMENDED THAT ALL INTERNAL WETTED PARTS
ARE PTFE OR PTFE COATED. TO PREVENT A HAZARDOUS
CONDITION, THE PUMP MUST BE SUITABLE FOR
HANDLING THE VAPORS FROM THE SOLVENTS THAT
WILL BE EVAPORATED IN THE RAPIDVAP.

CAUTION: When selecting the vacuum pump it is very
important to consider the flammability of the solvents that will
be used. If the solvents are flammable, an explosion proof
vacuum pump is recommended.

ATTENTION: Lors de la sélection de la pompe à vide, il est très
important d'examiner l'inflammabilité des solvants qui seront
utilisés. Si les solvants sont inflammables, d'une pompe à vide à
l'épreuve des explosions est recommandé

Vacuum Line Traps

When using a mechanical pump which is not corrosion resistant, a trap must be
used in the vacuum line to prevent damage from solvent vapors. This is most often
a condenser-type trap chilled with dry ice/acetone. When evaporating acids, it is
advisable to include a soda lime acid trap in the vacuum line. This adds additional
protection for the pump.

Several components within the RapidVap are made from
stainless steel and can be degraded if exposed to acids. Before
evaporating acids, be sure to contact Labconco.

Plusieurs composants du RapidVap sont en acier inoxydable et
peuvent être dégradés s'ils sont exposés à des acides. Avant de
s'évaporer acides, n'oubliez pas de contacter Labconco.

A moisture trap and radioisotope trap are also available. When evaporating high
boiling point solvents, a liquid trap should be positioned between the RapidVap
and the vacuum pump to prevent liquid from entering the pump. Refer to
Appendix D: RapidVap Accessories for ordering information.

Chemical Attack on RapidVap
Components

Your RapidVap Evaporation System is designed to be chemical resistant to most
compounds that are commonly used in the concentration processes that are
performed in it. However, by necessity, the RapidVap is comprised of a number of
different materials, some of which may be attacked and degraded by certain
chemicals. The degree of degradation is obviously dependent on the concentration
and duration of exposure. Some of the major components of the RapidVap that are
susceptible to degradation are as follows:

 If a rotary vane vacuum pump is used, most compounds used in the RapidVap

will degrade the oil if allowed to enter the pump. Generally, a rotary vane
pump is not suitable for use with the RapidVap.

 Diaphragm vacuum pumps sold by Labconco have wetted parts either made

from PTFE or protected by PTFE coatings and are suitable for nearly all
procedures.

 Glass lids are suitable for use with all common compounds.

When using compounds in the RapidVap that are hostile to the materials of
construction, it is imperative that the equipment is properly maintained.

 After each run, clean up all residues, spills, and materials that might have

splashed in the chamber using agents suitable for the substance involved.

 When using a rotary vane pump the oil in the pump should be checked often. It

must be changed if it is cloudy, shows particles or is discolored. The useful life
of vacuum pump oil can be extended if the vacuum pump is operated for an
extended period of time after the RapidVap run is over. This allows
contaminants to be purged from the hot oil. This must be done with the inlet to
the pump blocked off to prevent air from free flowing through the pump. If the
pump is operated at an elevated vacuum level, oil will be expelled from the
pump and damage will occur.

Solvent Safety Precautions

The RapidVap is not classified as “explosion proof.” It has been designed with
safety as a primary consideration and should be used in a prudent manner using

“good laboratory practices.” It has been designed for use with compounds as

described in the United States National Electrical Code Class I, Group D. The
block that holds the sample tubes may be programmed to run as hot as 100°C,
however, the heater element may normally run at 110°C. A thermal fuse limits the
heater to a maximum temperature of 130°C. It is important that the solvents used
are compatible with these temperatures. Do not evaporate solvents that have an
autoignition temperature below 180°C. Do not evaporate solvents that are
classified as Group A, B, or C by the National Electrical Code. Evaporate only
non-flammable or Group D solvents with autoignition temperatures 180°C or
above. Use of other compounds could cause an explosion.

Solvents used in the RapidVap may be flammable or hazardous.
Use extreme caution and keep sources of ignition away from the
solvents. When using flammable or hazardous solvents, both
the RapidVap and the vacuum pump should be operated inside
a fume hood.

If a sample is spilled in the chamber it must immediately be
cleaned up.

Hazardous materials such as strong acids or bases, radioactive
substances and volatile organics, must be handled carefully and
promptly cleaned up if spilled.

Several components of the RapidVap which are located inside
the chamber are made of stainless steel which can be attacked
by acids. Use of acids such as trifluoroacetic acid can result in
degradation of the product and the vacuum pump if the
vacuum system is being used. Use care when using aggressive
liquids which can damage the RapidVap and thoroughly clean
the RapidVap after each use. Contact Labconco before
evaporating acids.

After your RapidVap has been installed as detailed in Chapter 3: Getting Started,
you are ready to begin using your RapidVap. Read this chapter to learn how to:

 set operating parameters.
 operate the controls.
 properly select and position glassware inside your RapidVap.
 understand the display.
 interrupt a cycle after it has begun.

Do not use the RapidVap in a manner not specified by the
manufacturer (refer to Appendix C: RapidVap Specifications).
The electrical protection properties of the RapidVap may be
impaired if the RapidVap is used inappropriately.

Planning

Thoroughly understand procedures and the equipment operation prior to beginning
work. The unique performance of the RapidVap Vacuum is dependent upon the
proper balance of heat, vacuum and vortexing action. If the proper balance is not
established, it is possible to damage or lose a portion of the sample. Therefore, if
you are unfamiliar with the RapidVap or are attempting a new protocol, it may be
helpful to make a trial run that is void of the sample you are attempting to
concentrate.

Select the size of the sample tube so it is compatible with the block. Tubes should
not be loose in the block. Blocks are available with holes for various size tubes.
Refer to Appendix D: RapidVap Accessories for available block sizes and pages 19
and 20 for recommended usable tube volumes and vortex speeds.

The unique performance of the RapidVap N2 is dependent upon the proper balance
of heat, gas flow and vortexing action. If the proper balance is not established, it is
possible to damage or lose a portion of the sample. Therefore, if you are
unfamiliar with the RapidVap N2 or are attempting a new protocol, it may me
helpful to make a trial run that is void of the sample you are attempting to
concentrate.

Determine if the sample which is to be processed will be allowed to go to dryness
or whether the evaporation is to cease prior to dryness. If the process should not
go to dryness, the proper sample tubes must be selected to allow the desired
amount of solvent to remain in the tubes. Sample tubes are available for various
end point volumes. Refer to Appendix D: Accessories for available sample tubes.
Any style ground glass tube may be used if the sample is to go to dryness,
however, flat bottom tubes evaporate the quickest.

Glassware Selection and Speed Setting
Guidelines

The speed at which the sample block should oscillate is dependent on the sample
tube size and the sample volume. Generally, the tube should be no more than half
full. The faster the speed, the higher the sample will vortex giving a maximum
surface area and therefore a maximum evaporation rate. However, if the speed is
too fast, samples will raise above the top of the tube and be lost. Smaller tubes can
be run faster than larger tubes. The following table gives recommended safe
speeds for tubes loaded with water. Experimentation with the specific sample may
determine faster speeds. When setting the speed, keep in mind that the sample will
raise up slightly in the tube when vacuum is applied to the chamber of the vacuum
model.

GLASS VIALS USED IN THE RAPIDVAP SHOULD BE OF
THE STYLE THAT DO NOT HAVE THE BEAD OR LIP ON
THE TOP EDGE. IF VIALS WITH BEADS ARE USED, THE
BEADS COULD HIT EACH OTHER AND BREAK THE
GLASS.

Four sample blocks are available for the RapidVap N2/48. Recommended speeds
are as follows:

Loading Glassware Into the RapidVap

Smooth operation of the RapidVap is dependent upon proper balance of the
machine. Therefore, if less than a full load of samples is run, it is important to
load samples into the RapidVap in a fairly uniform manner distributing the weight
of the samples and glassware evenly in the sample block.

IN ORDER TO MAXIMIZE THE PERFORMANCE OF THE
RAPIDVAP IT IS IMPORTANT THAT SOME OF THE
SAMPLES ARE CLUSTERED AROUND THE FRONT LEFT
HAND BLOCK MOUNTING STUD. THE BLOCK
TEMPERATURE SENSOR IS LOCATED ADJACENT TO THIS
BLOCK MOUNTING STUD. BY POSITIONING THE SAMPLE
NEAR THE SENSOR, THE SENSOR WILL DETECT THE
COOLING EFFECT OF THE EVAPORATING SAMPLES AND
SIGNAL THE CONTROLS TO SUPPLY MORE HEAT TO THE
SAMPLE BLOCK.

The best evaporation rate is achieved under conditions that maximize sample
surface area. These include using the largest tube possible, and using the highest
vortex speed possible.

When less than 8 samples are run in the RapidVap N2 or less than 48 samples are
run in the RapidVap N2/48, nitrogen flow can be directed to 2, 4, or 6 positions. It
is important to position glassware properly in the RapidVap N2 when less than a
full block is run to ensure that nitrogen gas is directed downward where the sample
is located. Note the label on the hub in the center of the chamber. This indicates
which nozzles on a RapidVap N2 or nozzle clusters on a RapidVap N2/48 will be
activated. If one or two positions are to be run, samples must be positioned at
locations identified (2). If three or four positions are to be run, samples must be
positioned at locations identified (4). If five or six positions are to be run, samples
must be positioned at locations identified (6). If seven or eight positions are to be
run, samples may be positioned at any of the locations. When using the RapidVap
N2/48, glassware may be placed anywhere within the activated cluster of nozzles.

Heat Setting Guidelines

The evaporation rate achieved by the RapidVap is dependent upon a variety of
factors. These include the nature of the solvent, the temperature, the pressure in
the vacuum system or the flow of the nitrogen gas in the RapidVap N2, the volume
of sample, shape of tubes and vortex speed. Because of the multiplicity of factors
it is impossible to give “typical” performance data.

By design, the RapidVap Vacuum model can be run at lower temperature settings
than the RapidVap N2 model. This is because the decrease in pressure will cause
the sample to evaporate at a lower temperature. As a general guideline, to speed
the evaporation process, the RapidVap temperature should be set as high as
possible as long as the temperature will not damage the sample or cause the sample
to bump.

In the RapidVap Vacuum models, generally the evaporation rate will be optimized
with the block temperature set and preheated 20 to 40°C above the boiling point of
the solvent at the operating pressure.

For example, methanol (which boils at 65°C at atmospheric pressure) boils at 5°C
at pressure of 53 mBar. Under these vacuum conditions, the block temperature
should be set between 25 to 45°C. The nomogram and equation to follow will help
in this determination.

Chapter 4: Using Your RapidVap

Original instructions

Calculating the boiling point:

The operating pressure corresponding to the desired boiling point temperature may
be calculated for any solvent using the following formula:

log P = 2.8811 – Ta – T
(b)(T)

Where P = Vacuum (mm Hg)

Ta = Boiling Point Temperature at Atmospheric
Pressure (°K)
T = Desired Boiling Point Temperature (°K)
b = Constant from Table

Useful conversion factors:
1 mBar = .75 mm Hg

°K = °C + 273

Using the nomogram:

To use this graph, three facts must be known about a given solvent:

1. Boiling point at normal atmospheric pressure (1 Bar).

2. Constant b.

3. Either operating temperature or operating pressure.

To determine the desired boiling point at a given pressure:

1. Find the boiling point at normal atmospheric pressure (1 Bar) on the left side of

the graph.

2. Find the operating pressure on the right side of the graph.

3. Draw a straight line linking these two points.

4. Find “Constant b” for the solvent on the top of the grid. Follow that line until

it intersects with the line as drawn between the two points. This point
represents the boiling point at the given pressure and the temperature is read
off the left or right side of the grid (0-250°C).

To determine the operating pressure necessary to achieve a given boiling
point:

1. Find the boiling point at normal atmospheric pressure (1 Bar) on the left side of

the graph.

2. Find the “Constant b” and follow this line to the desired boiling point on the

grid (0-250°C).

3. Draw a straight line linking these two points and extrapolate on the right hand

scale to find the operating pressure.

Time Setting Guidelines

It is often desirable to stop the concentration process before the solvent is entirely
evaporated. This is accomplished by using glassware that has a small diameter

stem on the bottom and using the “Time” function to shut off the process after a

predetermined interval of time.

The “Cool Zone” feature is available on the RapidVap N2 with 8 places and is not
available on the RapidVap N2 with 48 places.

The design of the RapidVap N2 causes the evaporation to proceed quickly when
the sample is in the larger upper chamber of the sample tubes. When the solvent
evaporates sufficiently to drop the level into the smaller stem, the evaporation rate
decreases significantly. This phenomenon allows the solvent in all sample tubes to
evaporate out of the large upper chamber before any of the small chambers are
completely evaporated dry providing that all sample tubes are filled with nearly the
same starting volumes.

Cool-Zone

When it is necessary to end the concentration process with the sample still
dissolved in a small amount of solvent, the time function should be activated and
the process time set to allow the solvent sufficient time to evaporate completely
out of the large upper portion of the sample tube and into the small lower portion

“Cool Zone.” This time can be approximated by knowing the starting sample size,

the desired end point volume, the stem size of the sample tube used and the
solvent. The tables in Appendix C: RapidVap Specifications indicate the
approximate time required to evaporate various common solvents. Actual times
must be determined by the user. When the set time has expired, the RapidVap N2
will give an audible alarm and turn off all RapidVap functions.

The tables in Appendix C: RapidVap Specifications indicate approximate times
required to evaporate various common solvents. Actual times must be determined
by the user. The RapidVap can be set to alarm after a preset period of operation.
When the time expires, the RapidVap will give an audible alarm and turn off all
functions.

To change the vacuum set point, press the set point select button directly under the

word “VACUUM.” An arrow will point to the last entered vacuum set point. The

vacuum level may be set between 0 to 999 mBar by pressing the increase or
decrease buttons. Above 999 mBar, the display will show “HI.” With a “HI”
setting, the vacuum pump will not operate. The last entered set point will be stored
in memory. Keep in mind that even though a deep vacuum set point may be
entered, the actual vacuum level that the RapidVap will try to maintain can be no
deeper than the vacuum level that the vacuum pump can maintain.

Select the number of samples that will be run (RapidVap N2 only):

Press the set point select button under the word “SAMPLE.” An arrow will point
to the last entered set point. By pressing the increase or decrease button, the
number of samples or clusters may be changed from 2 to 4 to 6 to 8. When
running less than eight samples in the RapidVap N2 or 48 samples in the RapidVap
N2/48, be sure to position them as described in the previous paragraph “Loading
Glassware Into the RapidVap.”

Operating The RapidVap

Never lift the lid if the block is moving. Samples may splash
out.

Ne jamais soulever le couvercle si le bloc est en mouvement. Les
échantillons peuvent éclabousser.

Never attempt to reach into the chamber if the block is moving.

Ne jamais tenter de mettre la main dans la chambre si le bloc
est en mouvement.

Keep hands clear of lid at all times and do not place objects on
the lid. Upon power up the unit may resume an interrupted
program and the lid may start moving.

Gardez les mains éloignées de couvercle à tout moment et ne
pas placer d'objets sur le couvercle. Dès la mise sous tension
l'appareil peut reprendre un programme interrompu et le
couvercle peut commencer à bouger.

1. Turn the power switch ON.

2. Select a program or set the set point parameters.

3. Turn on the nitrogen (RapidVap N2 only).

4. Preheat the block if desired.

5. Place samples in vials. Normally the vials should be no more than half full.

6. Load sample vials in the chamber.

7. Close the lid. On RapidVap N2/48 models, press down and rotate the cross bar

on the top of the lid counter clockwise approximately 1/8".

8. Swing both latches over the lid and tighten both knobs. Do not over tighten.

9. Press RUN. If the display was showing set point parameters, it will change to

show actual parameters. Press “RUN” again. The “S” (STOP) in the display

will change to “R” (RUN).

10. Set point parameters can be altered at any time during a run by first selecting

the parameter using the appropriate set point select button and then pressing
the “Increase” or “Decrease” switch.

11. If the time set point is used, at the end of the set time an alarm will sound. All

operating functions will cease.

12. Press STOP to terminate operation if the RapidVap has not already stopped

itself.

13. When the evaporation is complete, allow the chamber to stop moving, unlatch

the latches, on the RapidVap N2/48 models rotate the cross bar clockwise
approximately 1/8", lift the lid and remove the samples.

Original instructions

14. Any time the RapidVap is not in operation, the power switch should be turned

OFF. This will prolong the life of the cooling fan and the blower in the
RapidVap N2.

Operational Notes

The LCD display conveys various pieces of information. When the RapidVap is
turned on, the RapidVap will return to the same mode (RUN or STOP) that it was
in when the power was turned off. If the RapidVap was in the RUN mode when
the power was turned off, when the power is turned on, the RapidVap will attempt
to return to the programmed set points.

If the previous run is to be duplicated, it is important to press the program set point
button prior to pressing run. This will show all the set points for that program and
will reset the timer back to the programmed set point. Without pressing the
program set point button, the time will not be reset and will continue to count
down from the time at which it was stopped.

Interrupting a Cycle After it Has Begun

At any time during a run, the cycle may be stopped by pressing the STOP button.
This shuts off all operating functions. After the chamber stops oscillating, the
latches may be unlatched and the lid opened. If it is necessary to re-start the
RapidVap, close the lid and secure the latches and press RUN. The RapidVap will
resume operation at the same set point parameters and the timer will continue to
count down from the time at which the RapidVap was stopped.

End Alarms

The RapidVap has two means to signal the completion of a run. The first method is
determined by the operator when the run time is set as described in the previous
paragraph, Time Setting Guidelines. In the second method the RapidVap will
automatically sense when an evaporation process is nearly complete by comparing
temperatures in the unit. When the RapidVap detects end point, it will sound an

alarm and the LED next to the “PREHEAT/ END ALARM” button will flash. This
alerts the operator to closely monitor the run’s completion. This method performs

best when large samples are processed at high temperatures. When small samples
or low temperatures are used, the alarm may signal prior to the end of evaporation.

The audible alarm may be canceled by pressing the “PREHEAT/ END ALARM”

button. The LED will continue to flash until the “STOP” button is pressed. If the
button is pressed again, the audible alarm will become active again.

RS-232 Communications

Some RapidVaps are equipped with RS-232 communications capabilities. This
hardware and software allows a user to perform all the front panel functions from a
standard RS-232 link. Communications will be at 4800 baud, no parity, 8 bit
word, 1 stop bit, and a 3-wire interface (TXD, RXD and circuit common). The
RS-232 link will be duplex or two-way, that is, it will allow the RapidVap Basic
and N2 models to be controlled externally (incoming commands) as well as
provide status information coming out of the RapidVap (outgoing status). All
communications will be done in standard ASCII format using the programming
syntax below.

RS-232 Programming Syntax

The RapidVap only responds to commands sent by the connected computer or
terminal – it does not send out commands on its own. The programming syntax
has two forms:

1. # [command abbreviation letter] [value]; when the command requires a

numeric value.

2. # [command abbreviation letter ]; when the command does not require a

numeric value.

When the programming syntax contains a numeric value, it will change the
operation of the RapidVap. When the programming syntax does not contain a
numeric value, the RapidVap will respond with its current status for that command
value.

Note that the lead-in character is “#” while the “[ ]” (brackets) are shown only to
separate parameters for ease of understanding. These brackets will not be used in

the actual ASCII command string. Finally, the “;” is used to indicate the end of a

command. Also note that ‘\n’ indicates a newline character.

#e;

The RapidVap will respond to this command with a numeric

value as follows: 0=all functions are normal; “1”=lid is open;
“2”=communication problem; “3” and later numbers will be

established later as specific error messages

Note: When controlling the RapidVap using the RS-232 link, all control parameters
will be entered into program 9.

Note: All of the above commands can be sent with no numeric value, that is

‘#[command];’ (without value) to read out the setpoint and actual value without

changing the setpoint.

Note: There is no command for the vacuum release button on the front panel since
this button is momentary in nature – the “#V0000;” command will bleed the
vacuum chamber to atmospheric pressure.

Note: The above commands can be sent at a maximum rate of one command per
second.

The configuration of your RapidVap may need to be changed to accommodate
your needs. For example, you may want to change the sample size you are running
so you will need to change the block or you may want to add a lid heater to
eliminate condensation inside the lid. Read this chapter to learn how to:

 change blocks.
 install a lid with heater.

Changing the Sample Blocks

If it is necessary to change from one sample size to another, it may be necessary to
change the block. Refer to Appendix D: RapidVap Accessories for available
sample blocks.

First, using a 7/16" socket (RapidVap Vacuum and RapidVap N2), remove the
three nuts and washers on the top of the existing block. The RapidVap N2/48
requires a 9/16" socket to remove the three manifold guides that secure the block.
Lift the block out of the chamber. Note the asymmetric hole pattern of the three
mounting holes. Apply a small amount of heat transfer grease supplied with the
RapidVap to the end of the temperature sensor probe that extends up from the
bottom of the chamber.

Position the block over the three studs in the chamber. Install the flat washers and
nuts or manifold guide rods. Tighten securely.

Evaporation Rates

RapidVap Vacuum Models

The following tables show the approximate time to evaporate various solvents in
75mm and 16mm sample tubes when the sample block is fully loaded. Other
sample blocks are available for different size tubes. If they are used or if a
different number of samples is run at one time, the evaporation times can be
estimated from these charts or determined experimentally.

RapidVap N2 Models

The following tables indicate the approximate time required to evaporate various
common solvents. Tables A and B show the average time required to evaporate 8
samples from the selected beginning volume to a level where the solvent is at the
top of the Cool-Zone stem. Tables C shows the average time to evaporate various
solvents in different length Cool-Zone stems. It shows the average time for
solvents to evaporate from the top of the stem to the indicated remaining volume
when 8 vials are run simultaneously. The following example illustrates the use of
the charts:

Assume that a starting volume of 300 ml methylene chloride is
placed in a 600 ml sample vial with a 1.5 ml stem. The vial is
covered with a cap. The desired endpoint volume is 0.5 ml. From
Table A, the time to evaporate to the top of the stem is 59 minutes.
From Table C, the time to evaporate from the top of the stem to 0.5
ml is 17 minutes. Adding the two times together, the total time to
evaporate 300 ml of methylene chloride to 0.5 ml in a sample tube
with a 1.5 ml stem is approximately 76 minutes.

If fewer than eight samples are run at a time, the time to evaporate
will become shorter.

Evaporation Time in Upper Portion of Sample Vial

(600 ml Sample Tubes) (Time in Minutes)

N

Number of samples: 8
Nitrogen pressure: 10 psi at volumes 0 thru 300 ml
(see Note 1) 5 psi at volumes above 300 thru 350 ml
4 psi at volumes above 350 thru 400 ml
2 psi at volumes above 400 thru 450 ml
Vortex speed: 70% at volumes 0 thru 300 ml
(see Note 1) 36% at volumes above 300 thru 450 ml
Sample tubes covered with caps

Note 1: Even though the RapidVap N2 is capable of processing starting volumes
as high as 450 ml using the 600 ml sample vial, its optimum volume is 300 ml.
Above 300 ml, the vortex speed must be reduced and the nitrogen pressure must be
decreased to prevent the sample from splashing out. This data for starting volumes
over 300 ml was generated by starting the evaporation at reduced levels of nitrogen
pressure and vortex speed. As the solvent evaporated, the nitrogen pressure and
vortex speed were increased.
