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 N2performance 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.

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.
