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 N
2
, 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 N
2
performance
is maximized by increasing the sample’s surface area,
increasing temperature and directing gas over the
sample.
