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

will give an audible alarm and turn off all RapidVap
functions.
