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.
