• 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.
With prudent maintenance your RapidVap will provide
years of service. Warranty on the effected parts will be
void if maintenance has obviously been neglected. If
you have questions about using specific compounds in

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.
