Solvent Safety Precautions
CAUTION: The CentriVap 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 heater 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 120°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.
CAUTION: Solvents used in the CentriVap may be flammable or hazardous.
Use extreme caution and keep sources of ignition away from the solvents.
When using flammable or hazardous solvents, the CentriVap should be
operated inside a fume hood.
If a sample is spilled in the chamber it must immediately be cleaned up.
Hazardous materials such as strong acids or bases, radioactive substances and
volatile organics, must be handled carefully and promptly cleaned up if spilled.
Do not store flammable or hazardous solvents within 12 inches (300 mm) of
the CentriVap.
IMPORTANT: Various Federal, State or local regulations may govern the
disposal of substances used in connection with this equipment. All users of
this equipment are urged to become familiar with any regulations that apply
in the user’s area concerning the dumping of waste materials in or upon
water, land or air and to comply with such regulations.
