Original instructions
The tables in Appendix C: CentriVap Specifications indicate approximate times
required to evaporate various common solvents. Actual times must be determined
by the user. The CentriVap can be set to alarm after a preset period of operation.
When the time expires, the CentriVap will give an audible alarm and turn itself
off.
Heat Boost Operation
Some CentriVap models are equipped with a secondary “Heat Boost” heater,
which is positioned on the sidewall of the chamber near the top. It provides
additional heat to the samples to speed evaporation. The “Heat Boost” heater is
controlled by the microprocessor to maintain the set point temperature at the
bottom of the chamber to prevent excessive overheating of the samples.
