Chapter 4: Using Your CentriVap
As a general guideline, to speed the evaporation
process, the CentriVap temperature should be set as
high as possible as long as the temperature will not
damage the sample or cause the sample to bump.
Time Setting Guidelines
The CentriVap Concentrator has two timers. The
“RUN TIME” turns the entire concentrator off after the
user set period of time. This stops the rotation, turns
off the heater and vacuum pump and bleeds vacuum
from the system. The heater may be turned off prior to
the concentrator turning off so heat sensitive samples
may be protected from exposure to excessive heat after
the solvent has evaporated. To turn the heater off prior
to stopping the entire system, enter a set time into the
memory at the “HEATER TIME”. When the
programmed time expires, the heater will turn off but
the rotation and vacuum will continue until the run time
expires.
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 side
wall 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.
