9. Press “RUN.” If the display was showing set point parameters, it will change
to show actual parameters. Press “RUN” again. The “S” (STOP) in the
display changes to “R” (RUN). The program on the display alternately
displays “R” or the number of the program that is running. If you intend to
run program 1, 2 or 3, simply press “PROG 1,” “PROG 2” or “PROG 3” to
quick start the CentriVap. The rotor will start, the vacuum break valve will
close and the vacuum pump will start after the rotor reaches operating speed.
10. Set point parameters can be altered at any time during a run by first selecting
the parameter using the set point “SELECT” button and then pressing the
“INCREASE” or “DECREASE” switch.
11. If the run time set point is used, at the end of the set time an alarm sounds. All
functions cease.
12. Press “STOP” to terminate operation if the CentriVap has not already stopped
itself.
13. When the evaporation is complete, allow the rotor to stop moving, lift the lid
and remove the samples.
CentriZap™ Strobe Light
The CentriZap will enable you to see the samples as they are rotating in the rotor.
To use the strobe light while the CentriVap is operating, remove the light from its
holder on the front of the unit, press the trigger and shine the light on the samples
in the rotor.
Operational Notes
As solvent is evaporated in the Concentrator and then condensed in the Cold Trap,
it is normal for the Cold Trap temperature to rise as its load increases.
Depending on which solvent is used, the volume of the sample and the system
operating parameters, the Cold Trap may warm up sufficiently to cause the
“READY” indicator to turn off. As the sample reaches completion, the load on
the Cold Trap will decrease and its temperature will decrease. The “READY”
indicator will once again illuminate.
When the CentriVap is turned on, the CentriVap returns to the same mode
(“RUN” or “STOP”) that it was in when the power was turned off. If the
CentriVap was in the “RUN” mode when the power was turned off, when the
power is turned on, the CentriVap attempts to return to the programmed set points
and continue the run.
To reset the timers to the original set point when running programs other than
program 1, program 2 or program 3, press the start button and hold it for five
seconds. The display will indicate that the timer is reset.
