10.
Press “STOP” to terminate operation if the CentriVap has not already stopped
itself.
11.
When the evaporation is complete, allow the rotor to stop moving, lift the lid
and remove the samples.
Operational Notes
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 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.
Interrupting a Cycle After it Has Begun
At any time during a run, the cycle may be stopped by pressing the “STOP”
button. This shuts off all operating functions. After the rotor stops, the lid may
be opened. If it is necessary to re-start the CentriVap, close the lid and press
“RUN.” The CentriVap resumes operation at the same set point parameters and
the timer continues to count down from the time at which the CentriVap was
stopped.
Gas Ballast
The vacuum pump incorporated in the CentriVap DNA Concentrator is capable of
achieving an ultimate pressure of <7 MBAR. Some solvents may freeze when
exposed to low pressure. If the sample being processed freezes, evaporation
ceases and the sublimation process occurs, which in turn greatly reduces the
concentration rate. Freezing of the sample may be prevented by opening the gas
ballast valve which increases the ultimate pressure in the system. Pressure may
be monitored using a vacuum gauge as described in Chapter 6: Installing a
Vacuum Gauge.
