Operating the RapidVap Vertex
Evaporator
1. Turn the power switch ON.
2. Turn the nitrogen supply on.
3. Select a program or set the temperature and time parameters. Solvents
will evaporate quicker at warmer temperatures. Use care to avoid
damaging the samples.
4. Preheat the block if desired.
5. Open a nitrogen control valve for the row of nozzles to be used. Make
sure the lid is closed.
6. Set the nitrogen pressure by first selecting the rows of nozzles to be used
during the run. Then press run to open the gas supply valve. Pull out the
regulator knob and turn the knob until the desired pressure is displayed in
the center of the knob. Evaporation rates will be higher at increased
pressure. However, splashing of the sample may occur. It is advisable to
perform a set up run void of analytes to determine the optimal pressure
for the tube and sample size being used. Push the knob in. Turn off the
gas supply by pressing Stop or open the lid.
7. Place samples in vials and place vials into the block. If monitoring actual
sample temperature, place the temperature probe into sample vial making
sure the wires do not cover any nozzles. Close the lid.
8. Press "Run" on the display.
9. At the end of the programmed time the heater and nitrogen flow will turn
off. If the display time was set to ON, the run continues until "Stop" or
"Pause" is pressed.
10. The lid may be opened and samples removed. Use caution because the
block and samples may be hot.
