Operation; Adjust Flask Rotation - Heidolph Hei-VAP Precision Originalbetriebsanleitung

Adjust fl ask rotation

By increasing fl ask rotation you can increase your evaporation rate. A shorter evaporation
time may prevent thermal damage to your sample.
Depending on fl ask size and heating bath temperature different rotation speeds may be
suitable.
Speed range and setting
Rotation speed can be set from 10 rpm - 280 rpm.
➜ Test your selected fl uid
▪ with slowly increasing temperatures
▪ with different evaporating fl asks
▪ with increasing rotation speeds
➜ Note these results and make them accessible for all individuals.
