Eliminating solvent bumping & foaming during evaporation

Chimica Oggi-Chemistry Today

Genevac reports that its proprietary Dri-Pure® technology, available as standard on Series 3 HT, EZ-2 and Rocket Synergy evaporators, enables scientists to rapidly dry their samples without foaming, cross-contamination or loss of sample due to solvent bumping.

The unique Dri-Pure® technology works by reducing pressure in the evaporation chamber in combination with an increase in rotor speed to achieve greater g-force and carefully controlling heat flow to the sample during the pressure ramping stage. Embedded in the Genevac evaporator software and hardware, Dri-Pure works automatically without need for user intervention eliminating solvent bumping or foaming and enabling controlled ‘sample-safe’ solvent removal in the minimum time.
Dri-Pure® offers significant benefits and is widely proven to eliminate cross contamination during parallel evaporation in EZ-2 and HT evaporators. Dri-Pure® on the Rocket Synergy evaporator has been more recently demonstrated to prevent foaming often seen in batch evaporation of large volumes such as are generated by natural product extractions. Combining Dri-Pure® with the auto-stop when dry capability – Genevac evaporators offer truly unattended evaporation freeing scientists to perform other tasks confident that their samples will be dried without cross contamination or thermal damage.
