Avoiding Sample Loss During Evaporative Drying

Dri-Pure® technology from Genevac offers significant benefits to scientists, especially those working in synthesis and purification.

This innovative technology enables scientists to rapidly dry their samples without cross-contamination or loss of sample due to solvent bumping.

Other methods of solvent removal tend to be very laborious or lead to unacceptable cross-contamination, Dri-Pure® running on a Genevac evaporator gives smooth, controlled solvent removal in optimum time. The patented Dri-Pure® technology is available for all current models of Genevac centrifugal evaporators, from the affordable EZ-2 through to the production-scale HT-24.

Genevac's unique anti-bumping system works by carefully controlling the reducing pressure in the evaporation chamber in combination with an increase in rotor speed to achieve greater g-force. In addition, heat flow to the samples must be reduced during the pressure ramping stage.  Dri-Pure® achieves all this via the embedded instrument software and hardware that makes such an elegant solution easy to apply.
