The Centrifan PE employs a novel, recirculating evaporation technique that reuses a captured volume of gas and generates its own gas flow to rapidly evaporate samples in standard 20 mL scintillation vials. The technique eliminates the need for a vacuum pump or a large supply of blow down gas. Hazardous vapors are captured in a cold trap which prevents the release of toxic fumes. The unit may be purged of air with a nitrogen bleed to perform oxygen-free drying.  
  
The Centrifan PE incorporates a spinning rotor with fan blades that generate a high flow rate of drying gas which is directed onto the surface of the solvent contained in the scintillation vials. The rotor generates centrifugal force to keep 100% of the solute pressed in the scintillation vials, thus preventing compound loss and cross contamination. Solvent vapors from the trapped volume of gas are continuously flowed through a secondary loop with a dry ice cold trap to eliminate solvent vapors. The Centrifan PE operates without vacuum, which eliminates the potential for cross contamination and sample loss caused by solvent bumping.  
  
With a small 8 in. x 8 in. footprint and only 18 in. high, the Centrifan PE is self-contained, requires little bench space, and doesn't need to be placed beneath a fume hood. The device accommodates up to six 20 mL scintillation vials. Rotor inserts for Eppendorf and Agilent vials will be available shortly.
