New Centrifan™ Recirculating Evaporator (RE) Dries Fractions up to 5x Faster Without Using a Vacuum Pump

The Centrifan RE evaporates fractions 3 - 5 times faster* than conventional benchtop vacuum centrifuges or blow down concentrators without the need for a vacuum pump. The standalone device utilizes the gas flow created by a spinning rotor along with a heater to dramatically accelerate the evaporation of aqueous and organic solvents. Compared to traditional benchtop concentrators that use either a water bath or infrared lamps, the Centrifan RE provides a more efficient, sample-friendly drying environment.

Operating without a vacuum pump, the Centrifan RE saves energy, laboratory space, maintenance, and eliminates oil cleanups, heat, noise and vacuum tubing. The Centrifan RE employs a unique recirculation process (patent pending) that redirects the gas flow created by the rotor through passages to the surface of the liquid inside the evaporation vessel. This aggressive blow drying continuously sheers off the top layer of the liquid while the centrifugal force holds the non-volatile compounds securely in place. Tests with talcum powder demonstrated a 0% loss of sample during the evaporation process.

The Centrifan RE is available with standard rotor configurations for either four or eight 250 mL storage/media bottles (custom configurations are available). The device is available at a special summer promotional price of $8,550 if purchased before July 31, 2009.
