Dry Samples Faster than Vacuum or Blow Down Solutions

  • No vacuum pump required to dry fractions faster than benchtop vacuum centrifuges or blow down concentrators.*
  • Save energy, laboratory space, and maintenance headaches by
    eliminating the need for vacuum pumps
  • Eliminate oil mess, heat, noise and vacuum tubing
  • Set temperature up to 60°C
  • Programmable heater shut-off time
  • Use storage/media bottles, microtiter plates, tubes or scintillation vials

*all evaporation rates were obtained while connected to a -50 degree C cold trap (cold trap is available separately).

Operates at Atmospheric Pressure
The Centrifan RE operates at atmospheric pressure and replaces typical vacuum centrifuges or blow down concentrators. Using only heating fins within the rotor compartment and the spinning rotor, the Centrifan RE provides a simple and effective evaporation environment.

Accommodates Standard Collection Vessels

  • 4 or 8 (250 mL) media bottles
  • 24 (20 x 150 mm) test tubes
  • 24 (13 x 100 mm) test tubes
  • 4 (96 well) microtiter plates
  • 24 (20 mL or 40 mL scintillation vials)
  • 6 x 0.3L wide mouth bottles

Custom rotor configurations are available.

Space Saving Design
The compact Centrifan RE fits inside a fume hood or can be located anywhere on the lab bench. Vapors are directed through an exhaust hose that can be connected to the laboratory vent system or directed to a cold trap for condensation.

The 160 cfm gas flow created by the rotor is redirected 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.

Comparative Performance Specs:

Centrifan RE dries aqueous samples 3X faster than standard vacuum centrifuges and 5X faster than blow down concentrators
