Simple, Reliable, Vacuum-Free, Sample-Safe

  • Vacuum-Free - no bumping or splashing to risk sample purity and yield
  • Centrifugal Evaporation - sample securely pressed in spinning containers
  • Versatile - ideal for LC fractions, synthesis reactions, harsh inorganic chemistry, cold room operators, toxic compounds, radioisotopes
  • Temperature - programmable ambient to 60o C
  • Off-Timer - programmable from seconds to hours
  • Green Solvent Recovery - captured gas recirculates in a closed system; toxic materials are contained
  • Flexible - concentrate samples or evaporate to complete dryness
  • Containers - use storage bottles, microtiter plates, or scintillation vials
  • Low cost - request a quote

The Centrifan RE uses self-generating blow-down technology to evaporate samples without a vacuum pump within a closed system. The lab-scale evaporator uses centrifugal force to protect samples from loss and cross-contamination enabling reliable, sample-safe drying of toxic compounds.

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

  • 8 x 100/250 mL storage bottles
  • 24 x 20 mm x 150 mm test tubes
  • 24 x 13 mm x 100 mm test tubes
  • 4 x 96-well microtiter plates
  • 24 x 20/40 mL scintillation vials

Rotors for proprietary sample containers have been produced.

Space Saving Design
The compact Centrifan RE can be located anywhere on the lab bench rather than taking up space in a fume hood. 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 presses the non-volatile compounds securely in place. s of sample during the evaporation process.
