Simple, reliable, vacuum-free, safe for samples and users

The Centrifan PE Evaporator / Concentrator is a small volume evaporator that eliminates the problem of bumping using SBT (Self Blowdown Technology). SBT allows solvent drying using heated, circulating gas flow and NO VACUUM PUMP ! 

The Centrifan™ requires a rotor for operation. Rotors are not included. Please review the accesories tab below for rotor options.

Features

Overview of the Innovative Centrifan PE Featuring Self Blow-down Technology

The KD Scientific Centrifan PE uses self-generating blow-down technology to evaporate samples without a vacuum pump within a closed system. Centrifugal force protects samples from loss and cross-contamination, freeing operators for other tasks. If you are using a rotary evaporator, see how the Centrifan™ PE can save 1-operator-hour per sample. 

Eliminate Sample Drying Risk while Freeing Operator Time

The Centrifan™ PE employs a novel, recirculating evaporation technique that reuses a captured volume of gas and generates its own gas flow to efficiently evaporate samples in standard 20mL scintillation vials. The technique eliminates the need for a vacuum pump or a large supply of blow down gas, significantly reducing cost, complexity, noise, and maintenance compared to rotary evaporators, vacuum centrifuges, and conventional blow-down equipment. Because it operates without vacuum, the Centrifan™ PE eliminates the potential for cross contamination and sample loss caused by solvent bumping. 

Vacuum-Free, Closed System Drying

The Centrifan™ PE has a spinning rotor with fan blades that generate a high flow rate of drying gas which is directed onto the surface of the solvent 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 prevent release of toxic fumes. The unit may be purged of air with a nitrogen bleed to perform oxygen-free drying.
