The Centrifan PE Evaporator/Concentrator from KD Scientific provides a low-cost, safe, small volume evaporator for synthetic and medicinal chemists, as well as pharmaceutical, biotech and university researchers. It dries solvents directly in the vial, increasing evaporation efficiency in the laboratory. Proprietary self-generated blowdown technology eliminates the potential problems with common evaporation systems such as vacuum centrifuges, rotary evaporators, nitrogen blow-down and freeze dryers. Synthetic and medicinal chemists can save time because the evaporator dries samples without the monitoring required by a rotorvap. The system also works well for processing fractions collected from flash liquid chromatography. Pharmaceutical and university labs working with radioactive and other highly toxic compounds will appreciate the advantage of the green chemistry design. In the evaporator, samples are dried in 20-mL scintillation or other common vials and there is no need for a vacuum pump or a large supply of blow-down gas. This protects samples from loss and captures toxic vapors and materials in a closed system.
