Improve productivity over traditional rotorvap concentrators
No vacuum pump required - prevents risks of sample loss or contamination; eliminates oil mess and downtime from pump accessory
Increased user safety – no fragile glassware with implosion risk
No inconvenient water bath
Blow-down of liquid fraction solvent means no pre-freezing for subsequent lyophilization
Choice of inert recirculating blow-down gas; consumption of nitrogen or argon is negligible
Centrifuge-like operation (samples in spinning rotor) assures no loss of sample, even at complete dryness
Unattended operation - self-refilling of collection containers as evaporation progresses
Portable, self-contained unit requires no bench space or fume hood
Environmentally friendly - uses cold trap to recover evaporated solvent vapors
The Centrifan™ AF is a Recirculating Evaporation™ system with a unique Auto-Fill capability that allows unattended operation and provides significant advantages over traditional rotorvap concentrators. The system employs centrifuge-like operation and uses novel recirculating evaporation of a trapped gas volume to blow-down fraction solvent. The system functions without a vacuum to prevent sample foaming, bumping, freezing or contamination risks typically associated with vacuum type rotorvap concentrators. The Auto-Fill mechanism (patented pending) automatically determines when to replenish liquid in the evaporating sample containers while they continue to spin.
