The RapidVap Vacuum Evaporation Systems are ideal for preparation of samples in a variety of applications including drug discovery, agrichemistry, mycology testing and environmental analysis. The systems use vacuum along with heat and vortex motion to help speed evaporation and provide an alternative to traditional centrifugal evaporation methods. These systems may be used with a broad range of aggressive chemicals. Heat is supplied by a dry block heating system that, unlike water baths, adds no potential source of contamination and requires no maintenance.
