RapidVap N2 and N2/48 Evaporation Systems are multiple-sample evaporators that use a combination of gentle forces — vortex motion and dry heat with nitrogen blow down — to quickly reduce samples to dryness or an end point volume. RapidVap Vertex Dry Evaporators use dry heat and nitrogen blow down to speed evaporation of up to 50 small samples at once. Unlike water bath heaters, dry block heaters require less maintenance, no distilled water or additives, and adds no potential source of contamination.
