RapidVap N2 Dry Evaporation System
The RapidVap N2 Evaporation Systems offer a more efficient, automatic alternative to Kuderna-Danish and rotary evaporators and may be used with a broad range of aggressive chemicals. In RapidVap N2 Systems, a stream of nitrogen or dry gas is directed downward onto the surface of the sample. Nitrogen blows down reduces the partial pressure directly over the liquid to speed evaporation and help remove the solvent as it evaporates. Nitrogen may be programmed for 2, 4, 6 or all 8 tube locations. Vortex motion and dry heat may also be applied to further accelerate processing.
The block holds eight large samples, up to 450 milliliters each, making it efficient for environmental and residue testing. An accessory block that holds eight 170 milliliter tubes suitable for solid phase extraction is also available. In many of these applications, the samples should not go to dryness. The unique Cool-Zone block and tube design significantly reduces the evaporation rate after end point is achieved. The Cool-Zone insulates the samples and allows the researcher adequate time before the samples reach dryness to remove them or to perform solvent exchange procedures. Alarms that signal when timed end point has occurred and when the RapidVap senses that the process is nearing completion allow for unattended operation.
