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.

The RapidVap Vacuum Evaporation Systems accommodate twelve different, interchangeable accessory sample blocks holding sample volumes from just a few milliliters to as large as 450 milliliters. As many as 110 each 12 or 13 mm tubes may be loaded at once. Additional blocks accommodate various tube types including conical centrifuge tubes and scintillation vials. Contact Labconco about custom blocks to fit special glassware configurations such as VOA vials.

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 blow 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.

RapidVap N2/48 Evaporation Systems use nitrogen blow down, vortex motion and heat to speed evaporation of up to 48 small samples or eight 450 milliliter samples at once. A stream of nitrogen or dry gas is directed downward onto the surface of the sample. Nitrogen blow down reduces the partial pressure directly over the liquid to speed evaporation and help remove the solvent as it evaporates. These Systems may be used to prepare samples for applications such as drug development and metabolism, bioresearch, combinatorial chemistry, environmental testing, forensics and toxicology.

There are eight clusters of six ports each. Nitrogen may be delivered to 2, 4, 6 or 8 clusters at once so that nitrogen is conserved when a full load is not required. Microprocessor-controlled vortex motion increases surface area for faster evaporation while continually mixing the sample to maximize recovery. Utilizing a dry block heating method, RapidVap N2/48 Systems provide a more reliable alternative to maintenance-intensive, contamination-prone water baths.
