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.
