Sample concentrator MultiVap 6

laboratory

Concentrators accelerate the evaporation by decreasing the partial vapor pressure of the solvent just above the surface of the liquid. Blowdown evaporators use a jet of gas to continually force off the layer of air that is saturated with vapor. By immediately removing molecules that enter the vapor state, the molecules do not have a chance to return to the liquid, which increases the evaporation rate. As said blowdown technique is very useful for small sample volumes because with larger samples nitrogen blowdown will take longer and semi-volatile compounds may be lost. Since the samples are immersed in a water bath, with programmable temperatures up to 100°C, the evaporation is further accelerated. LabTech offers 4 models, 2 of them automated and 2 manual, hosting different tube sizes to satisfy multiple needs. The MultiVap 6 is a basic, cost effective sample preparation instrument featuring 6 independent channels. Without transferring, samples are directly concentrated in the vial thereby reducing the risk of transfer loss, improving recovery and saving precious time. The nitrogen fl ow rate of each channel can be adjusted independently as well as the needles that can be adjusted up and down. The aluminum alloy heating block guarantees temperature uniformity for all samples.
