Laboratory concentrator MultiVap 96

sample

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 96, designed for microplates, features simple operation, practical and reliable performance. It is designed for sample concentration with high throughput e.g. sample preparation in drug screening, hormone analysis, liquid chromatography, and mass spectrometry. The system adopts the most advanced direct nitrogen heating technique with higher efficiency than the bottom dry block heating mode, as the heating uniformity is greatly improved, and samples can be heated up to the evaporation point in short time.
