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, 3 of them automated and one manual, hosting different tube sizes to satisfy multiple needs.
The MultiVap 54 is the latest multi-channel and multifunctional parallel instrument designed by LabTech, including all accessories and functions to ensure the highest standard of effi ciency, speed, reliability, throughput and safety of any concentration process.
The LabTech MultiVap 8 system increases the capacity and sample throughput in laboratories and maintains quality and low cost. With this system it is possible to evaporate to solid state or concentrate into a fixed end-point volume. A compact solution compared to conventional rotary evaporators, with the possibility to be used outside the fume hood thanks to the integrated vapor evacuation system.
