Nitrogen Concentrators

Family Brief

Nitrogen concentrators are an alternative to rotary evaporation mainly in case of small volumes (under 50 mL) and a large quantity of samples.  Nitrogen 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 dry nitrogen 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. LTCDS offers 3 fully automated nitrogen concentrator hosting different tube sizes to satisfy multiple applications. Nitrogen concentrators are the perfect sample preparation partner to LTCDS's line of automated solvent extraction instruments as well.
