With the revolutionary oil free ChemStar Dry vacuum system, you get the advantages of two combined technologies: roots blower and diaphragm vacuum pump. The result is an oil-free, software-driven vacuum system, ready to work on your tough chemical applications.

ChemStar® Dry was developed for laboratory operations which require high pumping speed and deep vacuum, such as vacuum manifolds (Schlenk line), freeze dryer, vacuum oven and glove boxes. The system combines a proprietary vacuum blower with patented PTFE diaphragm technology to pump quickly down (150 l/min) to the working range for most evaporative operations (2.0 to 0.1 mbar) with an ultimate pressure of 10-2 mbar.
