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.
With its oil-free characteristic, the system is the first practical alternative to oil-seal rotary vane pumps which are mostly used in such kinds of applications. There is no risk of pump damage due to skipped oil changes or maintenance as ChemStar® Dry is an oil-free system. Save the time, expense, and hassle of oil-seal vacuum pumping with ChemStar® Dry.
