Vaccum Pumps

Rotary vacuum pumps with directly connected oil seal prevent air reflux and provide high vacuum pressure for vacuum ovens. And in order to get rid of evaporated oil or to block oil in-flow, an optional oil mist trap is recommended. (Refer to Page 69 for additional information.)
CTB-10 cold trap baths equipped with two U-type glass traps prevent a vacuum pump from vapors or contamination.
