Pump heads are manufactured from corrosion-resistant Teflon and Kales. Patented multi-port valve design increases performance and tolerates liquid droplets drawn into the system without damage. Single Stage Pumps are ideal for applications to include filtration and blotting and serve well as a general-purpose vacuum source. Lightweight pumps are easy to use and can pull a vacuum to 75 tort (27" Hg). Two Stage Pumps are great for use with concentrators, rotary evaporators and distillation equipment. These pumps are the perfect companion for laboratory appliances with the ability to provide vacuum to 6 tort (29.7 Hg) and pressure to 15 psig. Two Stage Heavy-Duty Pumps are the perfect companion for vacuum ovens and vacuum concentrators, especially with difficult-to-evaporate solvents like water. Pull to 1.5 tort (29.86 Hg) and push to 15 psig.
