Vacuum Pumps
MARSHALL SCIENTIFIC Buchi V-800 Vacuum Controller
The Buchi V-800 Vacuum Controller is a stand alone valve unit for operation with external vacuum systems, such as the Buchi V-500 vacuum pump which works with the R-200 or R-205 rotovap systems. The V-800 regulates vacuum speed at variable set points and controls constant vacuum. The controller features large LCD display in mbar or torr.

Chemglass Life Sciences Vacuum Pump, Two Head, 17L/min, 10 Torr, 115V, 60Hz
Vacuum Pump, Two Head, 17L/min, 10 Torr, 115V, 60Hz. The Chemglass series of all PTFE vacuum pumps are an excellent source of vacuum in the laboratory. They eliminate the concern about chemical attack to the pump or contamination of your pumped medium. Solid PTFE heads do not blister or peel, and advanced Kalrez valves along with our unique PTFE coated, molded structure diaphragm provides the longest possible lifetime when pumping corrosive gases. They are perfect for use in rotary evaporation, vacuum distillation, vacuum filtration, gel drying or the transfer of corrosive gases. Using no house air or water for its operation, it conserves valuable resources and helps protect the environment by eliminating the disposal of solvent contaminated waste water or oil.
