Description
This used Rocker Chemker 400 Chemical Resistant Vacuum Pump is an oil-free laboratory diaphragm vacuum pump designed for chemically resistant vacuum applications. The pump is suitable for vacuum filtration, gel electrophoresis, solid phase extraction, solvent purification, degassing and general laboratory vacuum supply where resistance to corrosive vapours is required.
The Chemker 400 uses chemically resistant PTFE wetted parts and an oil-free diaphragm pump design, reducing contamination risk and maintenance compared with oil-sealed vacuum pumps. The direct-drive motor provides low vibration and quiet operation, while the thermal protection system helps protect the pump against overheating during use.
The pump was tested and the specs could be reached. It is in good working condition.
