ROCKER Chemical Resistant Vacuum Pump 169300-22

Chemker 300 Chemical Resistant Vacuum Pump (part number 169300-22, AC220V/50Hz) is a laboratory diaphragm vacuum pump designed for handling corrosive gases and solvent applications. The pump provides oil-free, maintenance-free vacuum for tasks such as vacuum filtration, gel electrophoresis, solid-phase extraction (SPE) and solvent purification. Wetted parts are made of PTFE and FFKM to deliver high chemical resistance, and the unit includes built-in thermal protection for safe operation.

Key Features:

• Part number: 169300-22 (Chemker 300), AC220V / 50Hz
• Max. power: 60 W
