Brand:Sterlitech
The Chemker Series by Sterlitech represents a specialized line of chemical-resistant vacuum pumps designed for laboratories handling aggressive vapors and corrosive gases. Every "wetted" part, the components that come into contact with the gas stream, is constructed from or coated with PTFE (Polytetrafluoroethylene). This ensures long-term durability when filtering acids, bases, or organic solvents that would typically degrade standard aluminum or plastic pumps.
