Marprene process tubing
Overview
Marprene long life process tubing
Marprene is a long life thermoplastic elastomer with resistance to a wide range of chemicals. Marprene is highly resistant to oxidising agents such as ozone, peroxides and sodium hypochlorite.
Marprene is Watson-Marlow's exclusive thermoplastic elastomer peristaltic pump tubing. It lasts at least 10 times as long as tubing in other materials. Long-life tubing means stoppages for a tube change are rare events, easily fitted in with general maintenance.
Always our first recommendation, Marprene has wide chemical compatibility, and is highly resistant to oxidising agents such as ozone, peroxides and sodium hypochlorite. Marprene is beige and opaque to visible and ultraviolet light, with low permeability to oxygen, carbon dioxide and nitrogen. It meets USDA standards for food handling.
