Kimble® Black Phenolic Screw Caps with White Rubber Liner

This phenolic replacement screw cap is made of a special black phenolic material (mineral filled) and is designed to withstand the effects of repeated autoclaving. A white rubber liner/cap bond was selected to retain its adhesive properties during autoclaving. This cap is threaded from the liner down approximately to half the total weight. It is resilient and resistant to moisture vapor, provides a chemical barrier and is ideal for use in hermetic sealing and other contents requiring sterilization. Note: All caps / liners should be tested to ensure leak and compatibility performance with contents. Meets ASTM Specification E982, Class A requirements. Autoclavable. Color: Black.
