Screw cap, GLS 80

Quick release closure for DURAN® GLS 80® laboratory bottle with PTFE coated seal, from PSU compound

The material used is a special compound based on a polyarylsulphone. Consequently the chemical, thermal and mechanical properties of the material are noticeably improved and matched to laboratory requirements. Thanks to the thread, the DURAN® GLS 80® bottle can be opened and closed with only a three-quarter turn. The seal, which is coated on both sides with PTFE, ensures the bottle can be tightly closed. A matching PTFE pouring ring is available, permitting clean, drop-free use. Temperature resistant up to +180°C. Autoclavable.
