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 also available, permitting clean, drop-free use.
