The material used for this GLS 80 closure is a special polymer based on Polyethersulfone PESU. As a result, the chemical, thermal and mechanical properties of the material are improved compared to polypropylene. Thanks to the shortened triple thread, the DURAN® GLS 80® bottle can be opened or closed with only a three-quarter turn. The seal, which is coated on both sides with PTFE, ensures the bottle can be tightly sealed (cap liner: platinum-cured silicone). A matching PTFE pouring ring is also available, permitting clean, drip-free use.

• Manufactured from Polyethersulfone (PESU), PTFE coated, platinum-cured silicone
• PESU caps and PTFE pouring rings offer greater thermal and chemical resistance than the equivalent polypropylene components
• Screw cap seal with PTFE coated, platinum-cured silicone for efficient sealing
• The matching PTFE pouring ring permits drip-free pouring and clean, safe working
• Suitable for autoclaving / steam sterilisation and for use up to 180 °C
