Description
Aluminum is an alternative material to the plastic used in most screw closures for laboratory bottles. The caps are available as a closed-top cap with a high temperature PTFE coated cap liner, or as an open-top cap for use with septum or stopper. Metal closures offer a wide range of temperature tolerances and have a high mechanical strength. Aluminum offers superior barrier qualities that protect against light, moisture, oxygen, and other gases.
- Free of hydrocarbon-based plastics, plasticizers, phthalates, etc.
- High temperature usage up to +260 °C for depyrogensation or hot air sterilization
- Convenient: Thread fits all DURAN™ GL 45 glass bottles from 100 mL to 20 Litres
- Secure sealing with USP Class VI PTFE coated silicone cap liner
- Cap liner is supplied unmounted for easy processing and is replaceable
- Convenient opening and re-closing as the knurling provides extra grip for wet or gloved hands
- Protection: Electrically conductive material – ESD dissipation
