- DURAN® GL 45 Aluminium Screw Closure, silver, open topped, with 34 mm central aperture
Aluminium 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. Aluminium offers superior barrier qualities that protect against light, moisture, oxygen, and other gases.
