Description
DURAN® GL 45 Aluminium Screw Closure, silver, closed top, with high temperature cap liner (PTFE-coated red silicone)
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.
Features and Benefits:
Application: As alternative to plastic screw caps for laboratory bottles, High-temperature processing and applications, Low-temperature / cryogenic sample storage, Pharma API and sensitive material storage, The open topped Aluminium cap is a “non-plastic” alternative to the PBT plastic aperture cap
