DURAN® tamper-evident closure, GL 45, PP, blue/red, for DURAN® laboratory bottles

DURAN® GL 45 tamper-evident closure, with lip seal When first closed, the plastic ring settles firmly over the neck of the bottle. When the cap is opened, the perforation tears and the plastic ring remains on the neck. Thus, it can be seen at a glance whether the bottle is still originally sealed. Special features and advantages: By tearing off the plastic ring when first opened, it is easy to see whether the bottle is still originally sealed After initial unscrewing or loosening of the perforation, it can be used as an "ordinary" screw cap Compatible with all GL 45 threads and thus versatile High tightness due to PTFE-coated silicone seal Application: Sterile liquid transfer between containers, long-term storage and archiving of samples, connection for spinner vials and cell culture vessels
