Tamper-evident screw cap from PP, for laboratory bottles with DIN thread GL 45

The tamper-evident screw cap is available with lip seal or PTFE1 coated silicone seal2. The integral plastic ring tears when the cap is first opened and is retained on the
bottle neck. Therefore it can be clearly seen whether the bottle retains its original seal. After initial removal, can be used as “normal” screw cap.
Typical applications: secure storage and transport/shipping of valuable media.
