Laboratory glass bottles

Membrane screw cap

from PP, blue, with welded-in PTFE membrane for pressure equalisation

For all GL 45, GL 32 and GL 25 threads. Ideal for autoclaving processes because the membrane permits pressure equalisation and tight sealing. Hence the risk of contamination is greatly reduced. Ingress of liquids or solids is prevented and the bottle contents remain sterile.

Typical applications: storage or transport of gas generating media, autoclaving of media.

Tamper-evident screw cap

from PP, for laboratory bottles with DIN thread

Tamper-evident screw cap available with lip seal or PTFE coated silicone seal. 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 first untwisting, can be used as "normal" screw cap.

Typical applications: secure storage and transport/shipping of valuable media.
