The Membrane Cap made of PP (blue) for DURAN® laboratory glass bottles
Ideal for gas-generating media and autoclaving processes.
In the centre, there is a sealed-in membrane which allows for fast and sterile pressure compensation. The membrane is gas-permeable, for both low pressure and excess pressure, and liquid-tight at the same time. Pressure compensation takes place in both directions.
These characteristics simplify autoclaving (up to +140°C) as the membrane cap can be screwed tightly and fixed onto the DURAN® laboratory bottles. The risk of contamination is greatly reduced.
