Additional information


GL 56


Pressure equalisation during steam sterilisation
The microporous structure of the ePTFE membrane enables sterile gas exchange in two directions, while blocking the penetration of liquids or solids and the bottle contents remain sterile
Increased gas exchange rate due to thin 0.2-μm ePTFE membrane, combined with larger ventilation openings
The ePTFE membrane and its polypropylene mesh support are ultrasonically welded in place forming a durable seal
Cost effective as the caps can be reused several times (Replacement is recommended after 3 to 5 autoclave cycles due to durability, or if the membrane becomes damaged or contaminated)
Polytetrafluoroethylene (ePTFE) membrane (conforms to USP 121 °C Class VI) with polypropylene mesh
