With welded-in expanded PTFE filter membrane, for pressure equalisation during autoclaving, or high gas exchange rates in cell culture


Manufactured from PP, ePTFE


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 0.2µm ePTFE membrane, combined with larger ventilation openings. Higher gas exchange rates for cell culture applications in bottles and shaker flasks


The PTFE 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
