DURAN YOUTILITY GL 45 Membrane Venting Screw Cap

Description

Manufactured from PP plastic, PTFE | 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-mum ePTFE membrane, combined with larger ventilation openings. Higher gas exchange rates for cell culture applications in bottles and shaker flasks. Maintaining the necessary gas environment CO2 and O2 for cell growth in incubator culture | 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
