DURAN® GLS 80® Membrane Vented Screw Cap, wide neck, PP, blue DURAN® Original GL laboratory bottles with screw cap are ideal containers for sterilisation and storage of media or buffer solutions. However, it is strongly recommended that caps are only screwed on loosely for the autoclaving cycle. The heating time is reduced if the steam can penetrate the bottle contents more easily. Loosely fitted caps also reduce the risk of breakage due to pressure build-up in the bottle, which can reach up to 400 kPa (absolute). In addition, if the caps are screwed on tightly immediately after autoclaving, a vacuum caused by steam cooling will occur. This can lead to bottle breakage and is therefore essential to consider, especially with larger bottles. To overcome these limitations, the vent screw caps with ePTFE membrane have been developed. The screw cap can be tightly closed as the membrane allows automatic sterile gas exchange and thus safe pressure equalisation during the autoclaving cycle, while ensuring the sterility of the bottle contents. Special features and advantages: Pressure equalisation during steam sterilisation The microporous structure of the membrane made of ePTFE allows sterile gas exchange in two directions, but prevents the penetration of liquids or solids and the bottle contents remain sterile The PTFE membrane and its polypropylene mesh backing are ultrasonically welded to form a durable seal The PTFE membrane and its polypropylene mesh backing are ultrasonically welded to form a durable seal Cost-effective, (Replacement is recommended after 3 to 5 autoclaving cycles, or if the membrane is damaged or contaminated) Compatible with all GLS 80 threads and therefore versatile Application: Autoclaving of media and buffer solutions, storage and transport of sterilised media, storage and transport of gas-forming media, short-term storage of sterilised media, storage of media and reagents DURAN® GLS 80® Membrane Venting Screw Cap (PP, blue), welded-in PTFE membrane.
