Sterile-venting membrane screw caps, DURAN®
Sluitingen Flesdoppen
Ideal for autoclaving processes because the 0,2 micron ePTFE membrane permits pressure equalisation and tight sealing, greatly reducing the risk of contamination. Ingress of liquids or solids is prevented and the bottle contents remain sterile.

  • Membrane caps can be autoclaved at 121 °C (20 minutes) or 134 °C (3 minutes)
  • Cost effective as the caps can be reused several times
  • Convenient as six caps are available allowing the use with a large range of bottle sizes from 10 ml up to 3500 ml
  • Biocompatible: The ePTFE filter material conforms to USP 88 121 °C class VI
  • The PTFE membrane and its polypropylene mesh support are ultrasonically welded in place forming a durable seal

The microporous structure of the expanded polytetrafluoroethylene (ePTFE) membrane enables sterile gas exchange in two directions while blocking the flow of high surface tension aqueous liquids like water. New, thinner ePTFE membrane combined with larger vent holes increase the rates of gas exchange
