Description
DURAN® GLS 80® connection system screw cap with four GL 18 ports and O-ring seal is a flexible modular closure for transferring liquids or gases in the laboratory. Manufactured from polypropylene (PP) and EPDM in blue, grey and white, it accepts five tubing diameters of 3,2 mm, 6,0 mm, 8,0 mm, 10,0 mm and 12,0 mm. Unused ports can be closed with a blank GL 18 PBT cap, while sterile pressure equalisation is possible by fitting a syringe membrane filter. The modular building-block design lets users combine components to match specific process needs. Fully compatible with all GLS 80 threads, this connection system from manufacturer Duran/DWK Life Sciences supports liquid transfer, feeding of media into bioreactors, reagent supply to instruments and photobioreactor operation. The O-ring seal ensures reliable performance during media handling and gas exchange. Supplied in a pack of two pieces, the cap offers adaptable port configuration and robust construction for modern biotech and analytical workflows.

Questions about DURAN® GLS 80® Connection Cap System, screw cap, 4 GL 18 ports and O-ring seal
What is this article?
DURAN® GLS 80® Connection Cap System, screw cap, 4 GL 18 ports and O-ring seal is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
