Description
neoChoice screw cap GL45 made of HDPE with quick coupling without shut-off is a laboratory bottle closure that integrates a versatile hose connection interface. The GL45 thread fits standard laboratory bottles, while the built-in connector accepts tubing via quick coupling, hose barb or olive fittings for rapid attachment. An additional polyethylene foam gasket ensures a reliable seal against the bottle neck, and a hydrophobic ventilation filter permits pressure equalisation without liquid egress or contamination ingress. This design from manufacturer neolab - Labor supports convenient media transfer, sampling or continuous-flow applications directly from GL45 bottles. Supplied as a single piece, the cap simplifies fluid-handling workflows in cell culture, chemistry and bioprocessing environments by combining secure closure with immediate tubing access. The open flow path without shut-off allows unrestricted passage once connected, making it ideal for gravity-feed or pump-assisted systems that require reliable venting and leak-free performance under routine laboratory conditions.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about neoChoice Schraubverschluss GL45 aus HDPE mit Schnellkupplung ohne Absperrung
What is this article?
neoChoice Schraubverschluss GL45 aus HDPE mit Schnellkupplung ohne Absperrung is the article on this page. Luminix Health distributes neolab 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.
