Description
Screw cap GL 70 with bore provides a practical closure for laboratory bottles and vessels fitted with a GL 70 thread when open access through the lid is required. A central bore of 58 mm diameter accommodates tubing, probes, sensors or other inserts while the cap stays firmly engaged on the neck. The grey polypropylene construction offers a lightweight, chemically resistant solution suitable for many aqueous and organic laboratory applications. Supplied as one piece from manufacturer Witeg, this screw cap is intended for media bottles, storage vessels and process setups that need a large central opening without compromising a secure GL 70 seal. The defined bore geometry and durable PP material support sampling, continuous reagent addition and instrument integration on GL 70 glassware. Net weight is 0,2 kg per piece, reflecting a solid yet easy-to-handle design for routine laboratory use.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps GL 70 top with hole
What is this article?
Screw caps GL 70 top with hole is the article on this page. Luminix Health distributes Witeg 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.
