Description
Replacement screw-cap closures, 28 mm are laboratory consumables intended for plastic bottles and related vessels used in routine lab handling and storage. These closures serve as dedicated replacement caps for matching 28 mm bottle necks within standard container systems. They support continued use of existing bottles when original caps need renewal, helping maintain organised workflows for liquids and samples in research, quality control and general laboratory environments. The pack contains 100 pc(s), giving laboratories a practical stock quantity for everyday replenishment. Overall pack weight is 0,400 kg, which keeps the unit easy to store and distribute across workstations or central stores. Produced by manufacturer KAUTEX, the closures align with common labware formats for containers, bottles, tins and canisters. They sit within the plastic-bottle accessory range and are suited to laboratories that standardise on 28 mm screw-neck vessels. Use them to keep bottle systems operational for preparation, intermediate storage and transport steps without replacing entire containers when only the closure is required.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Replacement screw-cap closures, 28 mm, 100 unit(s)
What is this article?
Replacement screw-cap closures, 28 mm, 100 unit(s) is the article on this page. Luminix Health distributes KAUTEX 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.
