Description
Premium screw caps made from TPCh260 with thread 45 are laboratory closures sized for compatible bottle necks, offering an outer diameter of 51 mm and a height of 26 mm. These dimensions support secure seating on vessels that share the same thread geometry, helping maintain a reliable seal during routine handling, storage and transfer of samples or reagents. Each pack contains 5 pc(s) and has a total weight of 0,165 kg, making the set practical for bench stocking without excess bulk. The caps belong to the premium accessory range associated with manufacturer DWK Life Sciences and align with laboratory glass, vessels and consumables workflows that rely on standardised screw closures. Within container, bottle and seal assemblies, TPCh260 construction provides a defined material choice for matching existing fleets of laboratory bottles. Users can select these premium screw caps as replacement or complementary closures wherever thread 45 and the stated diameter and height are required. The compact five-piece unit quantity suits quality-control, research and teaching laboratories that need consistent sealing components for everyday bottle work, while the clear dimensional data simplifies cross-checking against current bottle inventories and accessory lists.

Questions about Premium screw caps, TPCh260, thread 45, Ø 51 mm, H 26 mm, 5 unit(s)
What is this article?
Premium screw caps, TPCh260, thread 45, Ø 51 mm, H 26 mm, 5 unit(s) 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.
