Description
Screw caps made of PBT in red are laboratory closures with a GL 14 thread, measuring Ø 20 × H 17 mm for matching glassware and bottles that use this standard neck finish. Polybutylene terephthalate (PBT) gives a durable, dimensionally stable cap body suitable for repeated opening and closing in everyday lab use. The bright red colour supports quick visual identification of sealed vessels on crowded benches or in storage. Packaged as 10 pieces with a total weight of 0,040 kg, the set covers routine replacement and multi-vessel setups. These screw caps from manufacturer DWK Life Sciences belong with laboratory glass, vessels and consumables where reliable seals, hose connectors and related accessories are required. GL 14 compatibility ensures straightforward pairing with correspondingly threaded bottles, flasks and tubes used in sample storage, reagent handling and general wet-chemistry work. Compact external dimensions keep the closure profile neat while still providing a secure screw engagement. Laboratories standardising on red PBT caps can maintain a consistent appearance across GL 14 containers and simplify stock management for seals used throughout liquid-handling and storage workflows.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps made of PBT, red, GL 14, Ø 20 x H 17 mm, 10 unit(s)
What is this article?
Screw caps made of PBT, red, GL 14, Ø 20 x H 17 mm, 10 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.
