Description
Tamper-evident screw cap closures, blue are laboratory sealing components designed for secure closure of compatible EH bottles with a 32 thread. Manufactured from polypropylene (PP) in a tall profile and supplied in blue, these caps provide a clear visual indication of first opening, supporting sample integrity and controlled access in routine laboratory workflows. The tamper-evident design is suited to storage of reagents, intermediates and prepared solutions where documented or visible seal status is required. A pack contains 10 pc(s) with a total weight of 0,088 kg, convenient for stocking preparation benches, media rooms and chemical storage areas. These closures from manufacturer DWK Life Sciences match tall EH bottle systems with thread 32 and help maintain a reliable seal during handling, transport within the lab and short- to medium-term storage. Blue colouring aids quick visual identification among mixed closure inventories. They support organised laboratory practice for solvents, standards and other liquids that benefit from a secure, tamper-evident PP screw closure on matching glass bottles.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Tamper-evident screw cap closures, blue, 32 thread, tall, for EH bottles, PP
What is this article?
Tamper-evident screw cap closures, blue, 32 thread, tall, for EH bottles, PP 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.
