Description
Labocap test tube caps 12/13 mm are aluminium culture caps for covering standard laboratory test tubes in microbiology, cell culture and general sample handling. Made from high-quality aluminium in a blue finish, they are heat-resistant, rust-free and sterilizable, and can be washed with neutral detergent at temperatures up to 140 °C. The handle-free design gives a compact profile that fits tubes in the 12/13 mm diameter range and supports repeated use under routine laboratory conditions. Packed in boxes of 100 pieces, these caps from manufacturer Marienfeld provide a durable metal alternative to disposable closures for culture work, short-term incubation and tube protection. Aluminium construction combines mechanical strength with thermal stability, suiting autoclave cycles and cleaning protocols without corrosion. Suitable for research, teaching and quality-control laboratories that need consistent, reusable Kapsenberg-style covers without plastic components, they help maintain clean tube openings while remaining easy to place and remove during daily workflows.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Test tube caps Labocap 12/13 mm,
What is this article?
Test tube caps Labocap 12/13 mm, is the article on this page. Luminix Health distributes Marienfeld 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.
