Description
Labocap test tube caps 12/13 mm are aluminium culture caps for covering laboratory test tubes in microbiology, cell culture and general laboratory work. Made from high-quality aluminium in a red finish and supplied without a handle, they provide a rust-free, durable closure suited to everyday handling of culture tubes. The caps are heat-resistant and sterilizable, and can be washed with neutral detergent at temperatures up to 140 °C, supporting repeated cleaning and sterilization cycles while retaining their shape and function. Sized for 12/13 mm tubes, they serve as practical Kapsenberg-style aluminium covers that help protect contents during incubation and routine processing. Packed in boxes of 100 pieces from manufacturer Marienfeld, these Labocap caps offer a reusable aluminium option for research, teaching and quality-control laboratories that need reliable red test tube caps in a standardized diameter. Their robust metal construction combines corrosion resistance with thermal stability for consistent performance across common laboratory hygiene and culture workflows.

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.
