Description
Labocap Closure Aluminium 12-13 mm is an aluminium laboratory closure designed for culture glasses with a neck diameter of 12–13 mm. This Labocap aluminium seal is used to close culture vessels in microbiology, cell-culture preparation and general laboratory workflows where a reliable aluminium crimp-style cap is required. The aluminium body matches culture-glass necks in the 12–13 mm range and supports secure sealing of media, cultures and samples during routine handling and incubation. Available as a pack of 105 pieces from manufacturer Witeg, the product is practical for laboratories running multiple culture glasses side by side. Each unit has a net weight of 0,003 kg and a gross weight of 0,003 kg, consistent with a compact aluminium closure. These Labocap items are grouped with laboratory closure caps, aluminium caps and crimp caps for culture glassware. They suit research, quality-control and teaching laboratories that standardise on aluminium Labocap closures for 12–13 mm neck formats. The design supports everyday sealing tasks on culture glasses while remaining straightforward to integrate into existing laboratory sealing procedures.

Questions about Labocap-Closures Alu 12-13
What is this article?
Labocap-Closures Alu 12-13 is the article on this page. Luminix Health distributes Witeg 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.
