Description
Labocap aluminium closure 19-20 mm is an aluminium sealing cap for culture glasses with a neck diameter of 19–20 mm. This Labocap closure is manufactured from aluminium and fits culture glass necks in the 19–20 mm range, providing a metal crimp-style cap for laboratory culture glassware. Net weight is 0,005 kg, so the aluminium construction remains light and practical for everyday handling when sealing culture vessels. The item forms part of the Labocap family of aluminium closures (Alukappen / Bördelkappen) specified for culture glasses and is sized expressly for the 19–20 mm neck-Ø. From manufacturer Witeg, the Labocap aluminium closure is suited to culture bottles and comparable glass containers that require this neck dimension. Laboratories can choose this variant when their culture glass inventory calls for a 19–20 mm aluminium Labocap seal. Unit quantity is 1 pc, enabling flexible replenishment next to other Labocap aluminium closures covering adjacent neck diameters. Country of origin is Switzerland. Only the aluminium material, neck fit and culture-glass application given by the manufacturer are stated here.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Labocap-Closures Alu 19-20
What is this article?
Labocap-Closures Alu 19-20 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.
