Description
LABOCAP caps without handle, 17/18 mm, silver are aluminium cover caps designed as test tube caps and culture caps. These Kapsenberg-style aluminium caps accommodate tubes of 17/18 mm diameter and feature a handle-free profile for compact seating. The silver finish offers a neutral appearance that integrates easily into standard laboratory colour schemes. Each pack contains 100 pieces. Manufactured by schuett biotec, the caps form part of the LABOCAP range of aluminium Abdeckkappen used for securing culture tubes and reagent tubes. The aluminium material delivers a lightweight yet durable closure suitable for everyday laboratory handling and sample organisation. Absence of a handle permits efficient stacking and storage of capped tubes while still providing reliable coverage. These silver LABOCAP caps without handle serve as practical accessories in microbiology, cell-culture and general analytical settings that require consistent, aluminium tube closures sized for the 17/18 mm range.

Questions about LABOCAP-caps without handle, 17/18 mm, silver (qty=100)
What is this article?
LABOCAP-caps without handle, 17/18 mm, silver (qty=100) is the article on this page. Luminix Health distributes Schuett-Biotec 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.
