Description
LABOCAP caps without handle, 17/18 mm, red are aluminium cover caps intended for laboratory test tubes and culture tubes. These Kapsenberg-style caps serve as practical closures for reagent glasses and culture vessels in microbiological work as well as general laboratory routines. Made of aluminium in a distinctive red finish, the LABOCAP caps without grip enable straightforward colour-coded identification when handling multiple samples side by side and are sized for tubes of 17/18 mm diameter. Supplied in packs of 100 pieces from manufacturer schuett biotec, they support everyday covering of tubes during incubation, short-term storage or sample transfer. The aluminium material provides a robust yet lightweight construction suited to repeated laboratory handling, while the handle-free design maintains a compact profile that fits standard racks and incubators. Colour coding with the red variant helps organise cultures or reagents efficiently alongside other LABOCAP colours. These culture and test-tube caps protect contents from airborne contamination in routine workflows and match common glassware dimensions of 17/18 mm for reliable seating. Laboratories use them for consistent tube covering across analytical, culture and storage applications where simple aluminium caps are preferred.

Questions about LABOCAP-caps without handle, 17/18 mm, red (qty=100)
What is this article?
LABOCAP-caps without handle, 17/18 mm, red (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.
