Description
Aluminium push-on caps 12x25 mm are lightweight aluminium closures supplied in packs of 100 pieces for laboratory tube covering. These caps serve as practical covers for test tubes, culture tubes and similar vessels, functioning in the style of Kapsenberg or culture caps used in microbiological and general laboratory work. The aluminium material offers a simple push-fit solution that helps shield contents from dust and airborne contamination while remaining easy to apply and remove. Measuring 12x25 mm, the dimensions suit corresponding tube diameters for a secure seating without threads. From manufacturer schuett biotec, the ALU push-on caps support routine sample protection and organisation tasks in research, teaching and quality-control laboratories. They are commonly employed in bacteriology workflows, culture handling and everyday wet-lab operations where rapid capping is advantageous. The aluminium construction is robust yet light, facilitating convenient handling in high-throughput settings. Supplied as 100 pieces per pack, the set meets the needs of multi-user benches and larger experimental series. These push-on aluminium caps provide a straightforward, reusable or disposable covering option for standard laboratory glassware and plastic tubes of matching size.

Questions about ALU-STECK-caps, 12x25 mm (qty=100)
What is this article?
ALU-STECK-caps, 12x25 mm (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.
