Description
Aluminium push-on caps measuring 17x30 mm provide secure, reusable closures for test tubes, culture tubes and similar laboratory glassware. These aluminium caps function as classic Kapsenberg-style or culture caps, offering a snug push-on fit that protects samples from contamination while permitting limited gas exchange during incubation or storage. Fabricated from durable aluminium, they withstand typical laboratory conditions including autoclaving cycles and exposure to common reagents. Supplied in a practical pack of 100 pieces from manufacturer schuett biotec, the caps suit routine work in microbiology, cell culture, clinical diagnostics and general research laboratories. The 17x30 mm format matches widely used tube diameters, ensuring reliable seating without additional fasteners. Lightweight yet robust construction supports repeated handling and cleaning, helping maintain consistent workflow efficiency. Their simple design reduces the risk of cross-contamination compared with loose plugs or foil, making them a standard accessory for sample protection and short- to medium-term culture maintenance across many laboratory environments.

Questions about ALU-STECK-caps, 17x30 mm (qty=100)
What is this article?
ALU-STECK-caps, 17x30 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.
