Description
Aluminium push-on caps measuring 44x40 mm provide secure covering for larger test tubes and culture vessels in the laboratory. Constructed from aluminium, these slip-on caps offer a practical protective closure for samples and cultures during handling, incubation or short-term storage. The pack of 10 pieces suits laboratories requiring moderate quantities matched to this diameter. These aluminium caps from manufacturer schuett biotec are typically employed as culture caps or Kapsenberg-style covers and fit corresponding glassware formats. Their aluminium build supports repeated use with straightforward push-on application and removal, eliminating the need for threaded closures. Gross weight of the pack is 0,16 kg, making the units easy to store and distribute. Ideal for reagent-tube and culture-vessel protection in microbiology, cell-culture and general laboratory environments, the 44x40 mm size expands the range of compatible vessels while maintaining simple, reliable covering performance.

Questions about ALU-STECK-caps, 44x40 mm (qty=10)
What is this article?
ALU-STECK-caps, 44x40 mm (qty=10) 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.
