Description
Aluminium push-on caps measuring 39x30 mm serve as reliable laboratory covers for test tubes and culture vessels. Fabricated from aluminium, these slip-on caps deliver a straightforward protective closure suitable for everyday microbiological and cell-culture work. Supplied in a pack of 10 pieces, they are ideal for laboratories that prefer smaller quantities or need to match specific tube diameters. These aluminium caps from manufacturer schuett biotec function as culture caps or Kapsenberg-style covers and are commonly used to shield samples during incubation, transport or temporary storage. The push-on design enables quick application and removal without screw threads, supporting efficient bench workflows. Durable aluminium construction ensures consistent handling performance. Measuring 39x30 mm, the caps are intended for compatible glassware formats in this size range and help maintain sample integrity in research and diagnostic settings where simple, effective covering is essential.

Questions about ALU-STECK-caps, 39x30 mm (qty=10)
What is this article?
ALU-STECK-caps, 39x30 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.
