Description
PP caps for culture tubes with Ø 25 mm are polypropylene closures designed for laboratory culture tubes of 25 mm diameter. They replace traditional cotton plugs and support reliable tube sterilisation workflows. The blue caps are sterilizable up to 121 °C, making them suitable for routine autoclave cycles used in microbiology and cell-culture preparation. Supplied in packs of 100 pieces from manufacturer LAT, these caps provide a practical, reusable alternative to loose stoppers when sealing culture tubes before or after sterilisation. Their polypropylene construction offers chemical resistance appropriate for standard laboratory media and cleaning regimes, while the defined fit for 25 mm tubes helps maintain consistent handling across batches. Ideal for culture-tube preparation, media sterilisation and general laboratory organisation, the caps simplify sealing steps and reduce reliance on cotton plugs. Use them wherever culture tubes of this diameter require a durable, heat-stable closure that withstands repeated sterilisation at 121 °C.
This article is part of Test tubes, in Tubes & vials.

Questions about Caps made of PP for culture tubes, for Ø, 25 mm
What is this article?
Caps made of PP for culture tubes, for Ø, 25 mm is the article on this page. Luminix Health distributes LAT for laboratory use. It sits in Test tubes, inside Tubes & vials, in Labware.
A test tube is the open cylindrical vessel for a small liquid, in borosilicate glass or in plastic. Rimmed and rimless mouths differ. The size is diameter by length. It is not graduated for a result, and a glass tube that will be centrifuged has a force limit.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
