Description
Culture tubes, 20 x 180 mm, straight rim provide larger-capacity glassware for extended culture volumes, media storage and sample processing in microbiology and cell-biology laboratories. Fabricated from borosilicate glass 3.3, they exhibit excellent resistance to chemicals and thermal stress, allowing safe autoclaving and repeated thermal cycling. The straight rim design enables easy closure with stoppers or caps and facilitates thorough cleaning. With a diameter of 20 mm and length of 180 mm, these tubes accommodate greater sample volumes while remaining compatible with standard racks and incubators. Each pack contains 100 pieces, supporting efficient stock management in busy research or diagnostic environments. These culture tubes from manufacturer Witeg offer the optical transparency required for visual inspection of cultures together with the mechanical durability needed for routine handling. Ideal for bacterial enrichment, yeast cultivation and general laboratory incubation workflows, they maintain dimensional accuracy and glass integrity throughout repeated use cycles in controlled laboratory settings.

Questions about Culture tubes plain top
What is this article?
Culture tubes plain top is the article on this page. Luminix Health distributes Witeg 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.
