Description
Culture tubes 20 x 150 mm with PP cap are borosilicate glass vessels intended for microbiological, bacteriological and routine cell-culture work in research and clinical laboratories. With a diameter of 20 mm and a length of 150 mm they provide a practical working volume for media preparation, inoculation, incubation and short-term sample holding. Each tube is fitted with a two-position polypropylene (PP) cap that can be left loosely seated to allow controlled gas exchange or pressed fully home for a secure, contamination-resistant seal. The complete assembly of glass tube and PP cap is fully autoclavable, supporting repeated steam-sterilisation cycles without loss of dimensional stability or optical clarity. These culture tubes from manufacturer Witeg combine the chemical resistance and thermal-shock tolerance of quality borosilicate glass with a convenient closure system suited to everyday laboratory workflows. Clear walls permit easy visual inspection of cultures, while the standardised dimensions ensure compatibility with common racks, baskets and incubators. Supplied as single pieces with a net weight of 0,02 kg, they integrate readily into existing glassware inventories for bacteriology, mycology, teaching laboratories and general culture protocols.

Questions about Culture test tubes borosilcate glass
What is this article?
Culture test tubes borosilcate glass 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.
