Description
Culture tubes, 20 x 100 mm with PP cap are compact glass vessels designed for cell culture, sample storage and microbiological work requiring a secure closure. Made of borosilicate glass and fitted with a two-position polypropylene cap, they are completely autoclavable for sterile applications. The two-position PP cap allows controlled gas exchange or tight sealing according to protocol needs. Offered as single pieces, these tubes suit flexible laboratory workflows and individual sample handling. Culture tubes from manufacturer Witeg originate in Germany and have a net weight of 0,018 kg each. Measuring 20 mm in diameter by 100 mm in length they fit common racks and incubators while providing convenient working volume. Borosilicate glass construction supplies the chemical resistance and clarity required for visual monitoring of cultures or samples. The fully autoclavable design supports repeated sterilisation cycles without compromising integrity. These tubes serve research, clinical and quality-control laboratories that need reliable, closable culture vessels for incubation, transport or short-term retention of biological materials under controlled conditions.

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