Description
Culture tubes, 30 x 200 mm, beaded rim are laboratory glassware items intended for culture work, reagent handling and sample preparation. Manufactured from borosilicate glass 3.3, they combine a clear glass body with a beaded rim that strengthens the tube opening for secure day-to-day handling. Supplied in packs of 50 pieces from manufacturer Witeg, these tubes provide a practical format for laboratories that need larger-diameter culture vessels of fixed length. Measuring 30 mm in diameter and 200 mm in length, they accommodate culture media and samples in microbiological and chemical applications. The pack net weight is 2,964 kg. Laboratories employ them as culture tubes, reagent tubes or sample tubes across research, quality-control and educational settings. Transparency of the borosilicate glass supports easy visual checks of contents during incubation or storage. The defined dimensions and beaded rim allow straightforward integration into standard tube racks and routine laboratory workflows.

What is this article?
Culture tubes, with rim, 30 X 200 mm, b 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.
