Description
Culture tubes 12 x 75 mm with beaded rim are compact laboratory tubes intended for small-volume cultures, sample collection and routine microbiological work. Manufactured from borosilicate glass 3.3 with a wall thickness of 0,9-1,0 mm and a round bottom, they combine chemical durability with thermal stability suitable for autoclaving and incubator use. The beaded rim strengthens the mouth of the tube and improves handling when fitting closures or transferring contents. Measuring 12 mm in diameter by 75 mm in length, these tubes fit standard racks and are well suited to limited sample volumes in research, teaching or diagnostic settings. Supplied in packs of 100 pieces, they provide a practical quantity for daily laboratory operations. These culture tubes from manufacturer Witeg deliver clear visibility of contents and consistent glass quality for reliable performance. Their robust construction supports centrifugation-compatible handling and repeated thermal cycles while maintaining the dimensional precision required for reproducible culture and sample-preparation protocols.

Questions about Culture tubes 12 x 75 mm with rim
What is this article?
Culture tubes 12 x 75 mm with rim 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.
