Description
Culture tubes, 25 x 200 mm, straight rim are laboratory vessels manufactured from borosilicate glass 3.3 for reliable sample handling and cultivation work. Each tube measures 25 mm in diameter and 200 mm in length and is finished with a straight rim that supports secure capping or plugging during incubation and storage. The borosilicate glass 3.3 composition delivers the chemical resistance and thermal stability required for routine heating, autoclaving cycles and exposure to common culture media. Packaged as 50 pieces, the set provides a practical quantity for microbiology, cell-culture and general laboratory workflows where consistent tube geometry is essential. These culture tubes from manufacturer Witeg integrate easily into standard racks and heating blocks, enabling efficient parallel processing of multiple samples. With a pack net weight of 1,8 kg they remain convenient to store and transport while maintaining dimensional uniformity across the batch. The straight-rim design further simplifies labelling and visual inspection of contents under laboratory lighting conditions.
This article is part of Test tubes, in Tubes & vials.

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.
