Description
Culture tubes 12 x 75 mm straight rim are laboratory tubes manufactured from borosilicate glass 3.3 for general culture and sample-handling work. Each tube measures 12 x 75 mm, features a straight rim, a round bottom and a wall thickness of 0,9-1,0 mm, providing a robust yet clear vessel suitable for routine microbiological and chemical procedures. The borosilicate glass 3.3 composition offers the thermal and chemical resistance expected of this glass type in everyday laboratory use. Supplied in packs of 100 pieces from manufacturer Witeg, the tubes arrive ready for standard culture, incubation or storage applications where a straight-rim format is preferred. Net weight of the pack is 0,562 kg. These dimensions and the round-bottom geometry support stable placement in racks and even heating when required. The straight rim facilitates straightforward capping or plugging according to laboratory protocol. Intended for research, teaching and quality-control environments, the tubes form a basic consumable for holding liquid or solid media and samples under typical laboratory conditions without additional specialised coatings or treatments.
This article is part of Test tubes, in Tubes & vials.

Questions about Culture tubes 12 x 75 mm plain top
What is this article?
Culture tubes 12 x 75 mm 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.
