Description
Culture tubes, 20 x 180 mm, beaded rim provide larger-capacity glass vessels for cell culture, sample collection and microbiological applications. Fabricated from borosilicate glass 3.3, they deliver the chemical durability and thermal performance expected in routine laboratory practice. The beaded rim facilitates safe handling and stable placement in racks. Each pack contains 100 pieces, supporting efficient stock management in busy research or clinical environments. These culture tubes from manufacturer Witeg are made in Germany and carry a net weight of 3,608 kg per pack. With dimensions of 20 mm diameter by 180 mm length they accommodate greater sample volumes while remaining compatible with standard laboratory apparatus. Borosilicate glass 3.3 ensures low thermal expansion and resistance to thermal shock during heating or cooling steps. The tubes are suitable for media preparation, incubation and temporary storage of biological or chemical samples. Their clear glass walls allow easy visual inspection of contents. Laboratories rely on the consistent geometry and robust construction of these culture tubes for dependable daily use across varied experimental protocols.

Questions about Culture tubes 20 x 180 mm with rim
What is this article?
Culture tubes 20 x 180 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.
