Description
Kahn tubes 75 x 12 mm AR glass are disposable culture and serological tubes manufactured from AR glass for routine laboratory use. Each tube measures 75 mm in length by 12 mm in diameter and features a smooth rim together with a round bottom, facilitating easy filling, mixing and centrifugation of liquid samples. Supplied in packs of 250 pieces, the tubes offer a practical format for high-throughput serological testing, sample storage and general culture work. The AR-glass composition provides good chemical resistance and optical clarity for visual inspection of contents. These Kahn tubes from manufacturer Witeg are intended for single-use applications in clinical, microbiological and analytical laboratories where consistent dimensions and reliable glass quality are required. The smooth rim reduces the risk of chipping during handling, while the round bottom supports uniform heating or cooling when placed in water baths or heating blocks. Net pack weight is approximately 0,978 kg, making the carton convenient to store and distribute within laboratory logistics systems.

Questions about Kahn-tubes AR-glass
What is this article?
Kahn-tubes AR-glass 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.
