Description
Test tubes AR 12 × 100 mm GL 14 are screw-cap culture and sample tubes manufactured from AR glass with a wall thickness of 1 mm. Each tube measures 12 mm in diameter and 100 mm in height and is closed by a GL 14 screw cap fitted with a PE seal for reliable liquid retention. The pack contains 100 pieces, providing a convenient quantity for routine laboratory workflows. These tubes from manufacturer Witeg are suited to general chemical, biological and analytical applications where clear AR glass, chemical resistance and a secure threaded closure are required. The PE gasket ensures a tight seal during mixing, storage or transport of samples. With a net weight of 1,158 kg per pack, the set is ready for immediate use in research, quality-control and teaching laboratories that rely on standardised small-volume glassware with screw-thread convenience.

Questions about Test tubes AR 12 x 100 mm GL 14
What is this article?
Test tubes AR 12 x 100 mm GL 14 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.
