Description
Test tubes AR 16 x 100 mm GL 18 are laboratory glass vessels made from AR glass with a wall thickness of 1 mm. Each tube measures 16 mm in diameter and 100 mm in height and is fitted with a GL 18 screw closure complete with PE gasket for reliable sealing. The pack contains 100 pieces, making these tubes practical for routine reagent handling, sample collection and short-term storage in analytical and research environments. Their standardised dimensions allow convenient placement in common test-tube racks while the AR glass construction provides the clarity and chemical resistance expected in everyday laboratory work. These tubes from manufacturer Witeg support a wide range of wet-chemistry and sample-preparation tasks where secure, reusable glass containers are required. The GL 18 thread ensures consistent closure performance and the integrated PE gasket helps maintain a tight seal during mixing or transport. Suitable for chemistry, biology and clinical laboratories, the tubes combine straightforward functionality with robust material quality for daily experimental workflows and organised sample management.

Questions about Test tubes AR 16 x 100 mm GL 18
What is this article?
Test tubes AR 16 x 100 mm GL 18 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.
