Description
Test tubes 12 x 100 mm NS 10/13 are compact laboratory glass tubes equipped with a standard ground joint NS 10/13 and matching NS-PE stoppers. Produced from DURAN tubing, these round-bottom, ungraduated vessels combine chemical resistance with thermal durability for routine sample work. Measuring 12 mm in diameter and 100 mm in length they are well suited to smaller sample volumes while the ground joint provides a secure closure with the polyethylene stopper. Supplied in packs of 10 pieces from manufacturer Witeg, the tubes serve sample handling, short-term storage, reactions and educational demonstrations in research and quality-control laboratories. The clear ungraduated design permits easy visual monitoring of contents and the round bottom supports gentle heating when required. These durable glass test tubes are a practical choice for chemistry, biology and general laboratory applications needing reliable small-format borosilicate glassware with NS joints.

Questions about Test tubes 12 x 100mm ST 10/13
What is this article?
Test tubes 12 x 100mm ST 10/13 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.
