Description
Test tube 30 x 250 mm GL32 sterilisable is a laboratory glass tube made from borosilicate glass and delivered complete with screw thread, cap and seal. It measures 250 mm in length and 30 mm in diameter, uses a GL 32 thread and incorporates a thick-walled writing field for reliable sample marking. The entire assembly is completely sterilisable, allowing repeated sterilisation cycles under normal laboratory conditions. These tubes from manufacturer Witeg are supplied as single pieces and function as sample tubes, reaction tubes and general laboratory vessels. Borosilicate glass together with the screw-cap and seal arrangement offers a practical closed format for sample and reagent handling. The strong labelling field supports clear identification during laboratory procedures. Intended for research, quality-control and educational settings, the 30 x 250 mm GL32 size provides additional working volume compared with shorter formats while retaining the same sterilisable threaded closure. Consistent geometry and complete supply with cap and seal make the tubes straightforward to integrate into routine laboratory glassware inventories.

Questions about Test tubes, boro., screw thread, w. cap
What is this article?
Test tubes, boro., screw thread, w. cap 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.
