Description
Test tubes 18 x 180 mm GL 18 DURAN are high-quality laboratory tubes produced from DURAN borosilicate glass 3.3 tubing. They incorporate a DIN thread GL 18 complete with screw closure and silicone/PTFE gasket, ensuring a secure seal for sample containment, incubation or reaction work. The larger 18 mm diameter and 180 mm length offer increased working volume while retaining the thermal and chemical resistance characteristic of borosilicate glass 3.3. Ideal for general laboratory applications including sample preparation, media handling and analytical procedures, these tubes deliver consistent dimensions and reliable performance. Packaged in units of 50 pieces, they are ready for use in research, industrial or educational settings. Manufactured by Witeg, the DURAN test tubes combine proven glass quality with practical screw-cap convenience for everyday laboratory operations requiring durable, reusable glassware.

Questions about Test tubes 18 x 180 mm GL 18 DURAN
What is this article?
Test tubes 18 x 180 mm GL 18 DURAN 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.
