Description
Test tubes 8 x 40 mm plain rim AR glass are compact laboratory vessels intended for sample handling, qualitative reactions and small-volume work. Each tube measures 8 x 40 mm, has a smooth plain rim and a round bottom, and is produced with a wall thickness of 0,8-1,0 mm from AR glass. The plain rim supports easy pouring, stoppering and cleaning, while the rounded base aids even heating and mixing of contents. Supplied in packs of 200 pieces, these tubes suit routine analytical chemistry, teaching laboratories, sample storage and general wet-chemistry workflows. Their compact format is practical when working with limited sample volumes or when rack and centrifuge space is constrained. These test tubes from manufacturer Witeg provide consistent dimensions for everyday laboratory procedures involving aqueous solutions, reagents and biological samples. AR glass construction offers suitable chemical resistance for standard laboratory conditions. The pack has a net weight of 0,212 kg and is well matched to educational demonstrations, preliminary screening tests and high-throughput sample preparation where economical, reliable glassware is required.

Questions about Test tubes, AR-glass, 0,8-1,0 mm thick,
What is this article?
Test tubes, AR-glass, 0,8-1,0 mm thick, 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.
