Description
Test tubes 12 x 75 mm plain rim AR glass are standard laboratory vessels designed for sample handling, qualitative reactions, moderate-volume heating and short-term storage of liquids or solids. Each tube measures 12 x 75 mm, incorporates a smooth plain rim and round bottom, and is made with a wall thickness of 0,8-1,0 mm from AR glass. The plain rim enables straightforward pouring, stoppering and cleaning, while the rounded base supports even heat transfer and mixing. Supplied in packs of 100 pieces, these tubes are appropriate for analytical chemistry, teaching laboratories, quality-control work and general wet-chemistry procedures. The 12 x 75 mm size is a widely used format that fits common test-tube racks and accommodates typical sample volumes encountered in routine laboratory practice. These test tubes from manufacturer Witeg offer consistent geometry for everyday experimental workflows involving aqueous solutions, reagents and biological materials. AR glass construction provides suitable chemical resistance under standard laboratory conditions. The pack net weight is 0,572 kg, making the product practical for educational demonstrations, research screening and high-throughput sample preparation.

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.
