Description
Test tubes without beaded rim, volume 43 ml and dimensions Ø 20 × 200 mm, are straight-sided laboratory glassware intended for sample holding, mixing and general wet-chemistry work. Manufactured from neutral glass type LBG N, each tube offers a smooth open rim without a beaded edge, which simplifies cleaning, racking and insertion into heating blocks or water baths. The 43 ml working volume suits aliquots, qualitative tests and intermediate storage of aqueous or organic solutions in teaching and research laboratories. A pack of 100 pieces supports high-throughput workflows where disposable or frequently replaced glassware is preferred. Neutral glass construction provides the chemical resistance expected for routine reagents and buffers under ambient laboratory conditions. These tubes from manufacturer Labbox fit standard test-tube racks and centrifuges designed for the 20 mm diameter format. Clear cylindrical walls allow visual inspection of colour changes, precipitates and phase separation during experiments. Ideal for chemistry, biology and quality-control benches that require consistent geometry and a plain rim profile for everyday sample processing.

Questions about Test tube without rim, vol. 43 ml, Ø20x200 mm, Normal Glass LBG N, 100 pcs
What is this article?
Test tube without rim, vol. 43 ml, Ø20x200 mm, Normal Glass LBG N, 100 pcs is the article on this page. Luminix Health distributes Labbox 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.
