Description
Test tubes 180 x 18 mm with plain rim are standard laboratory glassware for sample handling, heating and routine chemical work. Each tube measures 180 mm in length and 18 mm in diameter, with a wall thickness of 0,8–1,0 mm and a round bottom that supports even heat distribution and thorough mixing. Manufactured from AR glass, they deliver the transparency and chemical durability required for everyday analytical, educational and quality-control procedures. The smooth plain rim facilitates easy pouring and accommodates stoppers when temporary closure is needed. Supplied in practical packs of 100 pieces from manufacturer Witeg, these tubes fit conventional racks, heating blocks and water baths. Their consistent geometry ensures reliable performance across multi-sample experiments in research, teaching and industrial laboratories. AR-glass construction provides a cost-effective balance of mechanical strength and chemical resistance for aqueous and many organic media. Ideal for qualitative analysis, culture work, temporary storage and general reaction vessels where moderate thermal and chemical demands apply.

What is this article?
Test tubes, 180 x 18 mm, without rim, 0 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.
