Description
Test tubes 180 x 18 mm are round-bottom laboratory tubes with a straight rim made from soda-lime glass. Each tube features a wall thickness of 1,0 mm and provides a nominal volume of 35 ml while remaining ungraduated for versatile use. The 180 mm length and 18 mm diameter make these tubes practical for routine mixing, heating, qualitative reactions and temporary sample holding in chemical, biological and teaching laboratories. Clear soda-lime glass construction allows easy visual inspection of contents and precipitates. Packaged in cartons of 100 pieces, the tubes support efficient laboratory inventory and daily workflow. Produced by manufacturer Marienfeld, they fit standard test-tube racks and are suitable for general experimental work where precise graduation is unnecessary. The straight rim design permits simple covering or stoppering when required during procedures. These dimensions and the robust yet economical glass material address common needs in research, quality control and educational settings for reliable sample handling.

Questions about Test tubes 180x18 mm,
What is this article?
Test tubes 180x18 mm, is the article on this page. Luminix Health distributes Marienfeld 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.
