Description
Test tubes 180 x 18 mm are round-bottom laboratory tubes made from soda-lime glass for sample preparation, reactions and general laboratory use. Measuring 180 mm in length and 18 mm in diameter, they offer a nominal volume of 35 ml and a wall thickness of 0,8 mm. A beaded rim improves handling safety and durability at the open end, while the round bottom assists even heating and thorough mixing of contents. These tubes from manufacturer Marienfeld are packed in cartons of 100 pieces, with a minimum order quantity of 1,000 pieces, suiting facilities that process larger batches of glassware. Soda-lime glass provides dependable everyday chemical resistance for many aqueous and organic media typical of teaching, quality-control and research laboratories. The larger 180 x 18 mm format accommodates higher sample volumes while remaining compatible with standard racks and heating equipment. Consistent geometry and economical carton packaging deliver a practical solution for laboratories seeking reliable, high-volume soda-lime glass test tubes without specialised coatings or borosilicate requirements.

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.
