Description
Test tubes, heavy-wall, with plain rim, soda-lime glass, approximately 180 mm in length and 18 mm in diameter, provide robust vessels for general laboratory sample work, mixing and simple reactions. Constructed from soda-lime glass in a heavy-wall design with a plain rim, they deliver enhanced mechanical strength for routine handling in chemistry, biology and clinical settings. The larger 18 mm diameter and 180 mm length offer greater working volume than smaller tubes while remaining compatible with standard racks and holders. These tubes from manufacturer Hecht are well suited to heating in water baths or blocks, temporary storage of liquids and solids, and everyday qualitative procedures where durable glassware is preferred. The plain rim facilitates pouring, cleaning and the use of appropriate closures. Supplied in a pack of 100 pieces and originating from Germany, they form a practical bulk option for laboratories that regularly consume soda-lime glass test tubes of this size. The heavy-wall construction supports repeated use under normal laboratory conditions without unnecessary fragility.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, heavy wall, rimless, soda lime glass mm Ø ca. 180 x18 Nr. 42775009
What is this article?
Test tubes, heavy wall, rimless, soda lime glass mm Ø ca. 180 x18 Nr. 42775009 is the article on this page. Luminix Health distributes Hecht 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.
