Description
Test tubes, heavy-wall, with plain rim, made of soda-lime glass and measuring approximately 50 x 6-6,5 mm, are compact glass vessels intended for small-volume laboratory work. They feature a length of 50 mm and a diameter of 6 mm (range 6-6,5 mm) together with a plain rim and thicker wall construction. The soda-lime glass material (Kalk-Natron-Glas) is specified for these tubes, which are supplied in packs of 100 pc(s). Typical uses include micro-scale reactions, Durham-tube applications, Kahn or Coombs test procedures, blood-group examinations and other specialised small-volume assays referenced for this series. The heavy-wall design and short format suit insertion into compact racks or specialised holders while the plain rim allows straightforward filling and emptying. Produced by Hecht, the tubes fall within the reagent-tube and sample-tube categories and support precise handling of limited sample quantities in clinical, serological and general analytical settings. Clear glass enables direct visual monitoring of contents during testing protocols.
This article is part of Test tubes, in Tubes & vials.

What is this article?
Test tubes, heavy wall, rimless, soda lime glass mm Ø ca. 50 x 6-6,5 Nr. 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.
