Description
ELKA test tubes with beaded rim are classic laboratory glassware for sample preparation, qualitative analysis and general chemical work. These tubes measure approximately 160 mm in length with a diameter of 16 mm and feature a reinforced beaded rim that improves mechanical stability and handling safety. Manufactured from soda-lime glass, they provide clear visibility of contents and adequate chemical resistance for many aqueous and mild organic applications under standard laboratory conditions. The pack of 200 pieces from manufacturer Hecht supports high-throughput routines in research, teaching and industrial quality-control laboratories. Compatible with common test-tube racks, holders and heating devices, the 160 × 16 mm format is a widely used size for reaction monitoring, precipitation tests and temporary storage of liquid or solid samples. The beaded rim design also facilitates secure placement of stoppers or cotton plugs when required. These ELKA tubes offer a practical, economical solution for everyday wet-chemistry tasks where reliable glass performance is essential.

Questions about Test tubes ELKA, with rim mm Ø ca. 160 x 16
What is this article?
Test tubes ELKA, with rim mm Ø ca. 160 x 16 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.
