Description
Test tubes "ELKA" featuring a beaded rim are robust soda-lime glass vessels intended for sample storage, mixing and qualitative laboratory procedures. Measuring approximately 200 mm in length with a generous 30 mm diameter, they offer increased capacity for larger sample volumes or multi-step reactions while retaining good handling characteristics. The soda-lime glass construction delivers clear visibility of contents together with suitable chemical resistance for aqueous solutions and many standard laboratory reagents. A reinforced beaded rim enhances durability, eases stopper insertion and reduces edge damage during frequent use. Available in packs of 50 pieces from manufacturer Hecht, the ELKA range supports teaching laboratories, routine analytical work and research settings that demand reliable, economical glass tubes. The wider bore facilitates easy filling, swirling and retrieval of solid or liquid samples. These dimensions fit common larger tube racks and heating blocks, making the product a practical choice for everyday wet-chemistry and sample-preparation tasks.

Questions about Test tubes ELKA, with rim mm Ø ca. 200 x 30
What is this article?
Test tubes ELKA, with rim mm Ø ca. 200 x 30 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.
