Description
Test tubes 150 x 16 mm are ungraduated laboratory vessels made from borosilicate glass 5.1. They are supplied with a straight rim, round bottom, wall thickness of 0,7 mm and a nominal volume of 23 ml, measuring 150 mm in length and 16 mm in diameter. These tubes serve reliably for sample collection, reagent reactions, heating steps and general analytical procedures in chemical, biological and educational laboratories. The round bottom aids complete mixing and drainage, while the straight rim allows convenient sealing or covering during storage or incubation. Uniform glass quality and wall thickness contribute to good chemical durability and thermal performance under standard laboratory conditions. Available in cartons of 1000 pieces from manufacturer Marienfeld, they provide an economical packing unit for busy laboratory settings. The ungraduated format keeps the tubes versatile for qualitative work and sample preparation where volume graduation is not essential, supporting smooth daily workflows across diverse experimental protocols.

Questions about Test tubes 150x16 mm,
What is this article?
Test tubes 150x16 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.
