Description
DURAN® test tube with beaded rim is a thick-walled laboratory vessel fabricated from borosilicate glass 3.3. With dimensions of 13 mm diameter by 100 mm length and a nominal volume of 9 ml, it suits handling of small substance quantities in daily laboratory practice. The tube features a round bottom and a permanently durable white print fired into the glass surface. Its thick walls deliver excellent mechanical resistance, making the vessel particularly robust during repeated use. Converting substances and liquids into other aggregate states and initiating subsequent reactions is central to laboratory workflows; reaction controls, test series and preliminary samples are typically performed in test tubes because only minimal sample volumes are required. Applications include heating of small amounts, preliminary testing, storage and transport of limited liquid volumes. This DURAN® model from manufacturer Duran/DWK Life Sciences comes with a beaded rim that improves handling and pouring. The pack contains 100 pieces for use in chemical, pharmaceutical and research environments requiring reliable glassware.
This article is part of Test tubes, in Tubes & vials.

Questions about DURAN® Test Tube, with beaded rim
What is this article?
DURAN® Test Tube, with beaded rim is the article on this page. Luminix Health distributes DWK Life Sciences 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.
