Description
Test tubes with beaded rim are thick-walled DURAN® laboratory glass vessels intended for small-volume sample work, qualitative assays and routine visual inspection in teaching, analytical and research laboratories. Each tube has a nominal capacity of 5 ml and a beaded rim that strengthens the mouth, aids handling and supports compatible stoppers or covers when needed. Thick-walled DURAN® glass gives a sturdy body for repeated heating, cooling and mechanical use, while optical clarity allows easy monitoring of colour changes, turbidity and phase separation. The articles are supplied in a pack of 100 pieces with a total weight of 0,610 kg, making them practical for multi-user benches, course kits and central glassware stores. These tubes from manufacturer DWK Life Sciences fit standard small-format racks and holders and integrate smoothly into established sample-preparation and screening procedures. They suit general chemistry, biology and quality-control tasks that require reliable, reusable glass test tubes with a beaded rim and a 5 ml working volume.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, beaded rim, DURAN®, thick walled, 5 ml, 100 unit(s)
What is this article?
Test tubes, beaded rim, DURAN®, thick walled, 5 ml, 100 unit(s) 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.
