Description
Test tubes with beaded rim are thick-walled DURAN® laboratory vessels for everyday sample handling, with a nominal volume of 32 ml. Each tube combines a reinforced beaded rim for secure gripping and stopper seating with a robust thick wall that withstands routine mechanical stress during mixing, heating, and transfer steps. Offered as a pack of 100 pc(s), the set supports continuous use in teaching laboratories, research groups, and industrial quality-control environments. These DURAN® tubes from manufacturer DWK Life Sciences provide the optical clarity expected of laboratory glassware, so operators can monitor colour changes, precipitates, or phase separations at a glance. The thick-walled design is especially useful when tubes are repeatedly handled or lightly heated under standard laboratory practice. A complete pack weighs 2,500 kg, which simplifies inventory planning for central stores and bench stock. Whether used for qualitative tests, reagent aliquots, or temporary sample holding, these beaded-rim test tubes offer a dependable glass format that fits conventional racks and common laboratory accessories without special adapters.

Questions about Test tubes, beaded rim, DURAN®, thick walled, 32 ml, 100 unit(s)
What is this article?
Test tubes, beaded rim, DURAN®, thick walled, 32 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.
