Description
Test tubes with beaded rim are thick-walled DURAN® laboratory tubes offered at a nominal capacity of 70 ml for everyday sample work in chemical, analytical and life-science laboratories. The beaded rim reinforces the tube mouth, improving grip during pouring, stoppering and transfer while helping the glass withstand routine handling. Thick-walled construction gives a solid, durable vessel suited to racks, heating blocks and general bench use without adding unnecessary complexity to the design. Each pack contains 50 pc(s), giving a practical working stock for teaching laboratories, quality-control benches and research groups that consume tubes regularly. The tubes are produced in DURAN® glass from manufacturer DWK Life Sciences and align with standard laboratory glassware expectations for clarity, cleanability and visual inspection of contents. Their straightforward cylindrical form fits common test-tube racks and holders used across wet-chemistry and sample-preparation workflows. These beaded-rim tubes serve qualitative tests, small-volume reactions, temporary holding of liquids and other routine procedures where a robust open tube is required. The pack is specified with a total weight of 2,000 kg, reflecting the substantial glass wall thickness of the full unit quantity. Intended for professional laboratory environments, the product sits within the test-tube and sample-tube segment of laboratory glass consumables.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, beaded rim, DURAN®, thick walled, 70 ml, 50 unit(s)
What is this article?
Test tubes, beaded rim, DURAN®, thick walled, 70 ml, 50 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.
