Description
Test tubes with straight rim are thick-walled laboratory vessels in DURAN® glass with a nominal capacity of 34 ml. They are intended for everyday sample handling, mixing, heating and short-term holding of liquids in research, teaching and quality-control laboratories. The straight rim supports convenient pouring and straightforward use with common laboratory closures where a simple open-tube format is preferred. Thick-walled construction gives a sturdy feel for routine bench work and repeated washing cycles compared with thinner glassware of similar volume. These tubes are supplied as a pack of 100 pc(s), a practical unit quantity for stocking multi-user labs and high-throughput workflows. The pack weight is 2,300 kg, consistent with the solid glass build. Produced by manufacturer DWK Life Sciences under the DURAN® line, the tubes sit naturally within standard laboratory glass, vessel and consumable programmes for chemistry, life sciences and general analytical sample preparation. They suit protocols that call for a robust, straight-rim test tube at the 34 ml working volume without specialised joint or rim geometry.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, straight rim, DURAN®, thick walled, 34 ml, 100 unit(s)
What is this article?
Test tubes, straight rim, DURAN®, thick walled, 34 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.
