Description
Test tubes with straight rim are thick-walled DURAN® laboratory vessels with a nominal capacity of 70 ml. They address applications that need a larger open tube for sample mixing, heating or temporary liquid holding in research, teaching and quality-control settings. The straight rim simplifies pouring and insertion of pipettes or other tools and works with standard open-tube handling and closure habits. Thick-walled glass gives a robust format for frequent bench use and cleaning. This variant is supplied as 50 pc(s) per pack, a practical quantity for the 70 ml size in multi-user laboratories. The pack weight is 2,050 kg. Manufactured by DWK Life Sciences as part of the DURAN® range, the tubes fit established laboratory glassware and consumable programmes for chemistry, biology and general analytical work. Select the 70 ml straight-rim, thick-walled model when protocols call for greater working volume within the same DURAN® test-tube family used for smaller capacities elsewhere in the laboratory.
This article is part of Test tubes, in Tubes & vials.

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