Description
Test tubes with beaded rim are thick-walled DURAN® laboratory vessels designed for general sample work, with a nominal volume of 40 ml. A reinforced beaded rim improves grip and stopper seating while the thick wall increases resistance to everyday mechanical stress during mixing, heating, and transfer. Packaged as 100 pc(s), the set is well suited to teaching labs, research groups, and industrial quality-control settings that consume glassware at a steady rate. From manufacturer DWK Life Sciences, these DURAN® tubes deliver clear optical performance so colour shifts, precipitates, and phase boundaries remain easy to observe. The robust wall profile supports repeated handling under normal laboratory practice and fits conventional test-tube racks and accessories. Total pack weight is 2,800 kg, which helps with inventory planning for central stores and bench replenishment. Ideal for qualitative assays, reagent aliquots, and temporary holding of liquid or solid samples, these beaded-rim tubes provide a dependable glass format for routine laboratory operations.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, beaded rim, DURAN®, thick walled, 40 ml, 100 unit(s)
What is this article?
Test tubes, beaded rim, DURAN®, thick walled, 40 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.
