Description
DURAN® test tube with beaded rim is a thick-walled laboratory vessel for heating small substance quantities, performing preliminary tests, reaction controls and test series, and for storage or transport of small liquid volumes. Manufactured from borosilicate glass 3.3, it offers high mechanical resistance, a round bottom and a permanently fired white printed marking that remains durable in daily use. The beaded rim reinforces the opening and supports secure handling during routine laboratory workflows. With a nominal volume of 100 ml and dimensions of 30 mm diameter by 200 mm length, the tube is suited to converting substances and liquids into other aggregate states to initiate further reactions. Available in packs of 50 pieces from manufacturer Duran/DWK Life Sciences, these tubes serve analytical and preparative tasks that demand reliable thermal and chemical performance. Thick walls, round-bottom geometry and clear permanent labelling ensure consistent usability across repeated heating and observation cycles in research, teaching and quality-control environments.

Questions about DURAN® Test Tube, with beaded rim
What is this article?
DURAN® Test Tube, with beaded rim 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.
