Description
Test tubes with straight rim, DURAN®, thick walled, 4 ml are compact laboratory glass vessels for routine sample handling, qualitative tests and small-volume work. The straight rim supports straightforward filling, pouring and cleaning, while the thick-walled construction adds mechanical robustness for everyday bench use, transport in racks and repeated handling. A nominal capacity of 4 ml suits teaching experiments, quick checks and limited sample volumes where an open-top tube is preferred. These tubes are supplied as a pack of 100 pc(s) from manufacturer DWK Life Sciences, giving laboratories a practical stock unit for teaching, quality control and research workflows. DURAN® glassware is valued for clarity that aids visual inspection of contents and for reliable performance in standard laboratory environments. The pack has a stated weight of 0,465 kg, which is convenient for storage and internal logistics. Suitable for chemistry, life-science and general analytical settings that require simple, durable test tubes without specialised closures, they integrate easily with common racks and holders used across the lab.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, straight rim, DURAN®, thick walled, 4 ml, 100 unit(s)
What is this article?
Test tubes, straight rim, DURAN®, thick walled, 4 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.
