Description
Test tubes in borosilicate glass 3.3, heavy-wall with plain rim, approx. 100 × 12 mm, provide versatile laboratory glassware for sample preparation, heating, mixing and general analytical work. With a length of approximately 100 mm and a diameter of 12 mm, they offer a practical mid-size format for routine wet-chemistry procedures and rack-based workflows. Borosilicate glass 3.3 combines thermal shock resistance with chemical durability against water, dilute acids, saline solutions and many organic solvents encountered in daily laboratory practice. The heavy-wall design improves mechanical robustness during handling and repeated use, while the plain smooth rim facilitates pouring and compatibility with standard closures. Available in packs of 100 pieces from manufacturer Hecht, these tubes support consistent batch processing in research, quality-control and teaching environments. The transparent glass body enables clear observation of reactions, colour shifts and phase boundaries. Approx. 100 × 12 mm dimensions suit small- to medium-volume samples and fit common test-tube racks and heating blocks. These heavy-wall borosilicate tubes are a dependable choice for laboratories needing durable, reusable glass consumables for everyday chemical and biological protocols.

Questions about Test tubes, borosilicate glass 3.3, heavy wall rimless mm Ø ca. 100 x12
What is this article?
Test tubes, borosilicate glass 3.3, heavy wall rimless mm Ø ca. 100 x12 is the article on this page. Luminix Health distributes Hecht 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.
