Description
Test tubes in borosilicate glass 3.3, heavy-wall with plain rim, approx. 130 × 14 mm, are robust laboratory glassware intended for sample handling, heating, mixing and general chemical work. Measuring approximately 130 mm in length and 14 mm in diameter, they provide a larger working volume than shorter formats while remaining compatible with standard racks and laboratory fixtures. Borosilicate glass 3.3 delivers strong thermal shock resistance and reliable chemical durability toward water, dilute acids, saline media and many organic solvents used in routine analysis. The heavy-wall construction enhances mechanical strength for frequent handling, and the plain smooth rim supports clean pouring as well as the use of common stoppers or caps. Packaged as 100 pieces from manufacturer Hecht, these tubes are suited to research, quality-control and educational laboratories that require consistent, reusable glass consumables. The clear glass wall permits direct visual inspection of colour changes, precipitates and phase separations. Dimensions of approx. 130 × 14 mm make them practical for medium-volume samples, qualitative tests and teaching demonstrations. These heavy-wall borosilicate test tubes integrate smoothly into everyday laboratory workflows needing durable glassware with a plain rim.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, borosilicate glass 3.3, heavy wall rimless mm Ø ca. 130 x14
What is this article?
Test tubes, borosilicate glass 3.3, heavy wall rimless mm Ø ca. 130 x14 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.
