Description
Test tubes of borosilicate glass 3.3 in heavy-wall design with beaded rim provide robust vessels for sample handling, heating and general laboratory work. Measuring approximately 200 mm in length and 38 mm in diameter, these tubes combine mechanical strength with the well-known chemical and thermal resistance of borosilicate glass 3.3. The reinforced wall thickness supports repeated use under thermal stress, while the beaded rim improves handling safety and facilitates secure stoppering or covering. Suitable for qualitative and quantitative procedures, reaction monitoring and storage of aqueous or organic media within the limits of the glass type, they fit standard racks and heating blocks. Supplied in packs of 100 pieces from manufacturer Hecht, the tubes are intended for routine analytical, educational and research environments where reliable glassware of defined dimensions is required. Clear dimensional data and material specification allow straightforward matching to existing protocols and equipment.
This article is part of Test tubes, in Tubes & vials.

What is this article?
Test tubes, borosilicate glass 3.3, heavy wall with rim mm Ø ca. 200 x38 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.
