Description
Test tubes of borosilicate glass 5.1 with beaded rim, approximately 160 mm in length and 16 mm in diameter, are classic laboratory vessels for holding, mixing and observing liquid samples and reagents. The cylindrical form with a reinforced beaded rim supports secure handling and helps the open end seat stoppers or covers during routine bench work. Clear glass walls allow direct visual inspection of colour changes, precipitates and phase behaviour in qualitative tests and small-scale preparations. Supplied in packs of 100 pieces from manufacturer Hecht, the format suits teaching laboratories, quality-control benches and research groups that use tubes in high daily numbers. The approx. 160 × 16 mm size fits standard racks and holders and offers a familiar working volume for sample aliquots, reagent checks and short-term storage. Borosilicate glass 5.1 construction is intended for general chemical and biological laboratory practice where thermal and chemical robustness of everyday glassware is expected. These reaction and sample tubes integrate smoothly into established workflows for sample preparation, observation and transfer without specialised accessories.

Questions about Test tubes of borosilicate glass 5.1, with rim mm Ø ca. 160 x 16
What is this article?
Test tubes of borosilicate glass 5.1, with rim mm Ø ca. 160 x 16 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.
