Description
Heavy-wall test tubes with plain rim, soda-lime glass, approx. 40 x 8 mm are sturdy laboratory tubes designed for reliable sample and reagent handling. With a length of 40 mm and a diameter of 8 mm, they are produced from soda-lime glass (Kalk-Natron-Glas) that combines optical clarity with solid mechanical strength. The heavy-wall design improves resistance to everyday laboratory stresses, while the plain smooth rim simplifies filling, emptying and cleaning. Packaged in units of 100 pieces and carrying a gross weight of 0,164 kg, these tubes are well suited to general analytical, quality-control and educational applications. Manufacturer Hecht supplies this format for use as reaction tubes, sample tubes or reagent vessels where consistent dimensions and durable glassware are needed. The approximate sizing reflects standard manufacturing tolerances for soda-lime glass test tubes of this type, ensuring practical compatibility with common laboratory racks and holders.

Questions about Test tubes, heavy wall, rimless, soda lime glass mm Ø ca. 40x 8 Nr. 42775009
What is this article?
Test tubes, heavy wall, rimless, soda lime glass mm Ø ca. 40x 8 Nr. 42775009 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.
