Description
DURAN® test tubes measuring 15 x 150 mm are graduated laboratory tubes manufactured from DURAN tubing and fitted with a practical pouring spout. Constructed from borosilicate glass 3.3, they combine high chemical resistance with low thermal expansion, making them well suited to routine heating, cooling and reaction work. The clear graduation scale covers 10 ml in 0,1 ml divisions, supporting convenient volume estimation during sample preparation, qualitative analysis and general wet-chemistry procedures. Each tube is supplied as a single piece with a net weight of 0,018 kg and offers excellent optical clarity for observing colour changes, precipitates or phase separations. Produced by manufacturer Witeg, these robust tubes deliver consistent dimensions and reliable everyday performance in research, quality-control and teaching laboratories. The spout design aids controlled pouring and reduces dripping when transferring liquids, while the durable wall construction supports repeated use after proper cleaning. Ideal for chemistry, biology and educational applications that require reusable borosilicate glassware with dependable thermal and chemical stability.

Questions about Test tubes, made from DURAN tubing, gr
What is this article?
Test tubes, made from DURAN tubing, gr is the article on this page. Luminix Health distributes Witeg 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.
