Description
Test tubes 100 x 16 mm with round bottom are plain laboratory sample tubes manufactured from soda-lime glass for routine chemical, teaching and quality-control work. Each tube is 100 mm long and 16 mm in diameter, with a wall thickness of 0,9 mm and a smooth rim that supports easy handling, stoppering and transfer. The round-bottom geometry suits mixing, gentle heating and general sample preparation where visual clarity of the contents is important. Packs contain 100 pieces, giving a convenient stock format for high-throughput benches and shared laboratory stores. These tubes from manufacturer Hirschmann fit standard racks and holders designed for 16 mm outer diameter glassware and are well suited to qualitative tests, reagent aliquots and educational demonstrations. Soda-lime glass offers good optical transparency at a practical cost for applications that do not demand borosilicate thermal-shock performance. Net pack weight is 1,100 kg. Use them wherever consistent dimensions and a simple round-bottom profile are required for everyday laboratory procedures.

Questions about TEST TUBES, 100 X 16 MM, ROUND BOTTOM (1 PACK=100 PCS)
What is this article?
TEST TUBES, 100 X 16 MM, ROUND BOTTOM (1 PACK=100 PCS) is the article on this page. Luminix Health distributes Hirschmann 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.
