Description
DURAN® test tubes with blue graduation 10:0,1 ml are precision laboratory glassware featuring an NS 12/21 ground joint and a length of 170 mm. Manufactured from borosilicate glass 3.3, these tubes offer the chemical resistance and thermal stability expected in analytical and preparative work. Each tube has an outer diameter of 14 mm and a nominal volume of 0,01 l, with clear blue graduation marks for convenient volume reading at 0,1 ml intervals up to 10 ml. Supplied complete with NS ground joint and poly stopper, they support secure temporary closure during sample handling and short-term holding of reagents or intermediates. Available in packs of 10 pieces from manufacturer Hirschmann, the tubes suit routine chemistry, biology, and quality-control applications where graduated DURAN® glassware is preferred. The combination of standardized joint dimensions, durable borosilicate construction, and legible blue scale markings makes them a practical choice for repeated laboratory use alongside complementary ground-joint apparatus and stoppers.
This article is part of Test tubes, in Tubes & vials.

Questions about TEST TUBES, DURAN®, BLUE GRAD, 10:0,1 ML, NS 12/21, L 170 MM
What is this article?
TEST TUBES, DURAN®, BLUE GRAD, 10:0,1 ML, NS 12/21, L 170 MM 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.
