Questions about Vial N18-20, SC, c, 22.5x75.5, rounded
What is this article?
Vial N18-20, SC, c, 22.5x75.5, rounded is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Sample vials & NMR tubes, inside Tubes & vials, in Labware.
A sample vial is a small closed bottle for keeping or for presenting a sample. An NMR tube is a precision glass tube: the wall has to be straight and the diameter has to match the probe, or the spectrum contains the tube.
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.
