Beschrijving
Durham tubes 12 x 50 x 0,8 mm are small inverted glass tubes used for the detection of gas formation by microorganisms. Measuring 12 × 50 × 0,8 mm, they are placed inside culture tubes so that any gas produced during microbial metabolism collects as a visible bubble, providing a clear qualitative indication of gas generation. Manufactured from highly durable soda glass, these tubes offer good mechanical and chemical resistance for repeated microbiological use. They are supplied in a practical pack of 100 pieces from manufacturer Dinkelberg, supporting efficient stocking for teaching laboratories, quality-control microbiology and routine fermentation or biochemical tests. The soda-glass construction helps maintain clarity and robustness under typical autoclaving and culture conditions associated with gas-detection assays. With defined outer dimensions of 12 mm by 50 mm and a wall thickness of 0,8 mm, the tubes fit standard culture vessels used in gas-production tests. This pack format suits laboratories that require a reliable supply of Durham tubes for consistent observation of microbial gas formation.

Questions about Durham tubes 12x50x0.8mm, 100 pcs/pkg
What is this article?
Durham tubes 12x50x0.8mm, 100 pcs/pkg is the article on this page. Luminix Health distributes Dinkelberg for laboratory use. It sits in Reageerbuizen, inside Buizen & flacons, in Labmateriaal.
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.
