Description
neoChoice Durham tubes, 46 x 15 mm OD, are soda-lime glass culture tubes with a round bottom and straight rim for microbiological gas-detection work. Placed inverted inside larger culture tubes or fermentation media, they collect gas evolved by microorganisms and make bubble formation easy to observe during growth assays. The transparent glass body supports clear visual readout of gas production in classic Durham-tube tests used in teaching, quality control, and routine microbiology laboratories. Measuring 46 x 15 mm outer diameter, the tubes fit standard setups for fermentation and biochemical identification workflows. Supplied by manufacturer neolab - Labor in packs of 100 pieces, they offer a practical consumable format for high-throughput or classroom use. These neoChoice Durham tubes are intended wherever simple, reliable glass inserts are needed to indicate microbial gas formation without complex instrumentation, supporting consistent observation of metabolic activity in liquid cultures.
This article is part of Test tubes, in Tubes & vials.

Questions about neoChoice Durham-Röhrchen, 46x15 mm AD; Pack a 100 Stück
What is this article?
neoChoice Durham-Röhrchen, 46x15 mm AD; Pack a 100 Stück is the article on this page. Luminix Health distributes neolab 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.
