Description
Graduated fermentation tubes complete with test tube are specialised glassware assemblies designed for Merck water examination procedures. Each complete unit comprises a graduated fermentation tube paired with a matching test tube, enabling clear observation and measurement of gas formation during microbial fermentation assays. Intended for laboratory culture-tube applications, these sets support standardised water-quality testing by facilitating reliable detection of fermenting organisms. Offered by manufacturer Witeg, the product provides a ready-to-use configuration that simplifies preparation for microbiological water analysis. The graduated scale on the fermentation tube allows precise reading of gas volumes produced, which is essential for interpreting results according to established Merck protocols. Suitable for environmental testing laboratories, public-health facilities and quality-assurance departments, these complete fermentation tubes with test tubes deliver consistent performance in coliform and related fermentation studies. Supplied as individual pieces, they integrate easily into routine screening and specialised research workflows involving water samples.
This article is part of Test tubes, in Tubes & vials.

Questions about Fermentation tubes, grad., complete wit
What is this article?
Fermentation tubes, grad., complete wit is the article on this page. Luminix Health distributes Witeg 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.
