Description
Test tube brushes featuring a bristle section of 90 × 25 mm (length × diameter) and a total length of 280 mm deliver effective cleaning for larger-diameter laboratory tubes. The bristle packing is finished with a wool tuft that reaches tube bottoms gently while the denser bristles scrub the inner walls. A galvanised wire handle with an end loop supports hanging storage and keeps the brush ready for the next wash cycle. Packed in units of 10 pieces and offered by manufacturer Marienfeld, these brushes are suited to routine glassware care in research, teaching and industrial laboratories. The wider 25 mm bristle diameter addresses broader test tubes and similar cylindrical vessels, while the 280 mm overall length maintains good handling reach. Durable wire construction retains form under repeated wet use. A dependable choice for wash-up stations, sample preparation benches and general laboratory cleaning workflows that demand sturdy, hangable tube brushes.

Questions about Test tube brushes,
What is this article?
Test tube brushes, is the article on this page. Luminix Health distributes Marienfeld 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.
