Description
Test tubes 150 x 25 mm are ungraduated laboratory vessels produced from borosilicate glass 5.1. They incorporate a straight rim, round bottom, wall thickness of 1,0 mm and a nominal volume of 55 ml, with dimensions of 150 mm length by 25 mm diameter. These larger-capacity tubes are practical for sample storage, medium-scale reactions, mixing and general laboratory handling in research, quality-control and teaching environments. The round bottom promotes efficient mixing and cleaning, while the straight rim facilitates stoppering or covering as needed. The thicker wall and robust borosilicate construction offer dependable chemical resistance and thermal stability for routine laboratory operations. Packed in cartons of 100 pieces from manufacturer Marienfeld, they form a convenient unit for laboratories requiring moderate volumes. Their plain ungraduated design ensures flexibility for qualitative tests and preparatory work where marked volume scales are unnecessary, helping maintain efficient sample-processing routines across a variety of experimental applications.

Questions about Test tubes 150x25 mm,
What is this article?
Test tubes 150x25 mm, 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.
