Description
Rotilabo® test tubes with beaded rim are thick-walled laboratory tubes produced from borosilicate glass 3.3 with a nominal capacity of 5 ml. The beaded rim reinforces the tube opening and supports confident handling, simple covering, and stable seating in standard racks. Borosilicate glass 3.3 is commonly specified for laboratory vessels because of its chemical resistance and behaviour under typical bench heating and cooling. Thick-walled construction improves mechanical robustness during repeated use, transport between stations, and mixing. The 5 ml volume suits small-scale sample work, qualitative tests, and limited reagent portions. Units are packed as 100 pc(s), a convenient quantity for shared laboratories and series experiments. Pack weight is 0,680 kg. These Rotilabo® tubes from manufacturer ROTH SELECTION belong to everyday laboratory glassware for applications compatible with borosilicate glass 3.3. Clear glass enables direct observation of colour development, turbidity, and separations without sample transfer. Combining a beaded rim, thick wall, and 5 ml capacity, this variant offers a compact, durable tube for teaching, quality control, and research tasks that rely on small transparent glass vessels.
This article is part of Test tubes, in Tubes & vials.

Questions about Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 5 ml
What is this article?
Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 5 ml is the article on this page. Luminix Health distributes Carl Roth 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.
