Description
Rotilabo® test tubes with straight rim are thick-walled laboratory tubes made from borosilicate glass 3.3 and offered with a nominal capacity of 70 ml. The straight rim geometry supports easy filling, pouring, and access with pipettes or simple closures during routine sample work. Borosilicate glass 3.3 is widely used in laboratory glassware for its chemical resistance and suitability for thermal stress in everyday heating and cooling steps. The thick-walled build adds mechanical robustness for repeated handling on the bench. These tubes are intended for general laboratory use with samples, reagents, and intermediate preparations where clear glass vessels are required. Pack size is 50 pc(s), giving a practical stock quantity for teaching, quality control, and research workflows that process multiple tubes in parallel. The pack weight is 2,000 kg. Rotilabo® test tubes from manufacturer ROTH SELECTION fit standard racks and common wet-chemistry procedures involving aqueous media and many solvents compatible with borosilicate glass 3.3. Transparent walls allow direct visual checks of colour, turbidity, and phase behaviour without transferring the contents. The combination of straight rim, thick wall, and 70 ml capacity makes this variant a straightforward choice for preparatory chemistry, observation, and short-term holding of laboratory samples.

Questions about Rotilabo®-test tubes, straight rim, borosilic. glass 3.3, thick walled, 70ml
What is this article?
Rotilabo®-test tubes, straight rim, borosilic. glass 3.3, thick walled, 70ml 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.
Which category should I open next?
