Description
Rotilabo® test tubes with beaded rim are thick-walled laboratory tubes made from borosilicate glass 3.3 and sized for a nominal capacity of 4 ml. The beaded rim strengthens the mouth of the tube and aids secure handling, covering, and placement in racks during small-volume work. Borosilicate glass 3.3 is established laboratory glassware material chosen for chemical resistance and suitability under ordinary thermal load in wet chemistry. Thick-walled design contributes to durability when tubes are repeatedly gripped, mixed, or transferred. This compact 4 ml format is appropriate for micro-scale samples, spot tests, and reagent aliquots where minimal volume is preferred. Pack size is 100 pc(s), supporting high-throughput or multi-user laboratory settings. Pack weight is 0,480 kg. Rotilabo® test tubes from manufacturer ROTH SELECTION are intended for routine laboratory glassware use with media compatible with borosilicate glass 3.3. Transparent walls allow immediate visual assessment of colour, clarity, and phase behaviour. The beaded rim, thick wall, and 4 ml capacity together provide a practical small-volume option for teaching benches, analytical screening, and preparatory steps that do not require larger vessels.
This article is part of Test tubes, in Tubes & vials.

Questions about Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 4 ml
What is this article?
Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 4 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.
