Description
Rotilabo® test tubes with beaded rim are thick-walled laboratory tubes made from borosilicate glass 3.3 for routine sample handling, heating steps and general wet-chemistry work. The 70 ml format suits aliquots, intermediate dilutions and short-term storage of aqueous or organic media where mechanical robustness and thermal stability matter. Borosilicate glass 3.3 offers low thermal expansion and good chemical resistance against many laboratory reagents, supporting repeated use under controlled conditions. The beaded rim strengthens the mouth of the tube, improves handling with tongs or fingers and helps seating of stoppers or covers when temporary closure is required. Thick walls add durability during transport within the lab and during moderate thermal cycling. Supplied in packs of 50 pieces from manufacturer ROTH SELECTION, these tubes fit standard racks and common laboratory workflows in research, quality control and teaching environments. Clear glass walls allow visual inspection of contents, phase separation and colour changes without transfer. Use them for sample preparation, reaction monitoring and temporary holding of process intermediates wherever a sturdy, reusable glass tube of defined capacity is preferred over thin-walled disposables.
This article belongs on Test tubes, in Tubes & vials.

Questions about Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 70ml
What is this article?
Rotilabo®-test tubes, beaded 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.
