Description
Rotilabo® test tubes with beaded rim are thick-walled laboratory tubes manufactured from borosilicate glass 3.3 for sample preparation, heating and general analytical work. The 100 ml capacity supports larger aliquots, dilutions and short-term holding of aqueous or organic solutions when mechanical strength and thermal performance are important. Borosilicate glass 3.3 combines low thermal expansion with broad chemical resistance, making the tubes suitable for repeated laboratory cycles under controlled conditions. A beaded rim reinforces the tube mouth, eases handling and assists seating of stoppers or temporary covers. Thick-walled construction increases durability during rack transport, moderate thermal stress and everyday bench use. Packs of 50 pieces from manufacturer ROTH SELECTION integrate readily into standard racks and workflows in research, quality control and teaching laboratories. Transparent walls enable direct observation of fill level, phase boundaries and colour development without transferring the sample. Choose this format when a robust, reusable glass tube of defined 100 ml volume is preferred for intermediate processing steps, reaction monitoring or temporary storage of process materials.
This article belongs on Test tubes, in Tubes & vials.

Questions about Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled,100ml
What is this article?
Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled,100ml is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Test tubes, inside Tubes & vials, in Matériel de laboratoire.
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.
