Description
Rotilabo® test tubes with beaded rim are thick-walled laboratory tubes made from borosilicate glass 3.3 and offer a nominal volume of 32 ml for everyday sample handling. The beaded rim supports secure gripping and reliable seating of stoppers or closures during routine preparation, mixing, and transfer steps. Borosilicate glass 3.3 is a standard laboratory material chosen for its favourable thermal and chemical resistance profile, while the thick-walled build adds mechanical robustness for frequent use on the bench. These tubes suit general analytical, quality-control, and teaching workflows where clear visual inspection of contents and consistent geometry for rack storage are important. Packaged as 100 pc(s) with a total weight of 2,930 kg, the set provides a practical bulk format for busy laboratories. The Rotilabo® line from manufacturer ROTH SELECTION delivers a straightforward glass consumable for organised sample work without unnecessary complexity. Whether used for temporary holding, simple reactions within the limits of borosilicate glass 3.3, or transfer between workstations, the 32 ml beaded-rim design remains a dependable choice for standard labware inventories.

Questions about Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 32ml
What is this article?
Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 32ml 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.
