Description
Rotilabo® test tubes with beaded rim are thick-walled tubes produced from borosilicate glass 3.3 and sized for a nominal volume of 40 ml. The beaded rim improves handling safety and helps seat stoppers or closures securely during sample preparation, mixing, and transfer. Thick-walled construction adds mechanical strength for repeated bench use, while borosilicate glass 3.3 contributes the thermal and chemical resistance expected of standard laboratory glassware. Clear walls allow straightforward visual inspection of samples, and the uniform shape supports orderly rack storage in research, quality-control, and educational laboratories. Supplied in packs of 100 pc(s) with a total weight of 3,480 kg, these tubes give laboratories a ready bulk stock of durable glass consumables. The Rotilabo® range from manufacturer ROTH SELECTION addresses everyday needs for reliable test tubes without elaborate accessories. With a 40 ml working volume, the design fits common workflows that require slightly larger capacity than smaller culture or reaction tubes while remaining easy to handle and store.
This article is part of Test tubes, in Tubes & vials.

Questions about Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 40ml
What is this article?
Rotilabo®-test tubes, beaded rim, borosilic. glass 3.3, thick walled, 40ml 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.
