Description
Rotilabo® cork rings are laboratory supports made from compressed cork and sized for round flasks of 20 000 ml. They provide a stable, non-slip base that helps keep large glass vessels upright on the bench during filling, heating setup, cooling, or temporary storage. The resilient cork surface cushions the flask wall and reduces the risk of scratching or rolling, which is especially useful when working with bulky round-bottom flasks in preparative and pilot-scale work. Each pack contains 2 pc(s) and has a total weight of 0,200 kg, making the set easy to place wherever flask support is needed. These rings belong to the Rotilabo® labware line from manufacturer ROTH SELECTION and fit naturally among stands and cork-ring accessories used with laboratory glass, vessels, and consumables. Compressed cork offers a practical balance of grip, light weight, and chemical inertness for routine wet-chemistry environments. Use them as dedicated flask rests beside rotary evaporators, reaction setups, or storage areas so large 20 000 ml flasks remain secure between handling steps without improvised supports.
This article is part of Flasks (other), in Beakers & flasks.

Questions about Rotilabo®-cork rings, compressed cork, f. flasks 20 000 ml, 2 unit(s)
What is this article?
Rotilabo®-cork rings, compressed cork, f. flasks 20 000 ml, 2 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Flasks (other), inside Beakers & flasks, in Labware.
These are the flasks that are not a plain beaker, Erlenmeyer, round bottom or flat bottom: odd shapes, special necks, flasks defined by a use. The volume and the joint, if there is one, still have to match the setup.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
