Description
Cork rings for round-bottom flasks with 2000–4000 ml give stable bench support for larger spherical reaction vessels. Specified for flasks from 2000 to 4000 ml, each ring has an upper diameter of 140 mm, a base diameter of 90 mm and a height of 30 mm, aligning with the broader curvature of high-capacity round-bottom glassware. Cork provides a resilient contact surface that helps protect the flask wall and reduces the tendency of free-standing vessels to roll or tip during preparation, cooling or temporary placement. Supplied as 1 pc with a net weight of 0,06 kg, the ring is practical for stocking beside large-scale set-ups. These supports from manufacturer Witeg fit synthesis, concentration and distillation work where 2–4 litre flasks are handled regularly between mantles, stands and the laboratory bench. Dimensioning for the 2000–4000 ml class improves seating stability compared with undersized rings and supports orderly, safer glassware handling in research and teaching environments that need straightforward reusable flask bases.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Cork ring for round-bottom flasks with 2000-4000ml
What is this article?
Cork ring for round-bottom flasks with 2000-4000ml is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
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.
