Ballasting Rings, Laboratory Glassware
Definition : Rings designed to fit around laboratory glassware (e.g., flasks) for stabilization when the glassware is immersed in water. These devices usually consist of rings made of lead and covered with vinyl or PVC to avoid scratching the glass. Ballasting rings can be open or closed loop devices; they are available in different sizes and weights according to the glassware diameter and the intended use (e.g., water bath).
