An open ring retort support is a laboratory apparatus used to hold glassware such as flasks, beakers, or test tubes during experiments. It consists of an open circular ring made of Ni/Cr plated steel with a retort support at the bottom. The open design of the ring allows for easy placement and removal of glassware. The Ni/Cr plating provides the retort support with corrosion resistance and durability. The retort support can be adjusted to accommodate different sizes of glassware. The open ring retort support is suitable for various laboratory applications, including distillation, filtration, and heating of solutions.
