Product Description

Raschig rings are named after the inventor, the German chemist Friedrich Raschig, ceramic raschig ring‘s a very simple ring shape with approximately equal in length and outside diameter. Ceramic raschig ring can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and ceramic raschig ring can be used in high or low temperature conditions. Raschig rings’ surface ratio is higher than ceramic cylinders and balls by 30% and its ring shape has high mechanical stability. Ceramic raschig ring often used in large numbers as a packed bed within columns for distillations and other chemical engineering processes. They can provide a large surface area within the volume of the column for interaction between liquid and gas or vapour. And the form enabled Raschig to perform distillations of much greater efficiency than his competitors using fractional distillation columns with trays.( not ceramic saddles )  We has all kinds of size and material rasching ring, welcome contact and advise us which model you need.
