Raschig rings are named after their inventor, the German chemist Friedrich Raschig.ceramic raschig rings are pieces of tube, approximately equal in length and diameter. Ceramic raschig rings used as a column packing, used in large numbers as a packed bed within columns for distillations and other chemical engineering processes. They are usually ceramic or metal and provide a largesurface area within the volume of the column for interaction between liquid and gas or vapour.
0.25" 6mm ceramic raschig ring, 3mm ceramic raschig rings column packing will increase the proof output of a column still. These durable rings will last a lifetime and only needs to be rinsed after use. Lianchuang's ceramic raschig ring is shaped by mould instead of cut by human reasouce, our ceramic raschig rings have high precision, we could also produce the ceramic raschig with high alumina ceramic material.
