Column Packing - Raschig Rings

Raschig rings up to 25mm are of neutral glass. 40mm and 50mm raschig rings are available only in Borosilicate glass.

Notes of use of Column Packing - Due to their low bulk densities, glass raschig rings are particularly suitable for packing glass columns. - Generally, the ratio of column diameter to packing diameter should not be less than 8:1 - When using smaller packing size, a small layer of larger packing should be used on packing falling through. - In vacuum application and applications involving high vapour velocities, packing may be lifted and may damage other parts. To prevent this, a packing retainer (PTFE perforated plates) should be used above the packed section.
