1. Due to their low bulk densities, Glass Raschig rings are particularly suitable for packing Column Componentss.
2. Generally, the ratio of Column diameter to packing diameter should not be less than 8:1
3. When using smaller packing size, a small layer of larger packing should be used on packing support, to prevent the smaller packing falling through.
4. In vacuum application and applications involving high vapour velocities, packing may be lifted and may damage to other parts. To prevent this, a packing retainer (PTFE perforated plates) should be used above the packed section.
Pall Rings are also available for column packing as per specification.
