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 support, to
  prevent the smaller packing falling through.
- In vacuum application and applications involving high vapor 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.
