If the free cross-sections obtained with the combination of column sections and packing supports are not large enough, then an alternative is to use type APS pipe sections in combination with fixed support plates. Each item comprises the glass supports plate, screwed rod with nuts, flat washers and compression springs and the special backing flange required for the assembly. Notes of use of column packing:1. Due to their low bulk densities, glass rasching rings are particularly suitable for packing glass columns.2. Generally theratio of column diameter to packing diameter sholuld not beless than 8:1.3. When using smaller packing size, a small layer of larger packing sholud 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 other parts. To prevent this, a packing retainer (PTFE Performance Plates) should be used above the packed section.
