TOYOPEARL IEXPAK HP contains multi-milliliter containers of four TOYOPEARL ion exchange chromatography bulk media products: TOYOPEARL DEAE-650S, TOYOPEARL SP-650S, TOYOPEARL CM-650S and TOYOPEARL SuperQ-650S.

These multi-packs are useful for developmental engineers who wish to familiarize themselves with resin physical properties in different buffer systems:

• Slurry and re-slurry mechanics
• Resin handling during column packing
• Mechanical strength relative to agarose
• Degree of compressibility
• Flow adaptor regimen

The larger resin amounts in LabPak products allow the packing of wider ID and longer columns than available in the ToyoScreen products. This helps the developmental chemist or engineer to better measure under actual packing conditions the following properties:

• Dynamic binding capacity
• Selectivity
• Column efficiency
