TOYOPEARL AFFIPAK contains multi-milliliter containers of three TOYOPEARL affinity bulk media products: TOYOPEARL AF-Amino 650M, TOYOPEARL AF-Carboxyl-650M, and TOYOPEARL AF-Formyl-650M.

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
