LabPak products are multi-milliliter containers of Toyopearl and TSK-GEL bulk media products. Typically they contain 3 or 4 different ligand types offered for a particular chromatography mode.

They are useful for developmental engineers who wish to familiarize themselves with resin physical properties in different buffer systems:

• slurry and reslurry 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 I.D. and longer columns than available in the ToyoScreen products. This helps the developmental chemist or engineer to better measure under actual packing conditions the resin's:

• dynamic binding capacity
• selectivity
• column efficiency
