![]() Example for Fine Removal: 5 liter resin ordered = 7 8 liter of suspension in total (65 70 % slurry concentration) Fill in a 20 liter vessel and fill up with 12 liter water. ![]() ![]() Add distilled water or buffer to 4 times the resin volume and stir thoroughly. Once suspended, transfer the required amount of suspension (approximately 4 volumes suspension = 3 volumes resin) into a container of sufficient volume to hold 4 times the volume of resin being prepared. a) The settled resin in the shipping containers should be suspended by vigorous agitation or stirring with a rod or paddle (do not use a magnetic stirrer it will grind the resin, generating fines). The following decantation process is required to remove fines from the resin slurry. Fines in the gel slurry may obstruct screens or sintered filters and may eventually increase the pressure drop across the column. FIGURE 1 Equipment required for packing 1.2 Removal of Fines Tosoh Bioscience recommends that fines be removed. 1) required to successfully pack resins are: a pump, a pressure gauge, a level, glasses, acrylic or PEEK or stainless steel column and a packing reservoir (optional). Although it is not recommended, resins can be packed by simple gravitational settling. Preparation for Packing 1.1 General Considerations for Packing It is best to pack resins by the application of pressure from 0.05 to 0.3 MPa across the bed length. It also confers upon the resin excellent pressure/flow characteristics and ph stability. These resins are a modified methacrylate polymer which gives the resin a hydrophilic surface due to the presence of ether and hydroxyl groups. They are applicable for the laboratory and process scale purifications of globular proteins, peptides, nucleic acids, and other biologically derived materials.
