Webthe maximum flow rate, see Table 1, on page 4 and Table 2, on page 5, is typically employed during packing. Note: If you have packed at the maximum linear flow rate, do not exceed 75% of this in subsequent chromatographic procedure. 7 Open the bottom outlet of the column and set the pump to run at the desired flow rate. This should be at WebThe benefits of membrane chromatography include: High binding efficiency due to direct access to the binding groups, even at high flow rates. Speed – high flow rates enable the processing of large volumes. As an example, Pall Mustang® capsules typically operate at a flow rate of 10 membrane volumes (MV) per minute, which equates to 50 L per ... ironite scotts spreader setting

WebIf the recommended flow rate cannot be obtained, use the maximum flow rate the pump can deliver. Maintain the packing flow rate for at least 3 CV after a constant bed height is obtained. Mark the bed height on the column. Do not exceed 70% of the packing flow rate during any purification. Stop the pump and close the column outlet.
