Diafiltration exchange factor
WebDiafiltration and dialysis can both be used for buffer exchange, but application and sample type determine when each is best used. To learn more about the di... WebBatch diafiltration, also called discontinuous diafiltration,2 is sometimes used at small-scale operation to ‘wash out’ permeable contaminants from a solution or exchange buffers. First, a fluid undergoes a concentration step where the solvent and permeable components pass through the membrane while retained components are concentrated.

Several UF/DF operations can be connected in a series to perform multiple UF/DF steps until the desired purity levels are reached.
WebDiafiltration. Diafiltration is a process for separation and purification of the target product out of the main solution containing the other small molecular weight (MW) substances, e.g. salts, solvent. The term ‘diafiltration’ means a combination of ‘dilution’ and ‘filtration’. A buffer solution or demineralized water is added into ...
