Diafiltration - an overview ScienceDirect Topics

WebDiafiltration can be performed in either continuous or discontinuous mode. Discontinuous diafiltration refers to a practice where the sample is first concentrated, then diluted with exchange buffer to the initial starting volume, followed by another concentration step. This process is repeated until the desired microsolute has been exchanged. Diafiltration is a dilution process that involves removal or separation of components (permeable molecules like salts, small proteins, solvents etc.,) of a solution based on their molecular size by using micro-molecule permeable filters in order to obtain pure solution. 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... cinnabon clackamas town center
