DEVICE AND METHODS FOR IMPROVING AND EVALUATING STABILITY OF PUMPED PROTEIN SOLUTIONS IN BIOPROCESSING SYSTEMS

摘要

The present invention relates to devices and methods for improving and evaluating stability of pumped protein solutions in cross-flow filtration applications. Inter alia, the present invention provides a peristaltic pump for cross-flow filtration having a pump head (1), wherein the pump head (1) comprises a stepped occlusion plate (2) and at least one pump roller (3), wherein a tubing is to be arranged between the stepped occlusion plate (2) and the at least one pump roller (3), wherein the stepped occlusion plate (2) has a specific configuration.
