Biopharmaceutical Chromatography Systems are designed for separating and purifying proteins and bio-engineered products. Flow systems are compact in design to maximize throughput. No dead legs in process pipe can exist since unswept areas are more challenging to completely clean as well as delaying product throughput. The systems must maintain a hygienic design. Wetted surface finish must be < 20 μinch Ra and material traceability is important to maintain system integrity.
