Process Intensification

MORE. FASTER.

Bioprocess intensification is defined as a significant step increase in output relative to cell concentration, time, reactor volume or cost, resulting in improvements in productivity, environmental and economic metrics.

Bioprocess intensification usually involves a drastic change in equipment and/or process design e.g., moving from batch to continuous processing or integrating new process steps. The result is not only a considerable increase in productivity but a significant improvement in other environmental and economic metrics such as energy consumption, carbon footprint, OPEX and CAPEX. 

Benefits of process intensification in bioprocessing

Perfusion Cell Culture

Perfusion, a cornerstone of upstream continuous bioprocessing, has been practiced since the 1980s to maximize facility utilization, expand process flexibility and minimize costs. Today, novel cell retention devices and single-use technologies, with sophisticated control logic, simplify implementation.

N-1 Perfusion

A form of seed train intensification, N-1 perfusion refers to the intensification of cell growth in the seed train step (N-1) before the production bioreactor (N), achieving a more rapid and robust process while maintaining an existing Fed-Batch based production scheme.

Seed Train Intensification

Seed train intensification aims to generate ultra high-density cell cultures at optimal points during cell expansion using a robust cell retention device prior to the inoculation of the production bioreactor.

High Productivity Harvest

High Productivity Harvest (HPH) is a novel application developed by Repligen that enables the harvest of a Fed-Batch bioreactor in a fully sterile manner ready for processing on a capture column, eliminating both centrifugation and depth filtration.
