Single-Use Crossflow

Speed Up with Single-Use Crossflow Solutions

Reduce Time-to-Market

Single-use crossflow solutions are the key technology in fast and reliable downstream processing of biopharmaceutical products. Using a pre-sanitized, sterile single-use crossflow device enables the reduction of process steps, labor costs and buffer or WFI usage significantly. Our crossflow single-use systems set a benchmark in process safety and user friendliness. Smart process transfers are supported by our DCU-4 platform technology and analysis tools.
