Expanding The Viscosity Limits Of Peristaltic Dosing

By Harry Price, 3P innovation

Modern injectable formulations, particularly in cell and gene therapy, are trending toward higher concentrations and viscosities that often exceed the operational limits of traditional peristaltic systems. Once fluids surpass 100 cP, elastic recovery in tubing degrades, leading to significant flow inconsistencies. While piston pumps offer a mechanical alternative, they sacrifice the single-use benefits critical for aseptic processing and introduce complex cleaning validation.

New performance data reveals that integrating closed-loop feedback and precision servo control allows peristaltic technology to maintain volumetric accuracy with fluids up to 2000 cP. Comparative studies demonstrate that this approach not only drastically improves accuracy against industry-standard units but also sustains performance over thousands of doses. Read the full analysis to see how peristaltic dosing is expanding into high-viscosity applications.
