Blood plasma manufacturing

The Polaris Refractometer is an accurate, in-line, and real-time measurement instrument, that enables:


  • Control of retentate concentration for optimal permeability 
  • Accurate and real-time measurements of protein concentration 
  • Optimal end-product concentration and quality
  • Improved process throughput time by bypassing the sample-based Kjeldahl or Dumas methods

This application note explains how a refractometer can improve process with recommended installation points for best performance.
