Spectra/Por® Dynamic Dialysis Tank System

Easy Process Scale Dialysis

Dialysis Recirculation Tank

The Spectra/Por® Dynamic Dialysis Tank System makes dialysis of larger sample volumes ranging from 100 ml to 2 liters faster and more efficient. The system allows for a continuous buffer flow (50-200ml/min) from a remote dialysis feed reservoir (up to 1000 L). Continuous flow maintains a higher concentration gradient and faster rate of dialysis compared to traditional static dialysis with manual buffer changes. The tall, cylindrical tank enables the efficient removal of solutes by keeping the buffer close to the membrane surface.

Benefits of Dynamic Dialysis

  • Shorter run time
  • Higher sample purity
  • No manual buffer changes
  • Smaller footprint
  • Smaller buffer volume required
