SpectraFlo™ Dynamic Dialysis Systems

SpectraFlo™ Dynamic Dialysis Systems are the only commercially available systems for scalable dynamic dialysis from lab scale to large volume processing. 

Dialysis Tubing Closures

Tubing Closures are the preferred method for sealing dialysis tubing to minimize the risk of sample leakage. While tied knots often leak, damage the membrane and are difficult to open, Tubing Closures are easy to apply, ensure a leak-proof seal and are re-usable.
