Spectra/Por^® Dialysis Recirculation Tank

The Spectra/Por® Dialysis Recirculation Tank makes dialysis of larger sample volumes ranging from 100 ml to 2 liters faster and more efficient. Since the 5 liter, 7 liter, and 10 liter Dialysis Recirculation Tank are equipped with flow-through inlet/outlet ports, the buffer source can be located remotely in a much larger reservoir (20 - 1000 liters) and continuously pumped via flexible tubing at a rate of 100-200 ml/min around the outside of the dialysis membrane tubing. This large volume dynamic dialysis with either buffer recirculation or single-pass (direct to drain) maintains a higher concentration gradient and rate of dialysis as compared to static buffer changes (4 - 10 volume changes). This increased efficiency often reduces the total buffer volume required for sample purification and saves time.
