Spectra/Por® Hollow Fiber Dialysis Modules
Highly Efficient Dialysis of Multi-liter Volumes!

Only Spectrum offers a highly efficient, counter-current dialysis device convenient and easy enough to operate in the laboratory. Based on the mechanics of a kidney, the Spectra/Por HF Dialysis Module is designed to provide much better performance than a conventional dialysis membrane used in a typical "static" dialysis set-up. The dialysis module consists of an open-ended bundle of hollow fiber membrane potted in a tubular housing to create two distinct flow chambers, lumen and extracapillary, each with inlet and outlet port access. The semi-permeable hollow fiber membrane that separates the two chambers selectively permits passage based on size and concentration gradient of solutes while restricting other solutes from passing between the 2 chambers. By operating the module in a counter-current flow mode, the solutes passing through the membrane are quickly swept away and diluted into a large volume of dialysate solution ("sweep"), maintaining the largest concentration gradient possible.

QUICK & EFFICIENT DIALYSIS!
  • Complete Dialysis in Hours
  • Dialysis of 100 mL to Multi-liter Samples
  • Achieve Higher Purities
  • Concentration of Fragile Samples
Majo Design Features
  1. Hollow Fiber Membrance Geometry
    Drastically larger surface area increases the rate of dialysis
  2. Inlet / Outlet "Flow-stream" Connection Ports
    Dialysis of multi-liter volumes of sample & dialysate
    Dialysate to drain connection for single pass sweep
    Static encapsulation of delicate sample in extracapillary chamber
  3. Counter-current "Flow-stream" Design
    Prevents membrane polarization & fouling
    Continuous mixing & suspension of sample & dialysate
    Maintains the largest concentration gradient possible
    Highest mass transfer rate significantly reduces dialysis time
