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.
Spectra/Por HF Dialysis Modules are available in two performance
types: "High Performance" (HP) Membrane offers much higher flux
rates to significantly reduce the total time for dialysis, while "Standard
Performance" (SP) helps control the effects of osmotic pressure to reduce
sample dilution and high turgor pressures in high salt conditions.
- Hollow Fiber Membrane Geometry
Drastically larger surface area increases the rate of dialysis
- 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
- 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
- Two Membrane Performance Types
HP for increased membrane flux
SP for better control of osmotic pressure effects
