Membrane Pretreatment Solutions

While rinsing Spectra/Por® dialysis membrane in water is typically sufficient to remove glycerine or preservative, Spectrum offers two membrane pre-treatment solution kits for the removal of trace levels of heavy metals and 0.1% sulfide introduced during the manufacturing process of Spectra/Por 1, 2, 3, 4, 5 & 6. (Note that Spectra/Por 7 is already pre-treated.) Heavy Metal Cleaning Solution Kit and Sulfide Removal Solution Kit are recommended for ultrasensitive dialysis applications like binding studies and equilibrium dialysis or when the low level presence of these contaminants may interfere with subsequent analyses of the dialysis samples.
