VISKING DIALYSIS MEMBRANE is resistant to a wide variety of chemicals and below is a list of common substances and their likely effects on the membrane. This is clearly not an exhaustive list and we would be grateful to hear from you if you have used other substances and found them to affect the membrane in some way, please e-mail us with your experiences and we will update the list.

For further information as well as tolerances for the regenerated membranes (RC) we have included chemical tolerance information on Cellulose ester (CE), Polyvinylidine Fluoride (PVDF) and Polysulphone membranes.

KEY TO RATINGS:
G	GOOD TOLERANCE - UNLIKELY TO CAUSE MAJOR DYSFUNCTION OF THE MEMBRANE. ALTHOUGH TESTING IS NOT NORMALLY NECESSARY IT IS ADVISABLE.
P	POOR TOLERANCE - LIKELY TO CAUSE DISTORTION OR DENATURING OF THE MEMBRANE WHICH MAY RESULT IN LOSS OF MATERIAL AND POOR RESULTS. TESTING IS ADVISABLE.
F	FAIR TOLERANCE - THESE SUBSTANCES ARE LIKELY TO CAUSE DISTORTIONS IN THE MEMBRANE AND THEREFORE RESULTS MAY BE AFFECTED. WHEN MEMBRANES ARE USED WITH THESE SUBSTANCES IT IS IMPORTANT THAT TESTING IS CARRIED OUT TO ENSURE THAT THE EFFECT OF THESE SUBSTANCES IS KNOWN.
