Chemical Compatibility Matrix

R	Resistant
LR	Limited Resistance
NR	Not resistant
-	Insufficient data

The data presented in this chart is a compilation of testing by Pall Life Sciences with certain chemicals, manufacturer's data, or compatibility recommendations from the Compass Corrosion Guide, by Kenneth M. Pruett. This information is provided only as a guideline and testing is recommended. This data is intended to provide expected results when filtration devices are exposed to chemicals under static conditions for 48 hours at 25 °C, unless otherwise noted.

Resistant. No significant change was observed
in flow rate or bubble point of the membrane.

Limited resistance. Moderate changes in
physical properties or dimensions of the
membrane were observed. The filter may
be suitable for short-term, noncritical use.

Not resistant. The membrane is unstable. In
most cases extensive shrinkage or swelling
occurs. The filter may gradually weather or
partially dissolve after extended exposure.

Note: Alcohol residues that are allowed to dry on a filter may cause stress cracks. Therefore, Pall Life Sciences recommends that filters used in alcohol processing should remain alcohol wet, or should be flushed with copious quantities of water to remove residuals prior to drying and subsequent reuse.

This chart is intended only as a guide. Accuracy cannot be guaranteed. Users should verify chemical compatibility with a specific filter under actual use conditions. Chemical compatibility with a specific filter under actual use conditions is affected by many variables including temperature, pressure, concentration, purity and various chemical combinations that prevent complete accuracy.
