Caution
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. Because
chemical compatibility is affected by many
variables (including temperature, pressure,
concentration, and purity), various chemical
combinations prevent complete accuracy.
Ketones
R = Resistant
Alcohol residues that are allowed to dry on a filter may cause
stress cracks. Pall Corporation 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.
No significant change was observed in flow rate or bubble
point of the membrane. No visible indication of chemical
attack was detected.
L = Limited Resistance
Moderate changes in physical properties or dimensions of the
membrane were observed. The filter may be suitable for short
term, non-critical use. Hardware or housing may be suitable for
short-term exposure at low pressures and ambient temperatures.
N = Not Resistant
The membrane or housing is basically unstable and is not
recommended for use.
- = Insufficient Data
Information is not available. Trial testing is recommended.
chemical compatibility
The data presented in this chart is a
compilation of testing by Pall Corporation
with certain chemicals, manufacturer’s data,
or compatibility recommendations from the
Compass Corrosion Guide by Kenneth M.
Pruett. This data is intended to provide
expected results when filtration devices are
exposed to chemicals under static conditions
for 48 hours at 25 °C (77 °F), unless otherwise noted. Membrane integrity for syringe
filters was tested by bubble point.
