Chemical compatibilities can be influenced by various factors. Therefore, we recommend that yo u confirm compatibility with the liquid you want to filter by performing a trial filtration run before you start your actual filtration.

The information in this chart has been supplied to Cole-Parmer by other reputable sources and is to be used ONLY as a guide in selecting equipment for appropriate chemical compatibility. Before permanent installation, test the equipment with the chemicals and under the specific conditions of your application.

All-purpose, universal hydrophilic polypropylene membrane with maximum chemical compatibility when filtering both aqueous solutions and aggressive solvents. Low protein binding of GH Polypro membrane provides high recovery of critical proteinaceous samples.

PES membranes were exposed to the following chemicals for 48 hours. If there was no significant change in the bubble point, strength or appearance of the membrane, it was judged compatible with the chemical. If the membrane dissolved, or otherwise lost its strength, or changed significantly in appearance, it was rated incompatible with the liquid.
