WebPES 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. WebNational Center for Biotechnology Information
