    • Q:

      I've purchased these filters, and I've tried using them, but my liquid media doesn't seem to go through the filter. Gas goes through the filter, but liquid doesn't seem to go through.

      • STAFF EXPERT

        A:

        PTFE Filters are hydrophobic. Aqueous solutions will likely have issues. You may want to research pre-wetting the membrane with an organic solvent before use with aqueous fluids.
