Nanofiltration Membrane 8040(NF2)

Brief introduction:

Nanofiltration membrane 8040(NF2): High rejection rate for multivalent ions, low rejection rate for monovalent ions, accurate molecular weight interception, and also suitable for the separation and purification of small molecule pharmaceutical drugs.

Special grid design is adopted in the inlet channel, which makes the product advantageous in pollution resistance and cleaning.
