Polyvinylidene Fluoride Filter vs. NC: Which is Best?
When considering a filter for filtration applications, a key choice revolves around the substance: particularly PVDF (Polyvinylidene Fluoride filter) or NC. Nitrocellulose provides excellent molecule adhesion capabilities, which makes it appropriate for scenarios such as molecular detection. Yet, PVDF membranes generally exhibit enhanced reagent resistance , which makes them better for harsher procedures or when working with aggressive solvents .
- PVDF filter: High chemical resistance .
- Nitrocellulose membrane : Good macromolecule binding.
