Polyvinylidene Fluoride Membrane vs. NC: What are Best?
When choosing a membrane for filtration applications, a key factor centers around the substance: specifically PVDF (Polyvinylidene Fluoride membrane ) or Nitrocellulose . Nitrocellulose provides superb protein attachment capabilities, which makes it well-suited for applications like molecular detection. Yet, PVDF membranes typically exhibit superior reagent resistance , which makes them better for harsher conditions or if using harsh reagents.
- PVDF filter: High reagent resistance.
- Nitrocellulose filter: Good macromolecule binding.
