PVDF Membrane vs. Nitrocellulose : What are Best?
When selecting a membrane for filtration applications, a crucial choice centers around the material : particularly PVDF (Polyvinylidene Fluoride filter) or NC. Nitrocellulose provides great protein adhesion capabilities, which makes it appropriate for applications like western blotting . However , PVDF membranes usually exhibit greater chemical durability , which makes them more for rigorous procedures or when working with aggressive solvents .
- PVDF filter: High chemical resistance .
- Nitrocellulose filter: Good macromolecule binding.
