Polyvinylidene Fluoride Membrane vs. NC: What is Best?
When considering a membrane for separation applications, a key choice focuses around the substance: particularly PVDF (Polyvinylidene Fluoride filter) or NC. Nitrocellulose provides great molecule attachment capabilities, which makes it appropriate for processes including protein analysis . Nevertheless , PVDF filters usually exhibit greater chemical stability, leading to more for more demanding procedures or if using strong solvents .
- PVDF filter: High solvent resistance .
- Nitrocellulose filter: Good molecule binding .
