PVDF Filter vs. Nitrocellulose : What is Best?
When choosing a filter for microfiltration applications, a key factor centers around the substance: particularly PVDF (Polyvinylidene Fluoride filter) or NC. Nitrocellulose delivers excellent protein binding capabilities, making it ideal for applications like molecular detection. Yet, PVDF membranes typically exhibit greater chemical resistance , which makes them more for rigorous procedures or if using harsh solvents .
- PVDF filter: High chemical resistance .
- Nitrocellulose membrane : Good molecule binding .
