Polyvinylidene Fluoride Filter vs. Nitrocellulose : What is Best?
When selecting a filter for separation applications, an important decision centers around the media : namely PVDF (Polyvinylidene Fluoride filter) or Nitrocellulose . Nitrocellulose provides great molecule attachment capabilities, leading to well-suited for processes including molecular detection. However , PVDF filters usually exhibit greater chemical stability, which makes them more for more demanding conditions or in cases involving harsh solvents .
- PVDF membrane : High chemical resistance .
- Nitrocellulose filter: Good macromolecule binding.
