Polyvinylidene Fluoride Filter vs. Nitrocellulose : What are Best?
When selecting a filter for filtration applications, a crucial factor centers around the media : specifically PVDF (Polyvinylidene Fluoride filter) or Nitrocellulose . Nitrocellulose offers superb molecule attachment capabilities, making it ideal for processes including molecular detection. Yet, PVDF filters generally exhibit superior chemical stability, leading to more for harsher environments or in cases involving harsh reagents.
- PVDF filter: High reagent resistance.
- Nitrocellulose membrane : Good macromolecule binding.
