Polyvinylidene Fluoride Filter vs. Nitrocellulose : What are Best?
When selecting a filter for separation applications, a crucial choice focuses around the substance: particularly PVDF (Polyvinylidene Fluoride membrane ) or Nitrocellulose . Nitrocellulose delivers great macromolecule adhesion capabilities, making it ideal for scenarios such as protein analysis . However , PVDF filters typically exhibit greater reagent resistance , making them more for harsher procedures or when working with aggressive chemicals .
- PVDF filter: High chemical resistance .
- Nitrocellulose membrane : Good protein binding .
