Polyvinylidene Fluoride Membrane vs. Nitrocellulose : What is Best?
When choosing a filter for separation applications, a key factor revolves around the substance: specifically PVDF (Polyvinylidene Fluoride membrane ) or Nitrocellulose . Nitrocellulose delivers excellent protein adhesion capabilities, which makes it ideal for scenarios such as protein analysis . Yet, PVDF filters typically exhibit greater reagent durability , leading to more for harsher environments or when working with harsh solvents .
- PVDF filter: High reagent resistance.
- Nitrocellulose filter: Good macromolecule binding.
