PVDF Filter vs. Nitrocellulose : What are Best?
When choosing a membrane for separation applications, a crucial decision revolves around the media : more info particularly PVDF (Polyvinylidene Fluoride membrane ) or NC. Nitrocellulose provides superb protein binding capabilities, leading to appropriate for applications like molecular detection. Yet, PVDF filters typically exhibit greater chemical durability , making them more for harsher environments or in cases involving harsh reagents.
- PVDF filter: High solvent resistance .
- Nitrocellulose filter: Good macromolecule binding.
