FAQ
What are PVDF syringe filters used for?
PVDF syringe filters are used for organic solvent filtration, gas filtration, and biological sample preparation, especially in HPLC and pharmaceutical analysis.
Are PVDF filters hydrophobic?
Yes. Hydrophobic PVDF filters repel water and are ideal for non-aqueous samples and gas filtration.
Can PVDF filters be used for proteins?
Yes. PVDF membranes have low protein binding, making them suitable for antibodies and enzymes.
What is the difference between PVDF and PTFE filters?
PVDF offers low protein binding and broader biological compatibility, while PTFE is mainly used for strong solvents and gases.
What pore size should I choose?
- 0.22 µm → Fine filtration / sterile prep
- 0.45 µm → General filtration
- 1.0 µm → Pre-filtration
