Selection Guide & FAQs for Filter Membrane Choice

1. How do I select the right pore size?

• Use 0.22 µm or 0.2 µm for sterile filtration of solutions (removes bacteria and most microorganisms).
• Choose 0.45 µm for clarification, particle removal, or general analysis.

2. Which membrane should I use for proteins or sensitive biological samples?

PES and PVDF membranes are preferred due to their low protein binding and minimal extractables.

3. Can these filters handle organic solvents?

PVDF and PTFE membranes are excellent for aggressive or organic solvents, while MCE and PES are better suited to aqueous solutions.

4. How should I store unused filter membranes?

Store in a dry, room-temperature environment, away from direct sunlight and corrosive vapors. Sealed packaging extends shelf life and sterility.

5. Are sterile membranes required for all applications?

Sterile membranes are essential for cell culture, clinical, or critical QA workflows, but non-sterile options are suitable for general analytical or research tasks.
