FAQs & Expert Tips on Sartorius Filtration & Purification

Q: How do I choose the right membrane material?
A: For aqueous samples, RC and PES are preferred due to low protein binding. Use PTFE for aggressive solvents or gas filtration.

Q: What is the difference between syringe filtration and vacuum filtration?
A: Syringe filters are ideal for small-volume, quick processing, while vacuum units are best for high-throughput or large-volume filtration needs.

Q: How do I ensure sterility during filtration?
A: Always use pre-sterilized filters and work in a clean environment. Sartorius filters are certified for sterility and provided in individually wrapped packaging.

Q: What is the bubble point test?
A: The bubble point integrity test confirms membrane pore size and ensures the filter’s effectiveness, especially critical for pharmaceutical or sterile applications.
