Sartorius Filtration Case Study – mAb Production Scale-Up

Challenge: A CDMO scaling from clinical to commercial batch size experienced inconsistent flow rates and fouling of chromatography columns.

Solution: Implemented:

• Sartoclear Dynamics® for depth clarification

• Sartopore® 2 XLM for sterile filtration

• Virosart® HF for virus removal

Outcome:

• 30% improved filter throughput

• Resin life extended by 25%

• Process time reduced by 2 days per batch

Regulatory Compliance & Validation

All Sartorius biopharma filters are:

• ✅ Validated for microbial retention (e.g., B. diminuta, MS2 bacteriophage)

• ✅ Accompanied by validation dossiers and extractables/leachables data

• ✅ Compliant with USP <788>, USP <85>, Ph. Eur., and ICH Q6B

• ✅ Supported by global technical services for on-site validation and scalability testing
