Techniques for Demonstrating Cleaning Effectiveness of Ultrafiltration Membranes

A Case Study: Pellicon 2 Cassette Processing of Therapeutic Proteins

Lit No:TB1502EN00
Year:2001


Tangential flow filtration cartridges designed to isolate, purify and concentrate therapeutic biomolecules are typically reused for multiple process cycles. After each process run, the system is cleaned to remove foulants and contaminants from the membrane in preparation for the next cycle. To maintain optimal membrane performance, biotech and pharmaceutical manufacturers must establish effective, reproducible cleaning techniques to prevent microbiological contamination and ensure against cross contamination of batches.
