Downstream Filtration Products

Filtration in bioprocessing aims to remove unwanted substances (such as cell debris, viruses and bacteria) from cell media and other downstream processes, to filter out the Active Pharmaceutical Ingredients (API).  

The most common filtration applications are ultrafiltration and diafiltration using tangential flow filtration (TFF). Current needs include single-use, higher-capacity, higher-performance filters based on new materials, membrane structures, and filter designs,

Repligen provides high-performance, expertly engineered  integrated TFF systems, hollow fiber filters and flat sheet cassettes, and real-time process management and integrated single-use flow paths.

Repligen also provides hands-on process and implementation consultation from global Field Applications Specialists.
