Specifically designed to process cell culture media, Viresolve® Barrier filters are the last line of defense against bioreactor contamination. These filters have demonstrated high retention of virus, mycoplasma and bacteria, including spirochetes, while providing high flow and capacity.
Robust protection from adventitious agents
- ≥ 3.0 log removal of parvovirus
- ≥ 6.0 log removal of mycoplasma
- Sterilizing-grade protection from bacteria
- 100% integrity tested in manufacturing, ensuring quality and consistency
Efficient virus filtration for cell culture media
- No impact to cell culture media performance
- High-flux virus filtration
- Easy to implement, install and integrity test
- Scalable from preclinical through commercial manufacturing
The Emprove® Program
The Emprove® Program complements the product portfolio through
- Comprehensive documentation to support qualification, risk assessment and process optimization needs.
- Consolidation of product specific testing, quality and regulatory information to simplify compliance requirements.
- Convenient 24/7 access to up-to-date product information.
