Sartorius Stedim Biotech presents Virosart Media

With this new media filter, the company says it offers a fast and cost-effective solution for manufacturers to reduce the risk of virus contamination resulting from raw materials, such as chemically defined media, during fermentation.Virosart Media is a single-use filter that provides the highest level of safety for customers’ upstream processes as it is qualified for > 4 log10 reduction of small, non-enveloped viruses (e.g., MVM) and as a mycoplasma and leptospira retentive filter.A major benefit of this new filter is that mid-scale and process filters of the Virosart Media product family will also be qualified as a sterile filter based on the current ASTM guideline. The first product of the Virosart Media family is a lab filter with a filtration area of 5.0 cm2 for down-scale, flow and capacity studies. The mid-scale filter with 0.29 m² and the process filters with 1 m² and 3 m² will follow in the second half of 2016.

Virosart Media family: First risk-mitigating virus-retentive filters for cell culture media.

By launching Virosart Media filter, SSB rounds out customers’ individual risk mitigation strategy in upstream processing with an additional option: With the filters Sartopore 2 XLG (0.2 μm) for sterile filtration, Sartopore 2 XLM (0.1 μm) for retention of mycoplasma and with its new Virosart Media filter (20 nm) for virus retention, SSB enables customers to mitigate risk at three different levels.
