Next-Generation TFF Cassette, Vivaflow® SU, Delivers Intuitive, Effortless, and Sustainable Ultrafiltration

The life science group Sartorius is launching Vivaflow® SU, setting a new standard for laboratory-dedicated tangential flow filtration (TFF). Designed for enhanced ease of use and flexibility, Vivaflow® SU ensures more efficient and sustainable ultrafiltration and diafiltration processes for feed volumes ranging from 100 to 1,000 mL.

Vivaflow® SU is a unique TFF cassette that reduces cost and complexity, streamlines molecule isolation workflows, and champions sustainability. Each all-in-one cassette is ready to use with a standard laboratory pump, enabling simple set-up, while avoiding the need for expensive systems and process optimization. It allows for faster and more reliable concentration and rebuffering of any molecule, eliminating the need for cleaning, reducing contamination risk, and minimizing waste.

“Vivaflow® SU is a testament to our promise to always simplify progress,” explains John Cashman, Product Manager for Lab Ultrafiltration at Sartorius. “It takes the ease of use that our customers already value about TFF with Vivaflow® and elevates the experience with improved handling and performance, while reducing waste. Our next generation cassette eliminates the need for feed flow rate, TMP, and permeate flux calculations, while also offering sustainability improvements that are truly impressive for a single-use consumable.”

By significantly reducing single-use waste compared to previous TFF cassettes, Vivaflow® SU demonstrates Sartorius' commitment to environmental responsibility. The new housing uses 30.5% less plastic and incorporates several eco-friendly design improvements, including locally sourced raw materials, customized tubing kits for each cassette configuration, a digital user manual, and reduced non-recyclable packaging, all contributing to a lower research footprint.

Vivaflow® SU replaces the long-standing and successful Vivaflow® 50, as the next generation TFF cassette for research scientists who need a fast and reliable solution for concentrating and rebuffering large feed volumes in their molecule isolation workflows.
