Sartorius’ Vivaflow SU tangential flow filtration (TFF) is designed to be more user-friendly and to allow for more flexibility in laboratory workflows. The new cassette offers more efficient and sustainable ultrafiltration and diafiltration processes for feed volumes in the range of 100 mL–1000 mL. Vivaflow SU is an all-in-one cassette, which reduces cost and complexity and streamlines workflows for molecule isolation. Each cassette is ready to use and has a standard laboratory pump for simple set-up, which avoids the need for expensive systems and expensive process optimization. It also allows for faster and more reliable concentration and rebuffering of any molecule. The cassette eliminates the need for cleaning and reduces contamination risk while minimizing waste. Sustainability features include a new housing that uses 30.5% less plastic. It also incorporates several eco-friendly design improvements, such as locally sourced raw materials, customized tubing kits for each cassette configuration, a digital user manual, and reduced non-recyclable packaging; all of which are meant to contribute to a lower research footprint. Vivaflow SU is the-next-generation TFF cassette that replaces the previous Vivaflow 50 model. It is applicable for research scientists who require a fast and reliable means for concentrating and rebuffering large feed volumes in molecule isolation workflows.
