Vivaflow®

Vivaflow^® is the original plug-and-play tangential flow filtration (TFF) solution for handling samples up to 5 L in research and development laboratories.

For feed volumes of 100 mL and more, concentration and buffer exchange using centrifugal ultrafilters is cumbersome, labor intensive and time consuming, leading to a decrease in productivity. However, TFF based on scale-down process technology is expensive, complicated and requires additional effort in process optimization.

A trusted partner in separation workflows for a quarter of a century, Vivaflow^® features an all-in-one design with a unique switchback flow path that enables fast, low effort ultrafiltration and diafiltration using a standard pump. A choice of two membrane areas in multiple MWCOs suits many common sample types. The cassettes are also suitable for multiple runs without the need to replace the membranes, supporting greater process economy.

Supplied complete with a tubing kit, each cassette can be set up and run individually in ultrafiltration mode right out of the box. In addition, an enhanced selection of predefined tubing kits is available when tubing replacement, diafiltration, or running two cassettes in parallel is required.

If you are interested in a single-use option, Sartorius also offers Vivaflow® SU, which makes lab-scale TFF even more intuitive, effortless and sustainable.
