As Vivaflow SU is designed to ensure enhanced ease of use and flexibility, Sartorius needed a pump with similar qualities.
Peristaltic pump technology has proven to be particularly suitable and removes the risk of sample contamination during the TFF process as only the tubing is in contact with the process fluid.
