Sartorius ultrafiltration centrifugal concentrators
Spin to win – Versatile protein concentration solutions
With their broad range of volume capacities and MWCOs, Sartorius ultrafiltration centrifugal concentrators offer the optimal solution to any concentration or buffer exchange application. Our patented dead-stop technology allows direct sample recovery of the concentrate and prevents the sample from drying out. The easy to read printed scale simplifies calculation of concentration result. There is simply no safer or easier way to concentrate your sample.
- Vertical, large membrane design for fast processing & high recoveries
- From 0.5 – 20 ml for Broad volume flexibility
- Wide MWCO range from 2 kDa – 0.2 μm for super size flexibility

Sartorius Vivaspin® 15R ultrafiltration concentrators with Hydrosart® membrane for 4 to 15 ml Samples
Vivaspin® 15R features a modified regenerated cellulose membrane, Hydrosart ®, ensuring ultra low protein binding and superior recovery. Vivaspin® 15R comes with all the advantages of the Vivaspin family you’ve come to expect like swinging bucket or fixed angled rotor use, ultrafast concentration times (>2 mL/min.), very low hold-up volumes (< 20 μl), and patented dead-stop volumes (30 μl) for safety.
- 3.9 cm2 active membrane area
- Easy scale-up to Vivaflow 200 for volumes up to 5 liters
“Pressure-fugation” For even faster processing times!
Sartorius Vivaspin® 20 ml ultrafiltration centrifugal concentrators for 5 ml to 20 ml samples
Vivaspin® 20 is available with unique accessories designed to allow the combination of both centrifugal force and pressure. For delicate samples, Vivaspin® 20 can be pressurized for centrifuge free, gentle bench-top concentration. Or choose to speed up your process times with the pressure fugation option, especially suited for difficult to filter viscous samples or concentration at low temperatures.
- 6 cm2 active membrane area
- Available with 3 kDa to 0,2 µm MWCO
Unique design for complex biological samples
Ultrafiltration the Centrisart® way, only from Sartorius
Centrisart® I* is a ready-to-use unit for small-volume (≤ 2.5 mL), centrifugal ultrafiltration designed to separate proteins from low molecular weight substances in biological samples. Centrisart® I features a unique design that enables ultrafiltration in the direction opposite to centrifugal force. This method is extremely effective in preventing premature blockage of the filter, so effective that even whole blood samples can be deproteinized.
- Perfect for small (≤ 2.5 mL) samples
- 0.79 cm2 active membrane area, 100 µl dead-stop volume

Vivacon® 500 & Vivacon® 2 ultrafiltration centrifugal concentrators for 0.5 to 2 mL samples
The Vivacon® ultrafiltration filters are particularly suited for the concentration and desalting of DNA molecules but show an excellent performance for aqueous protein solutions too. For delicate and DNA sensitive tasks the Vivacon® 500 and Vivacon 2 PCR Grade units have been treated with ethylene oxide (ETO) in a validated process to remove traces of DNA and prevent interference with downstream applications.
- Hydrosart® MWCO membranes for minimal sample binding
- PCR validated, trace DNA-Free
