Centrifugal Ultrafiltration Devices
Centrifugal ultrafiltration devices for concentration and buffer exchange / desalting of proteins, DNA, viruses and other biological samples. Sartorius Stedim Biotech offers a choice of thirteen different centrifugal ultrafiltration devices covering sample volumes from 100 µl up to 100 ml with MWCOs from 3 kDa to over 1000 kDa for fast and safe sample processing. Choose between vertical and horizontal membrane configurations as best suited for your application.
Vivaspin® 6 is optimally suited for the concentration of antibody-, protein-, nanoparticle- and virus samples from 6ml sample volume to 30 µl in a centrifuge accepting 50ml conical bottom centrifuge tubes. Our premium PES membranes in the twin vertical membrane design, lead to fast sample concentrations and high recoveries. A built in dead stop pocket guarantees safe and complete concentrate recovery. The Vivaspin® 6 is the only device of its size that can operate 6ml sample.
0.4 - 2 ml
Three membrane alternatives: PES, Hydrosart® regenerated Cellulose, Cellulosetriacetat. Best recovery of the concentrate by reverse-spinning.
15 ml - 100 µl ultrafiltration unit with twin vertical membranes and sleek internal design for fastest sample concentration with highest recoveries. The pipette friendly dead stop pocket eliminates the risk of sample filtration to dryness and facilitates the recovery of the concentrate.
