Membrane ultrafilter Vivaspin® 20

for liquidsgasair

Vivaspin® 20 and 100 can be used for centrifugal or pressurized concentration of samples with initial volumes from 5 to 100 mL. The vertical membrane design and unique methods of operation guarantee the highest performance while benefiting from maximum process control and flexibility. With an easy-to-use range of accessories, positive pressure applied from a compressed air or inert gas source can be used as the driving force for ultrafiltration. Pressurization is an ideal method for concentrating single samples on the bench, or sensitive target molecules such as membrane proteins, viruses, or multi-subunit complexes. A unique range of accessories for Vivaspin® 20 has been designed to allow ultrafiltration driven by positive pressure. For sensitive samples, Vivaspin® 20 can be pressurized for gentle, centrifuge free, bench-top concentration. Alternatively, the compact pressure-head ensures pressurization can be combined with centrifugation. With pressure-fugation, which is especially suited to viscous and particle loaded samples, or concentration at lower temperatures, process times can be substantially reduced. High speed concentration of 5 – 20 mL samples Centrifuge, pressure or pressure-fugation Maximum concentration factors with a single, low volume dead-stop pocket Concentrate any target with 3 – 1,000 kDa MWCO or 0,2 µm pore size options Ultrafiltration unit with unique twin membrane for sample concentration with high process flexibility: centrifugation or centrifugation of pressurized units, as well as pressure filtration in stationary benchtop mode.
