Really pleased to find such a useful product.
Application Area: Concentrate and clean up protein extracts
"Easy to use - concentrated proteins quickly and effectively. The extracts can be washed easily - ideal for buffer exchange."

Good protein recovery for proteins larger than the molecular weight cut off.
Application Area:Concentrate protein solutions, and remove low molecular weight species
"Works well to concentrate a protein with a molecular weight above the cut off. Little sample loss even if cutoff is close to the molecular weight. Quite efficient at removing low molecular weight contaminants. Not very good at filtering through the species that have a molecular weight lower than the cut off. They seem to get stuck in the filter. It would be nice if there was a product that could act to specifically allow the lower molecular weight species to flow through as much as possible."

Excellent underrated protein concentrator
Application Area:Great value! Better than Millipore in recovery.
"These are excellent products, underrated compared to their competitors as they do not have the market penetration. Definitely recommended!"
Vivaspin® products offer a comprehensive range of devices for fast protein concentration from 0.5 ml to 20 ml volume capacities. The large range of different molecular weight cut offs, from 2 kDa to 1000 kDa and 0.2μm offer a solution to every concentration need. Unique Vivaspin 20 can be pressurized and centrifuged simultaneously for processing difficult samples.
