Innovative and high quality concentrator device.
Application Area: Concentration of Urines for Sebia Capillary Electrophoresis
"The Vivaspin from Sartorius perform high quality concentration of urine samples for the quantitation of proteins using Sebia Capillary Electrophoresis. The tubes are made of high quality plastics with screw lids which stay sealed during centrifugation. They have an innovative design which allows for the capture of microparticles beyond other concentrators. They are easy to decant and easy to read. Customer service from the company and sales is very responsive and knowledgeable."

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!"
Classical concentration and buffer exchange methods are labor intensive, generate excessive waste and suffer from sample loss and long process times. It can also be difficult to retrieve retentate samples from centrifugal ultrafilters when using standard pipette tips. To overcome these challenges, Sartorius has developed Vivaspin® Turbo - the ultimate range of centrifugal ultrafilters. These feature highly optimized designs and membrane options to offer the highest processing speeds, maximum biomolecule recoveries, and straightforward retentate retrieval.
