Membrane ultrafilter Vivaspin® Filtrate

for liquidscentrifugeintegrated

With the most comprehensive range of centrifugal concentrators, comprising 12 device types, Sartorius offers the optimal solution to any ultrafiltration or buffer exchange application. The Vivaspin® and Vivacon® families provide a wide choice of sample capacities, membrane materials and MWCOs. Large active membrane areas and integrated dead-stops ensure maximum process speeds, highest concentration factors and direct concentrate retrieval, while avoiding sample loss through concentration to dryness. The easy-to-read printed volume graduations simplify monitoring of ultrafiltration progress. In addition, unique pressure, continuous diafiltration and reverse ultrafiltration methods allow for processing of even single, sensitive, or challenging samples. There is simply no safer or easier way to concentrate, desalt or re-buffer your target molecule. Rapid concentration and diafiltration Process initial samples between 0.1 and 100 mL Unrivalled process flexibility A membrane and MWCO range to suit any target Performs ultrafiltration in the opposite direction to centrifugal force, ideal for ultrafiltrate applications with 0.5 – 2.5 mL samples. The unique design of Vivaspin® Filtrate ensures that the ultrafiltrate is collected above the membrane, ready for direct retrieval and analysis. Top Features of Vivaspin® Filtrate: Unhindered passage of low molecular weight solutes prior to ultrafiltrate analysis Rapid protein removal from biological samples Recover your sample directly, without the need to remove any caps or disassemble the unit Popular Applications for Vivaspin® Filtrate: Separation of free- from protein-bound drugs or hormones
