Membrane ultrafilter Vivaspin® 15R

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 Hydrosart® membranes provide optimal flux while ensuring minimal fouling and target adsorption for 4 - 15 mL samples. Top Features Avoids membrane fouling with crossflow technology for low-volume samples Increases recovery of valuable molecules, thanks to low absorption membranes Speeds up your concentration process with a high flux design Simplifies retentate retrieval with the pipette friendly dead-stop pocket Popular Applications Macromolecule concentration Desalting Buffer exchange Overview Vivaspin® 15R is recommended for 2 to 15 mL sample volumes and is compatible with swing bucket and fixed angle rotors accepting 50 mL centrifuge tubes.
