Membrane ultrafilter Vivaspin® Endotest

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 Certified pyrogen free for the concentration of endotoxin and removal of interfering substances from 4 – 15 mL samples prior to LAL testing. Vivaspin® Endotest is an easy to use tool for fast and reliable endotoxin concentration, and removal of interfering substances prior to the LAL test. It is a centrifugal ultrafiltration device which can handle volumes from 2 to 15 mL Sample preparation for the LAL test typically takes only 20 minutes. Vivaspin® Endotest can be operated in any centrifuge accepting 50 mL conical bottom tubes.
