Vivaspin® Filtrate Centrifugal Ultrafilter Sartorius

Vivaspin® Filtrate Centrifugal Ultrafilter is a ready-to-use unit for centrifugal ultrafiltration of small samples to separate proteins from low molecular weight substances in biological samples. Vivaspin® Filtrate Centrifugal Ultrafilter  embodies a unique design: ultrafiltration against centrifugal force. This principle prevents premature membrane blocking so effectively that even whole blood samples can be deproteinised. Centrisart I can be used in swing-out rotors or fixed-angle rotors for 15 ml standard tubes. Ultrafiltration of 90% of the original sample is typically completed in about 30 minutes. The ultrafiltrate is collected inside the float tube and can be easily removed without having to take out the tube. Separation of proteins from biological samples is a critical step for e.g. drug binding studies or determination of metabolites in serum.

Typical applications include:

• Drug binding studies
• Determination of metabolites in serum
• Protein removal from blood samples
• Purification of liposomes, virus removal
• Centrifugal ultrafiltration against centrifugal force
• Separation of proteins from biological samples, even from whole blood
• Quick and easy recovery of protein-free ultrafiltrate
• Wide range of MWCO
