Vivaspin 15

Vivaspin 15 centrifugal concentrators are disposable ultrafiltration devices for use in swing bucket rotors accommodating 50 ml tubes. Vivaspin 15 is used for the concentration of biological samples in the 2 - 15 ml range. The patented, innovative design (US 5,647,990, second patent pending), ease of use, speed and exceptional concentrate recovery are the main features of the concentrator. In a single spin, 15 ml solutions can be concentrated up to 300-fold. Sample concentration is typically completed in 10-30 minutes with macromolecular recoveries in excess of 95%. The vertical membrane and adjacent thin channel design provide optimum flow conditions even for particle- laden solutions, the centrifugal force pulling particles and solids away from the membrane. Macromolecules are collected in an impermeable 50 µl concentrate pocket integrally moulded below the membrane surface (dead stop), thereby eliminating the risk of filtration to dryness. Vivaspin 15 concentrators are available with the high flux PES membrane, covering a wide range of MWCO’s.
