Vivaspin 15 Catalogue
2 - 15 ml samples
The Vivaspin 15 concentrator is a disposable ultrafiltration device for use in fixed angle or swing bucket rotors accommodating 50 ml tubes. Vivaspin 15 is used for the concentration of biological samples in the 2 - 15 ml range. The innovative design (US Patent no. 5,647,990, second patent pending), simplicity, speed and exceptional concentrate recoveries are the main features of the concentrator.
In a single spin, 15 ml solutions can be concentrated up to 300x. Samples can be typically concentrated in 10-30 minutes with macromolecular recoveries in excess of 95%. The longitudinal membrane location and adjacent thin channel, provide optimum cross flow conditions even for particle laden solutions, the centrifugal force pulling particles and solids away from the membrane to the bottom of the device. Macromolecules collect in an impermeable 50 µl concentrate pocket integrally moulded below the membrane surface, thereby eliminating the risk of filtration to dryness.
