Vivaspin® 20 handles up to 20 ml in swing bucket rotors and 14 ml in fixed angle rotors accepting 50 ml centrifuge tubes. Vivaspin® 20 features twin vertical membranes for unparalleled filtration speed and 100-fold concentration. Volume graduation allows monitoring the concentration process and the modified dead stop pocket simplifies pipetting of the final concentrate. For higher process flexibility. Vivaspin® 20 is available with unique accessories and operating methods. For one-step desalting following concentration. a diafiltration cup filled with buffer is can be placed on the concentrator and spun another time to achieve 98% salt removal. instead of two spins to achieve the same result with the traditional refill and re-spin procedure. When an appropriate centrifuge is unavailable. or for single sample processing. for gas pressure filtration. Vivaspin® 20 can be filled with up to 15ml and then pressurised for bench top concentration. For even faster processing. gas pressure filtration can be combined with centrifugation. 'Pressure-fugation' is particularly useful for difficult or viscous samples such as serum. when using a low process temperature. or generally when minimum process time is essential.

These devices are not designed to fit into rotors that only accept round bottom 29 mm x 105 mm tubes. e.g. Sorvall SS34 or Beckmann JA 20. If your rotor accepts only 29 mm x 105 mm round bottom tubes. please use the Vivaspin® Turbo 15. which can be used in either round bottom or conical centrifuge tubes     Performance Characteristics                                  Time to concentrate up to 30x [min.] at 20°C      and solute recovery %                         Mode           Centrifuge           Centrifuge           Bench top           Press-fuge                   Rotor           Swing bucket           25° Fixed angle           Pressure           Swing bucket                   Sart volume           20 ml           14 ml           10 ml           10 ml                               Min.\/Rec.
