Offers increased volume flexibility and performance. VivaspinTM 20 Centrifugal Concentrator handles up to 20mL in swing bucket rotors and 14mL in fixed angle rotors accepting 50mL centrifuge tubes. Features twin vertical membranes for unparalleled filtration speed and >100-fold concentration.
Vivaspin™ 20 centrifugal concentrators have been developed to offer increased volume flexibility and performance. Vivaspin™ 20 handles up to 20mL in swing bucket rotors and 14mL in fixed angle rotors accepting 50mL centrifuge tubes. Vivaspin™ 20 features twin vertical membranes for unparalleled filtration speed and >100-fold concentration. Volume graduation allows to monitor 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 placed on the concentrator and spun 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.
