Vivaspin™ 15
Vivaspin™ 15 is used for the concentration of biological samples in the 2mL to 15mL range. In a single spin, 15mL solutions can be concentrated up to 300X. Sample can be typically concentrated in 10min to 30min 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 50mL concentrate pocket integrally molded below the membrane surface, thereby eliminating the risk of filtration to dryness.
Vivaspin™ 15R
Vivaspin™ 15R is used for volumes 2mL to 15mL with a modified regenerated cellulose membrane, Hydrosart™. This membrane is ideal where extremely high recovery with very low absorption is needed, for example in applications such as desalting and concentration of Ig fractions.
  • Ultimate recovery at low absorption (95 to 98%)
  • Extremely short concentration time (30X in 15min)
  • Convenient application protocol with easy handling
  • Easy scale-up to Vivaflow™ 200 with Hydrosart™ membrane for volumes up to 5L
  • Very small hold up volume (<20μL)
Vivaspin™ 500 (100μL to 500μL)
500μL centrifugal filter units offer a simple, one step procedure for sample preparation. For fixed angle rotors accepting 2. 2mL centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber minimises membrane fouling and provides high speed concentration, even with particle laden solutions.
Vivaspin™ 2 (0.4mL to 2.0mL)
Combines the speed of the classic Vivaspin™ products with low internal surface and membrane area for superior recoveries from very dilute solutions. With Vivaspin™ 2 there is a choice of directly pipetting the concentrate from the dead stop pocket built-into the bottom of the concentrator, or alternatively reverse spinning into the concentrate recovery cap which can then be sealed for storage. Both methods result in near total concentrate recoveries.
Vivaspin™ 4 (1mL to 4mL)
Vivaspin™ 4mL concentrators are disposable ultrafiltration devices for the concentration of biological samples. Maximum initial sample volume range from 1mL to 4mL. They can be effectively used in either swing bucket or fixed angle rotors accepting 15mL centrifuge tubes. The patented vertical membrane design and thin channel filtration chamber minimises membrane fouling and provides high speed concentrations, even with particle laden solutions. Vivaspin™ 4 is available with the high flux polyethersulfone membrane range that is recommended for most solutions.
Vivaspin™ 6 (2mL to 6mL) and Vivaspin™ 20 (5mL to 20mL)
Developed to offer increased volume flexibility and performance compared to 15mL products. Both products feature twin vertical membranes for unparalleled filtration speeds and 100 plus concentrations. Remaining volume is easy to read off the painted scale on the side of the concentrator and the modified dead stop pocket further simplifies direct pipette recovery of the final concentrate. Vivaspin™ 20 can also be used as a pressure-fugation system. This is a unique Vivascience™ method that combines gas pressure with centrifugation. This can reduce process time up to 50%.
