Sartorius Vivaspin® 2
Chromatography Columns
The Vivaspin 2 bridges the gap between the 500 µL and 4 mL centrifugal concentrators.

  • Choice of Three Membranes
  • Polyethersulfone Membranes Create Fast Concentrations
  • Cellulose Triacetate Is Ideal for Protein Removal/Ultrafiltrate Recovery
  • Hydrosart Membranes Create Highest Recovery with Ig Fractions
  • More than 90% Rententate Recovery

This device combines the speed of the classic Vivaspin products with low internal surface and membrane area for superior recoveries from dilute solutions

Polyethersulfone works well with most solutions when retentate recovery is of primary importance. Cellulose Triacetate is hydrophilic and low non-specific protein binding. Regenerated Cellulose is hydrophilic. Hydrosart has the same properties as Regenerated Cellulose with enhanced characteristics and extremely low protein binding. It's designed for antibody work.

Available with a choice of PES, Cellulose Triacetate, and Regenerated Cellulose (Hydrosart®) membranes, Vivaspin 2 offers the highest flexibility for process optimization. Also unique to the Vivaspin 2 is the 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.
