Vivaspin™ sample concentrators are designed for fast, nondenaturing concentration of biological samples by membrane ultrafiltration. Up to 30-fold concentration of the sample can be achieved with recovery of the target molecule typically exceeding 95%. The entire process is performed in a single tube with an upper compartment containing sample and a lower compartment separated by a semi permeable membrane with a molecular weight cutoff (MWCO) selected by the user. Centrifugation is applied to force solvent through the membrane, leaving a more concentrated sample in the upper chamber.

  • High recovery rates - up to 30-fold concentration of the sample can be achieved, with recovery of the target molecule typically exceeding 95%
  • Sample protection - the patented Vivaspin dead-stop technology ensures samples cannot be concentrated to dryness and enables direct concentrate recovery
  • Ease of use - one-step sample concentration in a single tube, for minimal sample handling and reduced sample loss
  • pH compatibility - for a broad range of pH 1 to 9
  • High flow rates - and minimal membrane blockage through the vertical polyethersulfone (PES) membrane design
  • Minimal protein adsorption - thanks to the Vivaspin™ polycarbonate tube design
