Concentrate samples in the 15 mL-70 mL volume range using Centricon® Plus-70 centrifugal filter units. The large deadstop volume of 350 µL prevents spinning samples to dryness. The Centricon® Plus-70 has two vertical regenerated cellulose membranes for fast, efficient tangential flow. The device is available with four different pore size membranes (3, 10, 30 and 100 kDa NMWL).
Applications
Concentration and Desalting of Chromatography Column Eluates, Concentrating Monoclonal Antibodies, Concentrating Proteins or Viruses From Culture Supernatants, Clarifying Tissue Homogenates and Lysates, Buffer Exchange or Diafiltration
