Centrifuge filter device is seated inside centrifuge tubes to filter samples during during centrifugation.  This 15ml centrifugal filter devices provide rapid and efficient concentration and purification of up to 15.0 ml of biological samples. The unique vertical design and maximum filtration area provide fast sample processing and high sample recovery rate (typically greater than 90% of dilute starting solution), while maintaining a gentle concentration environment to preserve protein activity and conformation. Solute polarization and subsequent fouling of the membrane are minimized by the vertical design, and a physical dead-stop in the filter device prevents spinning to dryness and potential sample loss. The wide selection of ultra filtration molecular weight cut-off (MWCO) devices incorporate PES membrane, which is very low in protein and nucleic acid binding.

Key Features

• Low biological binding and high chemical compatibility
• Special design to prevent drying, which can avoid damage to the samples due to excessive centrifugation
• Optional pore sizes for various MWCO requirements
• Effective filtration area up to 7.2cm^2, larger area allows higher flowrate
• 100% pass integrity testing

Typical Applications

• Concentration/Desalination of Proteins/Nucleic Acids;
• Buffer Exchanging or Chromatography Component Desalting;
• Bio-molecules Harvesting from Culture Media;
• Concentration/Separation of Viruses;
• Coarse Separation of Bio-molecular Mixtures;
• Removal of Particles and Debris from Celllysate;
• Removal of Primers, Adapters, or Molecular Markers from Reaction mixtures.
