HiPrep DEAE FF

• Cat#No#: Hi-205P
• Product Overview: HiPrep DEAE FF 16/10 is a weak anion exchanger prepacked with DEAE Sepharose Fast Flow, ready-to-use for fast, preparative separations of proteins and other biomolecules using ion exchange (IEX) chromatography.
• Characteristic: 20 mL HiPrep columns provide fast, reliable, and reproducible preparative ion exchange separations.
  Good flow rates and high capacity.
  The industry standard for ion exchange chromatography.
  Compatible with single-pump configurations and chromatography systems.
  Use a weak ion exchanger if the selectivity of a strong ion exchanger is insufficient.
• Maximum operating pressure: 1.5 bar [0.15 MPa] (22 psi)
• Sample preparation: 1. Adjust the sample to the composition of the start buffer, using one of these methods: Dilute the sample with start buffer. Exchange buffer using a HiPrep 26/10 Desalting, HiTrap Desalting or PD-10 Desalting column.
  2. Filter the sample through a 0.45 µm filter or centrifuge at 10 000 × g for 10 min immediately before loading it to the column. This prevents clogging and increases the life time of the column when loading large sample volumes.
