machine

AKTA Purifier (GE Healthcare)

Fast protein liquid chromatography is often used to analyze or purify mixtures of proteins. Our FPLC system is located in the cold room and is equiped with a deep well block fraction collector.

Possible applications

  • Protein sample purification on site, SEC
  • Sample clean up before SAXS measurement
  • Equilibration of column prior to SAXS measurment using MALVERN-box

Provided vs not provided:

  • Deep well block are provided for fraction collection
  • Users should provide their own FPLC column and super loop if needed
