Analytical Ultracentrifuge (AUC)

Beckman Proteomelab XL-I

Main Technical Features

  • The Xl-I is equipped with UV/Vis detection system to measure absorbance and with Rayleigh Interference Optics to measure the change in refractive index resulting from changes in sample concentration.
  • Up to 21 different sample/reference pairs can be studied in a single run.
  • The sample can be recovered for additional analysis.


  • Sedimentation Equilibrium experiments are mostly intended to measure molecular weight and intermolecular association constants of the species in solution.
  • Sedimentation Velocity experiments are intended to measure sedimentation coefficients and hydrodynamic parameters of the species in solution.
Rates & Fees:
