Analytical Biochemistry Core Facility Instrumentation
Beckman Analytical Ultracentrifuge 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.
Applications
- 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 and Fees
Hourly rates. These rates are in effect from July 1, 2009 through June 30, 2010, and are subject to change without further notice.

The XL-I rates are per day (24 hours) except training, which is an hourly rate.
These rates are for equilibrium exp.
The training and assisted rates are the same for equilibrium or velocity experience.
Velocity rates will be twice the above.
