Research Collaborate Lab Bench

National Biomedical EPR Center


Services at the National Biomedical EPR Center involve the entire complement of faculty and staff and, oftentimes, graduate students.

Our service activities are diverse in nature and include

  • Provision of engineering drawings, advice, and, in some cases, hardware;
  • Assistance with construction of EPR and sample-handling equipment;
  • Carrying out of HFSS simulations to assist in resonator design;
  • Provision of novel spin traps and synthetic methodology;
  • Recording and analysis of EPR spectra at 1–35 GHz;
  • Provision of advice regarding commissioning, testing, and maintaining of cryogenic equipment;
  • Matrix diagonalization computer simulations; and
  • Performance of rapid-freeze quench spectrokinetic experiments.

For general advice or to apply for EPR Center services, contact us or the faculty or staff member with whom you previously worked. 

EPR Spectrometer Availability

EPR spectrometers are available to experienced spectroscopists for studies that do no require professional staff assistance.

EPR Spectra from Samples

EPR spectra from samples submitted by mail will be obtained if the study is routine. If the study is not routine, a visit to the EPR Center is more appropriate.

Engineering Assistance

We provide assistance in creating various pieces of specialized EPR equipment. We also provide advice and (in many cases) mechanical drawings such as:

  • Numerous loop-gap resonators or cavity resonators as described in papers by members of the EPR Center
  • A holder for TPX capillaries in an Eppendorf centrifuge tube

Center engineers have extensive knowledge of Varian EPR spectrometers. They may be able to help you locate parts.

Our very well-equipped microwave laboratory is open to qualified users. Dr. Richard R. Mett has extensive experience in finite-element modeling of electromagnetic field in resonators.

Training Opportunities

Our training program was established to provide outside users with training in many areas of EPR spectroscopy.
