The university has identified a need for an Upgrade of E500 CW X-band EPR spectrometer. The last upgrade was done in 2004 and is very outdated. The manufacturer does not support equipment which is more than 15 years old. This purchase will upgrades our  routinely used Electron Paramagnetic Resonance (EPR) spectrometer to perform continues waves (CW) EPR measurements in the X-band. The upgrade is urgently needed to maintain the high level of our scientific research and ensure continued service support from the manufacturer.
