Electron Spin Resonance ESR Apparatus

This Electron Paramagnetic Resonance (EPR) experiment system is designed to demonstrate the fundamental principles of electron paramagnetic resonance and magnetic resonance spectroscopy. It enables students to study EPR phenomena, measure the Landé g-factor, determine the resonance linewidth of DPPH samples, and gain practical experience in magnetic resonance measurement techniques. The system includes a frequency meter for accurate frequency measurement. Note: Oscilloscope is not included. Manufactured by Atico Export India.
