Technical data


ESR-NMR control panel (230 V, 50/60 Hz)

Article no: 09051-11

Function and Applications

ESR / NMR control panel for the investigation of electron spin resonance (ESR) on the unpaired electron of DPPH (diphenyl-picryl-hydrazyl) molecules as well as the nuclear magnetic resonance (NMR) for example on glycerol, polystyrene and Teflon. The resonances are monitored by high-frequency-induced transitions when the external magnetic field changes. The resonance absorption curves can be displayed with a simple two-channel oscilloscope.
The device consists of the following components:

  • 1 control console
  • 1 power supply unit (12 V AC (230V, 50 / 60Hz))

Equipment and technical data

  • Control panel:
    • Connection of measuring heads: four-pin lemo socket
    • Connection of coil pair: Sawtooth current source 0 - 250 mA, 50 ms, pair of hollow sockets
    • Output Field: proportional to the coil current, 0 to 1V, BNC socket
    • Output signal: Resonance signal, 0 to 1 V, BNC socket
    • Frequency range: approx. 45 to 75 MHz (ESR)
    • ca. 10 to 15 MHz (NMR)
    • H x W x D: 45 mm x 170 mm x 105 mm
    • Weight: approx. 1.05 kg
