Benchtop Electron Spin Resonance (EPR/ESR) Spectrometer.

Benchtop Electron Spin Resonance (EPR/ESR) spectrometer.

Active Spectrum introduces the world's smallest Benchtop Electron Spin Resonance (EPR/ESR) spectrometer.


The Benchtop Micro-ESRT includes our patented miniature electron spin resonance spectrometer, operating at 9.6 GHz, with a sweep range of up to 350 Gauss and sub-micromolar sensitivity in aqueous solution.
Also included are a full Windows computer system, integrated touchscreen, Ethernet and multiple USB ports.

Scientific research, education, and industry applications of electron spin resonance are now
extraordinarily cost-effective.

ASI's Benchtop Micro-ESR includes our patented miniature electron spin resonance spectrometer operating at 9.7 GHz with a sweep range of over 300 Gauss and sub-micromolar sensitivity.
Also included are an automatic temperature controller and full Windows 7 computer system with ethernet and multiple USB ports

The spectrometer can be purchased with a number of variable temperature control options.
