The CIQTEK EPR200-Plus is a floor-standing EPR spectrometer with enhanced sensitivity for robust continuous wave (CW) EPR measurements. The model can be customized with three different sizes of electromagnets.  An upgraded version, CIQTEK EPR300, is another floor-standing CW EPR spectroscopy with higher sensitivity and optional Q-band extension.   >> EPR200-Plus Accessories: Dual Mode Resonator, High-temperature System, Liquid Nitrogen Variable Temperature With Cryostat, Liquid helium Variable Temperature, Liquid Helium-free Dry Cryogenic System, Time-resolved EPR System, Goniometers, Irradiation system, Flat cell.   Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a powerful analytical method to study the structure, dynamics, and spatial distribution of unpaired electronics in paramagnetic substances. It can provide in-situ and non-destructive information on electron spins, orbitals, and nuclei at the microscopic scale. EPR spectroscopy is particularly useful for studying metal complexes or free radicals so it has important applications in the fields of chemistry, materials, physics, environment, etc.

CIQTEK X-band pulse electron paramagnetic resonance (EPR or ESR) spectroscopy EPR100 supports both continuous-wave EPR and pulse EPR functions, satisfying general CW EPR experiments while performing T1 /T2 / ESEEM (electron-spin echo envelope modulation) / HYSCORE (hyperfine sublevel correlation) and other pulsed EPR tests, which can achieve higher spectral resolution and reveal ultra-fine interactions between electrons and nuclei, thus providing users with more information about the structure of matter.   >> Optionally equipped with a 4-300 K variable temperature device to enable the detection of paramagnetic substances at ultra-low (high) temperatures.>> EPR100 Accessories: Dual Mode Resonator; High-temperature System; Liquid Nitrogen Variable Temperature With Cryostat; Liquid Helium Variable Temperature; Liquid Helium-free Dry Cryogenic System; Time-resolved EPR System; ELDOR System; ENDOR System; Goniometers; Irradiation System; Flat Cell.

W-band (94 GHz) high-frequency electron paramagnetic resonance (EPR or ESR) spectroscopy compatible with both continuous wave and pulsed EPR test functions   EPR-W900 is paired with a slit-type superconducting magnet with a maximum magnetic field of 6 T and can perform variable temperature experiments from 4-300 K.It also has the same software operating platform as the CIQTEK X-band EPR100, providing users with a user-friendly experience.Compared with the traditional X-band EPR technology, high-frequency EPR has many advantages and has important applications in biology, chemistry, and materials.
