microESR: The Portable Research-Grade Instrument

The microESR is a small, portable research grade instrument. The spectrometer has a mass of only 10 kg and a 30.5 x 30.5 x 30.5 cm3 foot print. It can easily fit in a fume hood or glove box, or be transported to the field. It requires no special installation or regular maintenance.

The microESR is also an ideal teaching tool for undergraduate chemistry labs. This instrument enables classroom demonstrations of both simple topics such as free radicals in everyday life to far less intuitive subjects including electron density, spin-orbit coupling, spin-spin exchange, and forbidden transitions. The Education Package is a very good investment for Chemistry Departments as there are a wide range of labs and subjects that can be addressed with the microESR.

  • Operating Frequency: X-Band
  • Continuous Wave
  • Field Sweep Range: 500 G centered at g=2
  • Spectrum simulation and fitting
  • Easily run samples at liquid nitrogen temperature

microESR – Electron Spin Resonance for the Education Market

Enhance your curriculum with an affordable and easy-to-use microESR instrument. The microESR is ideally suited for teaching and education applications in electron spin resonance (ESR). It offers research-grade results in a compact, portable instrument that features an easy-to-use interface.

  • ESR provides quantitative analysis of paramagnetic species
  • Because it's the only technique to detect species with unpaired electrons, ESR crosses many disciplines, such as biology, chemistry, physics, medical science and material science, opening career options for students

Why Choose the microESR?

  • Focus on the Subject: Intuitive measuring and calibration menus make the instrument accessible to students and teachers alike. With the Bruker microESR it is easier to visualize quantum mechanics
  • Save Space: Small footprint and lightweight, ideal for classrooms or labs with limited benchtop space
  • Get Started Faster: Quick and easy installation.
  • Connect to Your Class: Modern touchscreen interface appeals to students with familiar swipe, pinch, and drop menus

microESR – Electron Spin Resonance for Edible Oil Analysis

Rancidity of edible oil is a major problem in food related industries. It occurs during storage and is caused by oxidation of unsaturated fatty acids, resulting in foul odors and tastes in the final product.

Bruker has developed a benchtop electron spin resonance instrument and software solution specifically for measuring oxidation and shelf life in liquids. The combined system and SOP provide an easy work flow for measuring oxidation profiles in liquid samples. The key metrics such as induction time and end-point free radical concentration are automatically calculated.

Fast, accurate determination of oxidative resistance allows manufacturers to make timely, informed process control decisions.

  • Determine Oxidative resistance in as little as 30 minutes
  • Measures free radicals instead of end products
  • Includes SOP for sample preparation and analysis
  • Compact lightweight with very small footprint
