"The Ideal 'Everywhere' Spectrometer"Extend your laboratory’s capabilities with the next-generation benchtop EPR / ESR spectrometer from Bruker. The versatile ESR5000 is an easy to use research grade instrument with sensitivity and reliability for demanding applications.Size matters when lab space is scarce but so does ease of use and performance. The ESR5000 addresses this as an easy to use, compact, and powerful research grade instrument. Focus on your research and not on the instrument with ESRStudio, the most modern and dynamic software for ESR / EPR measurements. The simple and intuitive user interface doesn’t require you to be an expert in spectroscopy to get accurate results. Need to take Liquid Helium (He) or Nitrogen (N2) measurements? The ESR5000 with optional accessories (He Cryostat / Temperature Controller) allows you to meet these requirements. Looking for Quality Assurance? The ESR5000 also addresses standards such as EN 1786, 1787, 13708 related to irradiated food testing.
EPR/ESR spectroscopy has wide field of applications from research & development to quality control in branches like: > Life SciencesNitric oxide measurement, reactive oxygen species, oxidative stress, radical generating systems, photo dynamic therapy > Bioinorganic Chemistry Bioinorganic transition metal compounds, fenton chemistry, effect of heavy metal ions on living tissue > Environmental Toxicology Generation of radicals by particles > Petrochemistry Living polymers, nitroxide quantification, radicals in varnish, UV stability of scratch resistant varnish> Biophysical Features Oxymetry, membrane fluidity, pH in micro-environment, viscosity and phase partition > Separation of RadicalsEPR/HPLC coupling > Food Chemistry and PharmacyAntioxidative features of foodstuff, radicals in foodstuff, radiation induced radicals > CosmeticsRadical protection factor, protection features of UV-filters in créme, shampoo, etc> Alanine DosimetryAlanine dosimetry (tablets, thin films)
"The Most Sensitive TLD/OSL Reader"Thermal Stimulation
Ceramic heating element allows highly reliable and more consistent measurements. The heating element is cooled by continuous flow of nitrogen or compressed air.
Thermoluminescence (TL), preheat (PH) including elevated temperature luminescence measurements (OSL, RL, etc.) as well as elevated temperature irradiation (at ionizing irradiation and “solar-light” position) are possible during any part of a heating/cooling cycle, which is almost freely programmable including non-linear heating/cooling functions.Optical Stimulation (OSL)All Lexsyg Smart and Lexsyg Research TL/OSL readers can be equipped with an interchangeable OSL unit containing up to three stimulation wavelengths. These are provided by high power stimulation elements optionally as LEDs or laser diodes. The integration of photo diodes provides the feedback for power control of each individual element, guaranteeing a stable stimulation source, independent of element aging. Looking for Quality Assurance? The Lexsyg Smart addresses standards EN 1788 and EN 13751:2009 related to irradiated food testing.

The Bruker microESR is an affordable research grade spectrometer designed for portability with a 30.5 x 30.5 x 30.5 cm3 footprint and mass of just 10 kg (22 lbs). This spectrometer is one of the more compact, lightweight, and lower cost ESR / EPR spectrometers on the market. The compact size allows you to easily work in a fume hood, glove box, or transport it to the field with ease. In addition, no special installation or regular maintenance is required! If you are a university professor, use this as a tool to take your students on a journey with demonstrations of both simple (everyday free radicals) and complex (electron density, spin-orbit coupling, etc) experiments. The Education Package is a great investment into an instrument that will yield results for years to come. Explore the unknown with the microESR portable benchtop ESR / EPR Spectrometer.
