Novilet is a developer of high-tech laboratory devices based on the Electron Paramagnetic Resonance phenomenon. We focus on the classical low-frequency EPR spectroscopy and we develop a new approach to EPR imaging. We offer the solution dedicated to low-frequency EPR spectroscopy. What makes our device so special is much better sensitivity and the possibility of using lower concentrations of the spin probes (on the contrary to the existing systems). We also solved the problems with the limited sample size, with our spectrometer you can measure in-vivo objects ranging from fish embryos, mice up to a small rabbits. Our second flagship-product is the ERI tomograph, that allows performing dynamic measurements of the microenvironment parameters. Electron Resonance Imaging is a preclinical imaging method that can be applied to a broad range of research in the areas of oncology, neurodegeneration, biology and many more. The ERI TM 600, as the world's only scanner, enables the whole-body 3D imaging of oxygen levels, redox state, oxidative stress, ROS and pH in living organisms.
