Agar Scientific specialises in offering and producing a wide range of specimens specifically for TEM calibration where quantification or high resolution results are required. We endeavour to maintain the highest possible preparation standards in their production and where possible, we offer specimens that are certified. Agar Scientific calibration specimens for TEM are renown worldwide for their quality and reliability and each one is checked in an electron microscope. Specimens are rejected for exceeding 5% broken grid squares, for excessive dirt, or for inadequate image quality. These criteria govern every Agar calibration specimen. All specimens are prepared on standard 3.05mm copper grids.
