A complete range of instruments for petrographic sample preparation, starting with a piece of rock and finishing at 20µm thickness. This exciting product range offers you the latest in technology and functional design to provide high levels of performance in preparation of minerological samples and thin section specimens. For minerological specimens being prepared for reflected light microscope analysis, the preparation procedure is very similar to the preparation of metallographic specimens. Preparing thin sections, on the other hand, requires highly specialized equipment and skills because the specimen is extremely thin, generally around 20µm, for observation with transmitted light microscopes.
