Company information
For total support of precision cutting machines, sample polishing machines, and resin embedding machines necessary for organizational observation, please consult Hartzok Japan.
Hartzok Japan has been a specialized company in preprocessing equipment for about 30 years. The preprocessing equipment we handle refers to devices that create samples in optimal conditions for analytical instruments. In recent years, the performance of analytical instruments has improved, allowing for more precise analyses. However, as the accuracy of analysis increases, the results can vary significantly based on the preprocessing steps. For example, even if there is a high-spec microscope, poor preprocessing due to contamination, loss, or uneven polishing can lead to low analytical accuracy. Conversely, even a low-spec microscope can yield high-accuracy results if the polishing is done well. Preprocessing equipment is often postponed in capital investments, but the results of the preprocessing steps become more critical as higher analytical accuracy is sought. Furthermore, this preprocessing process is largely analog and relies heavily on empirical knowledge. Hartzok Japan will contribute to improving our customers' quality with the know-how we have cultivated over many years in the preprocessing field.

Business Activities
<Pre-treatment for Analytical Samples> We import and sell equipment from the world's top manufacturer "HERZOG." We handle pre-treatment devices for fluorescent X-ray (XRF) and optical emission spectrometry (OES) analysis, such as crushers, cutters, glass bead samplers, polishers, and cutting machines, utilizing technology and ideas that boast an overwhelming global market share, and we are also working on their full automation. <Pre-treatment for Organizational Observation> We import and sell equipment and consumables used for microscopic tissue observation. We handle devices for sample preparation such as cutting machines, embedding machines, and polishers, along with associated cutting wheels, embedding resins, polishing papers, polishing cloths, and diamond abrasives. <Consumables for Analytical Instruments> We offer consumables for gas analysis instruments, ICP instruments, standard materials, calibration samples, etc., at low prices. We deliver carefully selected equipment, parts, and consumables from around the world at low prices through our unique network. Furthermore, we are developing products that are not available in the market, including domestic brand items, to shape the voices of our customers into reality.
