Mitorika Co., Ltd

At Mitorika Co, Ltd, we specialize in the manufacturing and sales of precision glass products—quartz glass, borosilicate glass, and sapphire—for a wide range of industries, including scientific research, semiconductors, biotechnology, aerospace, environment, energy, automotive, and food. We also provide light sources for analytical instruments such as spectrophotometers, atomic absorption spectrometers, high-performance liquid chromatography (HPLC), and film thickness measurement systems for semiconductors. Our product lineup includes deuterium (D2) lamps, hollow cathode lamps, xenon flash lamps, helium lamps, ozone generators, and hot cathode ionization vacuum gauges. Mitorika delivers custom-made quartz, Pyrex, and Tempax glass components, from prototypes and small-lot production to mass production. We also offer repair services for scientific and laboratory glassware. In addition, we handle vacuum sealing and gas replacement sealing for alkali metals such as rubidium (Rb) and cesium (Cs) used in optically pumped atomic magnetometers (OPAM) for atomic clocks and ultra-low-field MRI, as well as for glass ampoules and other applications. Our team of highly skilled glass artisans—specializing in polishing, flame working, cutting, lathe processing, and deposition—together with expert lamp craftsmen, dedicate their craftsmanship and precision to each and every product. We proudly serve clients not only across Japan but also worldwide. Please feel free to contact us for inquiries.
