We offer contract purification of high-purity research reagents utilizing extraction, refinement, and analysis techniques accumulated over more than half a century.
We have equipped ourselves with various devices to meet the diverse requests for component purification from materials received from our customers. Even for the purification of components that are present in only trace amounts within the materials, our factory's extraction equipment allows for extraction from large quantities of raw materials. By combining precise purification through high-speed liquid chromatography and medium-pressure liquid chromatography, we carry out the purification of trace components. We can accommodate purification on a scale of a few milligrams to grams, tailored to our customers' objectives. ◆ Are you facing any of these issues? ◆ - I want high-purity compounds for analysis that are not commercially available. - I need high-purity plant components in gram quantities for animal experiments. - I want to isolate and purify extremely small amounts of plant components. - I want to perform extraction and purification on a scale that is challenging for my lab. We respond to customer requests with well-equipped facilities, advanced technology, and extensive experience. Please feel free to consult with us.
