Physical and chemical appliances have developed rapidly based on the technological advancement in 1955s. High quality glass products for analytical instruments were required in the market. We were established in 1965 as "General physical and chemical glass center" to meet those requirements. Since then, we have been producing and supplying high quality glass/quartz products, and special light sources such as Hollow cathode lamps, Deuterium lamps and physical and chemical appliances etc.

With the integrated production system that we have all production processes in house, we can produce mass-production products, confidential products and prototypes in small quantity with high quality, low cost and short lead-time. We have meetings between each production process quickly to solve the problem. And, with 5S (Seiri: Sorting/ Seiton: Setting/ Seisou: Shining/ Seiketsu: Standardize/ Shitsuke: Sustain), we are trying to eliminate waste and communicate internally to reduce the cost and shorten the lead-time. With the integrated production system, we think we can build up the trust relationship with customers.
