Extensive Production Capacity and Latest Technology

Since the start of the operation in 1932, Suita Plant remains as the main factory and the base for research and development, beside that it is expanding every year as our main management center. To lay the foundation for more rapid progress, forming a core for research and development, a multipurpose pilot plant was built in 1985. This was followed by another multipurpose pilot plant in 1989 and then, in 1996,  a specialized plant for pharmaceutical intermediaries.
