Company Profile


Büchi AG was founded in 1946 by the brothers Jakob Büchi and Hermann Büchi senior. Already three years after the foundation of the company, the two entrepreneurs identified the needs of the market and developed the first “büchiflex” ball and socket system - a new, flexible and interchangeable connection system for glass piping. This unique combination of individual functional components and highly corrosion-resistant borosilicate glass was immediately and universally accepted in the chemical industry.

Pressure reactors (stirred autoclaves) made of metal materials or glass, which were developed later, also quickly became a standard item in companies of the chemical and pharmaceutical industry as well as in research organizations.

The company is still family owned and is headed by Silvio Büchi in the 3rd generation.
