Our History

Zeochem, a manufacturer of high-quality molecular sieves, chromatography gels and deuterated compounds, was established more than 200 years ago. With manufacturing facilities in Rüti, Switzerland; Louisville, Ky., USA; Donghai, China; and Zvornik, Bosnia and Herzegovina, we offer customers a wide range of high-performance products and provide coordinated global support.

At Zeochem, we believe our tradition obliges us to maintain the standards set by the Schnorf brothers and to keep growing the company to ensure the future for our customers, our employees and our founders … the Schnorf family.

1818
The Schnorf brothers set up a chemicals factory in Uetikon on Lake Zurich and begin to produce sulfuric acid, iron and copper sulfates. The factory is steadily enlarged over the subsequent decades by reclaiming land from the lake, and the company expands into soda and fertilizer production.
