From our incorporation in Horsham, PA. in 1986, United Chemical Technologies, Inc. evolved into a major competitor in the field of silica based solid phase extraction technology. In October 1993, UCT acquired the specialty chemical branch of Huls America (formerly Petrarch). This expansion into silane manufacturing allowed for greater control of the chemical processes involved in producing our high quality bonded phases. Aside from a quality product we also focused on setting ourselves apart with superior technical support of solid phase extraction.
