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.
Through the years, our solid phase product offerings have expanded from columns to well plates, derivatizing reagents, gc liners, flash columns and manifolds. Our diverse product offering along with our dedicated employees and loyal customers have made UCT what it is today. We thank all of you. Now, we focus on the future and another successful 20 years!
Commitment to Quality
As a manufacturer of organosilane chemicals, we are vertically integrated to control both quality and cost. All of our bonded phases are vigorously tested to ensure lot-to-lot reproducibility and performance. Careful attention to particle size distribution, pore diameters and assembly assures consistent column flow. Chemical reproducibility is guaranteed by strict quality control throughout manufacturing. Both our sorbents and chemicals are thoroughly tested to meet or exceed quality specifications. We believe our product reproducibility is unmatched in the industry.
Mission Statement
UCT's mission is to establish and maintain a leadership position in the specialty chemical market for organosilicon products. As a company, we consistently strive to distinguish ourselves from competitors in terms of service, pricing and quality. To accomplish this goal, we continue to invest in the best people, providing them with the finest tools available. Through excellence, UCT is committed to meeting not only the customer's needs of today but also those of tomorrow.
