About Teaco Laboratories

In 1975, Mr. Thomas Arnold formed a partnership with three other individuals to create Bio-Quality Laboratory. The purpose was to provide testing services to the dairy, frozen dessert and water industries. It was also established to provide competition in a market where one other laboratory provided the same services. Over a ten year period, the other 3 partners developed other interests. In 1985, Mr. Arnold acquired total control of the laboratory and changed the name to Teaco Laboratories, Inc. Today, we still provide testing services for the dairy, frozen dessert and municipal/residential water and swimming pools. We expand into areas that complement our current competencies. The laboratory is certified by both the Pennsylvania Deparment of Agriculture and the Pennsylvania Department of Environmental Protection. All analyses are performed according to the Seventh Edition of Standard Methods for the Examination of Dairy Products and the Twelfth Edition of Standard Methods for the examination of Water and Wastewater.
