Your suggestions take form in Thomas Laboratory Specialties. Phrases like "If I had. . .what I need. . .why doesn't somebody. . . " in your letters, in conversations at exhibits, or spoken to the salesman who calls on y o u . . . can trigger the development of a Thomas Specialty. • Relayed to our R&D Department the problem is examined and solutions explored—sketches made, blueprints completed, and a prototype built and tested. Successful prototypes are submitted to you for evaluation of how well they meet the specified requirement. • We do independent research, naturally, which also results in other Thomas Specialties. But here also the product is, in effect, suggested by you. It must fill a need that you have. If a product cannot benefit you, it cannot be successful for us.
