A History of Innovation

In 1919 a young chemist, Frank LaMotte, decided to focus his expertise in the area of pH analysis on specific applications of chemical control. Within a few years, LaMotte’s small laboratory in Baltimore, Maryland was manufacturing specialized pH indicators and other analytical reagents for world-wide distribution. The applications section of LaMotte’s first major catalog, published in 1930, anticipated many of the areas in which accurate chemical control is indispensable today – boiler water, swimming pools, drinking water, and more.

Today LaMotte Company manufactures analytical reagents, laboratory apparatus, electronic instrumentation, and complete portable test kits for chemical analysis in hundreds of applications.
