Micro Essential Laboratory Inc

Micro Essential Laboratory, Inc. was founded by Walter Florin in 1934. As a member of his high school's microscope club, Walter began experimenting with different dyes and chemicals and their application to pH measurement, and noticed a genuine need for a solution to standardized pH testing. With this need in mind, Walter manufactured his first hand-made pH paper while working at his family's pharmacy. The papers created by Walter soon became a profitable business, and he named his small company Micro Essential Laboratory, Inc.
