Bio-Rad Laboratories, Inc.
A maker of instruments, reagents, and consumables for life-science research and clinical diagnostics, Bio-Rad's products help labs separate and analyze biological materials and run diagnostic tests. Founded in 1952 by UC Berkeley graduates David and Alice Schwartz, the company began in a Quonset hut in Berkeley, California. Its name is a portmanteau of its first product lines: biochemicals and radiochemicals.
