| Description |
English: Beckman Ir-1 Spectrophotometer, ca. 1941. On loan from Beckman-Coulter Inc. to the Chemical Heritage Foundation.
Arnold Orville Beckman and Beckman Instruments produced the Beckman IR-1 in 1942 specifically for the Rubber Reserve. By 1945 approximately 75 of the IR-1s had been made—entirely for use by the U.S. synthetic-rubber effort. No one was allowed to publish or discuss anything related to the new machines until the war was over.
