A group of eleven men, standing and crouching indoors in front of various pieces of unidentified scientific equipment.

The Beckman Instruments IR spectrophotometers began as a request from the Office of Rubber Reserve to Arnold O. Beckman in 1942, asking for an infrared spectrophotometer that they could use to create rubber. Under this…

Liquid scintillation counters measure the radioactivity of a sample by mixing the sample with a solvent containing a scintillator, which will emit photons in the presence of radioactive materials. The counter measures…

This system's connection to Beckman Instruments is not clear. It may be that one of all of the components were manufactured by Beckman.

Arnold Beckman invented his first pH meter in 1934 at the request of a chemist from the California citrus industry, who needed an accurate way to measure the acidity of his product. The resulting “acidimeter” with its…

First marketed in 1960, the Beckman/Spinco Model 120 Amino Acid Analyzer used the Spackman-Stein-Moore technique of amino acid chromatography.

This exhibit was ultimately installed in the Fullerton, California headquarters of Beckman Coulter in 2009. The men in this image may be employees of Activate (formerly DisplayWorks), the exhibit and marketing…

These men and this instrument are from the Special Products Division of Beckman Instruments.

It is unclear from this photograph whether this is a Model 150 or 160.

From the Beckman Historical Collection, this unidentified photograph may have been taken at a company event at Beckman Instruments, Inc.

First marketed in 1960, the Beckman/Spinco Model 120 Amino Acid Analyzer allowed users to quickly perform amino acid chromatography. This unidentified instrument is likely from the same product line as the 120.
