The Astra 4 and 8 analyzers used multiple channels to perform continuous flow and discrete analyses of electrolytes and "routine chemistries." The 8 was controlled by a microprocessor with 52K bytes of memory.

Beckman's foray into ultraviolet spectroscopy began in 1940, when the company (then called National Technical Laboratories) produced the DU prototype. The double-beam Model 25 was introduced in the early 1970s.

The Astra line of analyzers used multiple channels to perform continuous flow and discrete analyses of electrolytes and "routine chemistries."

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 instrument kicked off…

Developed from a Linus Pauling design during WWII, the technology behind Beckman Instruments’ oxygen analyzers ended up doing such diverse jobs as monitoring astronauts’ respiration, maintaining packaged food safety,…

Although the instrument in the photograph has been labeled DEA 422, it appears to be a member of the DSA series of Discrete Sample Analyzers.

Beckman's Microtox Acute Water Toxicity Monitor debuted in 1979.

Beckman's Microtox Acute Water Toxicity Monitor debuted in 1979.

This device may have been used as an attachment to a gas chromatograph.

This recorder was used with Beckman's Microtox Acute Water Toxicity Monitor.

TOXSYS software facilitates the chemical analysis of body tissues.

Medical books and a microscope sit on a desk beside a Beckman TOXSYS terminal. The TOXSYS software facilitates the chemical analysis of body tissues.

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

The Model 915 converted samples to carbon dioxide and used a non-dispersive infrared analyzer to determine the total carbon and inorganic carbon. Organic carbon was determined as the difference between those values.

The MV 8000 Process Control System is a multivariable control unit first released in 1979 and used in industrial settings.

The Ignition System Tester was also known as an Engine Scope Tester.
