In the 1950s, the company name changed to Beckman Instruments, Inc. In the 1950s, Beckman Instruments developed the EASE series of analog computers, [3] [4] two of which were used by NASA in the 1960s for real-time simulation during the development of the Apollo Guidance Computer. [5] In 1954, Beckman Instruments acquired ultracentrifuge maker ...
The DU spectrophotometer or Beckman DU, introduced in 1941, was the first commercially viable scientific instrument for measuring the amount of ultraviolet light absorbed by a substance. This model of spectrophotometer enabled scientists to easily examine and identify a given substance based on its absorption spectrum , the pattern of light ...
Arnold Orville Beckman (April 10, 1900 – May 18, 2004) was an American chemist, inventor, investor, and philanthropist. While a professor at California Institute of Technology, he founded Beckman Instruments based on his 1934 invention of the pH meter, a device for measuring acidity (and alkalinity), later considered to have "revolutionized the study of chemistry and biology".

A standard ultracentrifuge by manufacturer Beckman Coulter. An ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1 000 000 g (approx. 9 800 km/s²). [1] There are two kinds of ultracentrifuges, the preparative and the analytical ultracentrifuge.
Beckman Coulter (now Danaher) has previously manufactured chain termination and capillary electrophoresis-based DNA sequencers under the model name CEQ, including the CEQ 8000. [27] The company now produces the GeXP Genetic Analysis System, which uses dye terminator sequencing. [28]
Invented by Arnold O. Beckman in 1940 [disputed – discuss], the spectrophotometer was created with the aid of his colleagues at his company National Technical Laboratories founded in 1935 which would become Beckman Instrument Company and ultimately Beckman Coulter. This would come as a solution to the previously created spectrophotometers ...
Cary Instruments was founded in 1946 by Howard Cary, George W. Downs and William C. Miller under the name Applied Physics Corporation. Howard Cary previously had been vice president in charge of development for National Technologies Laboratories (later to become Beckman instruments and eventually Beckman Coulter), where he had worked on the development of the DU line of UV/Vis Spectrophotometers.
A Coulter counter [1] [2] is an apparatus for counting and sizing particles suspended in electrolytes. The Coulter counter is the commercial term for the technique known as resistive pulse sensing or electrical zone sensing. The apparatus is based on the Coulter principle named after its inventor, Wallace H. Coulter.
