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".

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 ...
Schematic diagram of 3-part analyzer. A 3-part differential cell counter uses Coulter's principle to find the size and volume of the cell. The sample is lysed and dissolved into an electrolyte solution in a container, which also holds a smaller container.
The Beckman Institute for Advanced Science and Technology is a unit of the University of Illinois Urbana-Champaign dedicated to interdisciplinary research. A gift from scientist, businessman, and philanthropist Arnold O. Beckman (1900–2004) and his wife Mabel (1900–1989) [1] [2] led to the building of the Institute which opened in 1989.
A Beckmann thermometer; (R) Reservoir; (B) Bend. A Beckmann thermometer is a device used to measure small differences of temperature, but not absolute temperature values. It was invented by Ernst Otto Beckmann (1853 – 1923), a German chemist, for his measurements of colligative properties in 1905. [1]

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.
