Hematology analyzers are used to conduct a complete blood count (CBC), which is usually the first test requested by physicians to determine a patient's general health status. [5] A complete blood count includes red blood cell (RBC), white blood cell (WBC), hemoglobin , and platelet counts, as well as hematocrit levels.
The company was founded by Caltech professor Arnold O. Beckman in 1935 as National Technical Laboratories to commercialize a pH meter that he had invented.. In the 1940s, Beckman changed the name to Arnold O. Beckman, Inc. to sell oxygen analyzers, the Helipot precision potentiometer, and spectrophotometers.
Roche Cobas 6000 Roche Cobas u 411 Beckman Chemistry analysers: Access (left); Synchron (right). Racks: for putting samples, quality controls or calibrations. Cobas 6000 These tubes are put in the racks for testing. Photometry is the most common method for testing the amount of a specific analyte in a sample. In this technique, the sample ...
The Coulter counter was initially designed for counting red blood cells, but with later modifications it proved effective for counting white blood cells. [60] Coulter counters were widely adopted by medical laboratories. [211] The first analyzer able to produce multiple cell counts simultaneously was the Technicon SMA 4A−7A, released in 1965 ...
The electrode of a Coulter counter. A Coulter counter is an appliance that can count cells as well as measure their volume. It is based on the fact that cells show great electrical resistance; in other words, they conduct almost no electricity. In a Coulter counter the cells, swimming in a solution that conducts electricity, are sucked one by ...

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".
