Which year marks the introduction of the first commercial centrifugal analyzer?

• A. 1970
• B. 1957
• C. 1967
• D. 1976

Answer: (A)

The main point is the history of automated clinical chemistry instruments and when centrifugal technology first became commercially available. A centrifugal analyzer uses spinning motion to move liquids and perform measurements in fixed cuvettes, enabling rapid, automated testing in the lab. The first commercial centrifugal analyzer is dated to around 1970. This marks the moment labs could purchase a purpose-built instrument that used centrifugal force as its operating principle, rather than relying solely on the earlier flow-based approaches. Earlier milestones include the 1957 introduction of the first commercial continuous-flow autoanalyzer, which represents a different technology path and predates centrifugal devices. Mid- to late-1960s efforts contributed prototypes and related concepts, but the inaugural commercial centrifugal instrument is typically cited as 1970. The 1976 option reflects later generations and improvements rather than the initial introduction.
