The first commercial centrifugal analyzer was introduced in which year?

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

Answer: (A)

Timing of the first commercial centrifugal analyzer release marks a milestone in automation for clinical chemistry. Centrifugal analyzers use rotating rotors to move samples through reagents and cuvettes, enabling rapid, multi‑assay testing with reduced manual handling. While prototypes and research models existed earlier, the first model that labs could purchase—bringing true automation to routine testing—appeared circa 1970. That makes this date the best choice among the options, because the earlier years mostly reflect development or non-commercial devices, and the later year represents subsequent improvements rather than the initial market entry. This helps you see how automation progressed from concept to a product labs could buy.
