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.
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 ...
