Beckman Model E Analytical Ultracentrifuge Serial Numbers 1 and 1000 |
||||||||||||||||||||
Description |
Dr. Howard Schachman, a Spinco Division technical consultant and professor of biochemistry and molecular biology, displays the Serial No. 1 and Serial No. 1000 of the Model E Ultracentrifuge at an event celebrating the milestone release of the Serial No. 1000 instrument. Beckman Instruments began producing centrifuges after their January 1, 1955 acquisition of industry leader, Specialized Instruments Corporation, or Spinco. With Spinco came the famous Model E Ultracentrifuge, which was developed in 1947 and was used for many important scientific discoveries of the 20th century, like the 1957 CalTech experiment (the Meselson–Stahl experiment) that proved James Watson and Francis Crick’s theory on DNA replication. Centrifuges continue to be produced under the Beckman name as of 2023. Photograph taken December 14, 1965. Published without a copyright notice in Beckman Instruments Feedback newsletter, v9 n2, 1966 (box 44, folder 40). |
