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 that proved James Watson and Francis Crick’s theory on DNA replication.
The Summary of Model E Operation wall chart insert dates to 1964 and is copyright Danaher Corporation. The remainder of the manual, dating to 1974, is in the public domain in the United States. Intentionally blank pages have been omitted.
