Patent number: 10858697Abstract: A nucleic acid analyzer according to one or more embodiments may include a container setting part that sets a second container, a rotation drive part that rotates the container setting part by applying a driving force to a surface of the container setting part, to supply the extraction liquid injected through the injection port to the storages through the flow path by a centrifugal force. A first temperature adjustment part that adjusts a temperature of the second container provided in the container setting part, such that a nucleic acid amplification reaction occurs in the storages, and a detector that detects a nucleic acid amplification reaction which occurs in the storages with the second container provided in the container setting part interposed between the first temperature adjustment part and the detector in a vertical direction.Type: GrantFiled: October 19, 2018Date of Patent: December 8, 2020Assignee: SYSMEX CorporationInventors: Toshiyuki Ozawa, Masanori Imazu, Hironori Kobayashi, Nobuhiro Kitagawa, Yoshihiko Kitawaki
