  • Patent number: 12222289
    Abstract: A reaction processor includes: a reaction processing vessel; a first optical head including a first objective lens OB1 for irradiating a sample with first excitation light and collecting first fluorescence generated from the sample; a second optical head including a second objective lens for irradiating a sample with second excitation light and collecting second fluorescence generated from the sample; and a holding member holding the first optical head and the second optical head. The wavelength range of the first fluorescence and the wavelength range of the second excitation light at least partially overlap with each other. A distance between the optical axis of the first objective lens and the optical axis of the second objective lens satisfies 2·P0+2·P1+4·P2+4·P3<P, P0=L·NA/?(1?NA2), P1=t1·NA/?(n12?NA2), P2=t2·NA/?(1?NA2), and P3=t3·NA/?(n32?NA2).

  • Patent number: 12186756
    Abstract: A reaction processor includes: a vessel installation unit for installing a reaction processing vessel provided with a channel formed in a substrate; a high temperature heater and a medium temperature heater for adjusting the temperature of the channel of the reaction processing vessel; a vessel alignment mechanism for adjusting the position of the reaction processing vessel 10; and a housing that has a housing main unit and a cover portion capable of being opened and closed with respect to the housing main unit and that houses the vessel installation unit, the high temperature heater, the medium temperature heater, and the vessel alignment mechanism. In conjunction with the state of the cover portion being changed from an open state to a closed state, the vessel alignment mechanism aligns the reaction processing vessel such that the reaction processing vessel can be heated by the high temperature heater and the medium temperature heater.

  • Patent number: 11541394
    Abstract: A reaction processor is provided with a reaction processing vessel in which a channel is formed, a liquid feeding system, a temperature control system for providing a high temperature region and a low temperature region to the channel, and a fluorescence detector for detecting the sample passing through a fluorescence detection region of the channel, and a CPU for controlling the liquid feeding system based on a signal that is detected. A target stop position X[L]0(n+1) of the sample in the low temperature region in an (n+1)th cycle is corrected from a target stop position X[L]0(n) of the sample in the low temperature region in the nth cycle based on the result of stopping control on the sample in the nth cycle.
