Abstract: According to one or more aspects, a specimen processing method may use a cartridge comprising a chamber configured to store a liquid. The method may include: storing a specimen and a dispersion medium in the chamber of the cartridge; and rotating the cartridge about a rotational shaft to agitate the specimen and the dispersion medium in the chamber, to thereby form an emulsion in which a dispersoid containing the specimen is dispersed in the dispersion medium.

Abstract: A specimen measurement apparatus may include: an aspirator via which a specimen is aspirated. A flow path may be connected to the aspirator. A first pump may be connected to the flow path. A second pump may be connected to the flow path. A controller may select and cause either the first pump or the second pump to aspirate the specimen via the aspirator.

Abstract: A flow cytometer, in which detection of light generated from a particle is less likely to be affected by change in a flow velocity of a liquid flowing in a flow cell, is provided. The flow cytometer includes: a flow cell (10) in which a liquid flows; a liquid sending unit (40) configured to send the liquid into the flow cell (10); a controller (300) configured to obtain information related to a flow velocity of the liquid flowing in the flow cell (10); a light source (121) configured to irradiate the liquid flowing in the flow cell (10) with light; and a detector (162) configured to detect light generated from a particle in the liquid irradiated with light. The controller (300) changes a liquid sending condition for the liquid sending unit (40), based on the obtained information related to the flow velocity.
