Sample liquid accommodation container, sample liquid stirring device, microparticle sorting kit, and microparticle sorting device

A sample liquid accommodation container comprising:

• a container main body that has a bottomed cylindrical shape with an opening at one end and a bottom surface portion at another end, and accommodates a sample liquid containing microparticles;
• and
• a lid body that has a top surface portion and seals the opening of the container main body,
• wherein the top surface portion of the lid body has a first through hole, and
• an inner surface of the top surface portion of the lid body has an inclined surface inclined upward with the first through hole as a highest point,
• wherein the sample liquid accommodation container is coupled with a microchip that includes a sample liquid inlet into which the sample liquid containing the microparticles is introduced, a main channel through which the introduced sample liquid flows, and a sorting channel where target microparticles are sorted from the sample liquid that has flowed through the main channel;
• a chip insertion unit into which the microchip is inserted;
• a light that irradiates the microparticles flowing through the main channel with light;
• a light detector that detects scattered light and/or fluorescence emitted from the microparticles;
• and
• a controller that controls a traveling direction of the microparticles flowing through the main channel on a basis of data detected by the light detector.
