Measurement container

A measurement container comprising:

• a container body where a first region and a second region located at both ends in a first direction and an intermediate region located between the first region and the second region are continuously formed as an accommodation space accommodating a sample and an inlet through which the sample is introduced into the accommodation space is formed,
• wherein the container body includes:
• a wall portion which defines the accommodation space and at least a portion of which has a light transmitting property;
• and
• a partitioning portion which partitions the intermediate region into one side and the other side in a second direction perpendicular to the first direction,
• wherein the second region is a region where a rotor to be rotated by an effect of magnetic force is arranged,
• wherein the partitioning portion partitions the intermediate region into the one side and the other side so that a communication region which allows the one side and the other side to communicate with each other in the intermediate region remains,
• wherein the container body is configured such that a looping flow path from the first region sequentially through the one side of the intermediate region, the second region, and the other side of the intermediate region and returning to the first region is formed by the rotation of the rotor, and
• wherein the second region is entirely delimited by the wall portion and the intermediate region such that the second region is closed except at the intermediate region.
