Abstract: A liquid crystal composition includes a nematic liquid crystal, and a compound of Formula (I) where R is an alkyl, aryl, aralkyl or heteroaryl having 6 to 30 carbon atoms, wherein the compound accounts for 0.3 to 0.6% of the liquid crystal composition. Further, a sensing device includes a substrate, a frame, an alignment film, the liquid crystal composition as described above, and two polarizers. The frame is connected to the substrate and forms an accommodation space having an opening, and the alignment film and the liquid crystal composition are both located inside the accommodation space. One of the polarizers is arranged in correspondence with the opening such that a channel exists between the polarizer and the frame, the other polarizer is located at a lateral side of the substrate, and the polarization directions of the two polarizers intersect with each other.

Abstract: Provided is a measurement container including a container body where a first region, a second region, and an intermediate region are continuously formed as an accommodation space accommodating a sample and an inlet is formed and a rotor which is arranged in the second region and rotated by an effect of magnetic force. 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. 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.
