Abstract: Provided are a liquid agent container formed of a multilayer film using polybutylene terephthalate in an outer layer, in which it is controlled or prevented that a component derived from the polybutylene terephthalate is permeates the multilayer film and is eluted into a content liquid, and a multilayer film for forming such a liquid agent container. A multilayer film includes at least a layer (1) including polybutylene terephthalate, a layer (2) including a cyclic olefin-based polymer, a flexible layer (3) including an ethylene-based resin, and a layer (4) including a polyolefin, which are laminated, wherein the layer (1), the layer (2), and the layer (4) forming one surface of the multilayer film are laminated in this order, and a liquid agent container is formed of the multilayer film so that the layer (4) is formed as the innermost layer.

Abstract: Provided are a novel printed base material and the like. In particular, provided is a printed base material comprising a printed area on a base material, wherein the printed area comprises a differently colored printed area having different colors separated by a clearance.

Abstract: A cell culture analyzer comprises a stirring member and an air discharge and intake unit. The stirring member is used in a state of being immersed in a medium, and has a liquid discharge and intake port for discharging or drawing in the medium, and an air discharge and intake port for discharging or drawing in air in order to discharge or draw in the medium from the liquid discharge and intake port. The air discharge and intake unit is linked to the air discharge and intake port of the stirring member, and discharges or draws in the air discharged or drawn in from the air discharge and intake port.

Abstract: A sensor performs measurement of a culture medium and is used in a state of being immersed in a medium placed in a well, the sensor comprising a main body having a first surface and a second surface that is on the opposite side from the first surface; an electrode unit that is provided on the first surface in the main body and to which a specific voltage is applied in the course of performing measurement in a state of being immersed in the medium; and a liquid holding portion that is provided around the electrode unit on the first surface, and that is disposed near the inner wall surface of the well and holds the medium up to above the electrode unit, in between the inner wall surfaces.

Abstract: A sensor unit (9) comprises a substrate (13) having a sensor (16), wiring (19) connected to the sensor (16), connection portions (20a, 20b) connected to the sensor (16) via the wiring (19), and a bent portion (17) where the sensor (16) is bent downward. The sensor (16) is formed so as to be cut out from the substrate (13) in a state in which the bent portion (17) remains on the substrate (13).
