When a stirring deviceperforms processing of stirring a mixed solution in a test tube S, a holding mechanismand a movement mechanismare operated so that the test tube S is moved to a position of B. Then, in the test tube S, the cells attached to the inner surface of the test tube S and the liquid are separated. Further, the cells attached to the inner surface of the test tube S are detected by a color sensor. Therefore, it is possible to reduce the work for determining the end of the stirring processing by the user. As a result, the workability of the user when using the stirring devicecan be improved.

A cap attaching/detaching deviceis a device for attaching or detaching a capin which a screw portion is formed to or from a test tubeby rotating the cap. A cap grip portiongrips the cap. A rotation mechanismattaches or detaches the capto or from the test tubeby rotating the capby rotating the cap grip portion. The rotation mechanismhas an axial portion, and a nut portion. The axial portionhas an outer peripheral surface on which a screw threadis formed. The nut portionhas an inner peripheral surface on which a screw grooveto be screwed into the screw threadof the axial portionis formed, and rotatably holds the axial portionin a fixed state. A pitch of the screw threadis the same as a pitch of the screw portion formed in the cap

A method of cultivating algal cells of an algae belonging to a class selected from Chlorophyceae, Euglenophyceae, Bacillariophyceae and Haptophyceae includes: irradiating the algal cells with an artificial light having a ratio of (i) photon flux density in a wavelength range of 520-630 nm to (ii) photosynthetic photon flux density, that is 65% or more; and measuring a cell size of the algal cells. Irradiation and non-irradiation of the algal cells with the artificial light are switched, or the photon flux density in the wavelength range of 520-630 nm is changed, according to the measured cell size.

A solid-liquid boundary detection device 20 is a device for detecting a boundary 141 between a solid and a liquid in a test tube 14, and includes a surface illumination 21, an imaging unit 22, and a boundary detection processor 31. The surface illumination 21 illuminates the test tube 14 from outside. The imaging unit 22 is arranged on an opposite side of the test tube 14 from the surface illumination 21, and captures an image including the boundary 141. The boundary detection processor 31 detects the boundary 141 from the image captured by the imaging unit 22.

Sampling device

A method of cultivating algal cells of an algae belonging to a class selected from Chlorophyceae, Euglenophyceae, Bacillariophyceae and Haptophyceae includes: irradiating the algal cells with an artificial light having a ratio of (i) photon flux density in a wavelength range of 520-630 nm to (ii) photosynthetic photon flux density, that is 65% or more; and measuring a condition of the algal cells and/or a condition of an algal cell culture provided by cultivating the algal cells. Irradiation and non-irradiation of the algal cells with the artificial light are switched, or the photon flux density in the wavelength range of 520-630 nm is changed, according to the measured condition of the algal cells and/or the measured condition of the algal cell culture.
