It is conceivable that a biological sample is placed in a petri dish and cultured, and microscopic observation is performed in this state. However, in this method, the culture solution evaporates and concentrates, microorganisms in the air are mixed into the culture solution, or gas components in the air dissolve in the culture solution and the components of the culture solution change. As a result, the culture conditions change and become inappropriate.

ら、上記と同様の問題が生じる。In order to cope with such a problem, for example, it is conceivable to prevent oil from coming into contact with the culture solution by spreading oil on the surface of the culture solution. When mixed with the culture solution, the culture solution may be altered, or the surface may be shaken due to the vibration of air, which may hinder the observation of the biological sample. It is also conceivable to provide a lid to form an enclosed space, and culture the biological sample under certain conditions in this enclosed space.However, in this method, water droplets adhere to the inner surface of the lid, and the biological sample is observed. Becomes difficult. Further, it is also conceivable to put a dropping lid on the liquid surface of the culture solution.However, in this method, a gap remains between the petri dish wall and the dropping lid, and the culture solution and air come into contact with this gap. The same problem occurs.

The biological sample culturing container disclosed in Japanese Patent Application Publication No. 69-69139 includes a reaction container containing a culture solution, a light source disposed below the reaction container, and an optical member (object having an end immersed in the culture solution contained in the reaction container). Lens) for observing the biological sample in the reaction vessel with the optical member. However, in this biological sample culture container, since the liquid level of the culture solution is in contact with air, the culture solution is concentrated due to concentration of the culture solution, contamination of the microorganism into the culture solution, and changes in the components of the culture solution. Conditions change and become inappropriate.
