A multiwell instrument includes a vessel having an inside; a plurality of culture plates arranged in the inside of the vessel, each individual one of the plurality of culture plates having an inside in which material to be examined can be stored; and filters disposed inside the respective culture plates to partition the insides of the respective culture plates into at least two wells which are horizontally adjacent.

Multiwell instrument

The present invention relates to a culture vessel which can be broadly applied to culture, regeneration, manufacture, observation and the like of targets such as cells, organs, and microorganisms. In the culture vessel of the present invention, a first vesseland a second vesseleach being a close-bottom, open-top vessel are provided. In the first vesseland the second vessel, a sideways-facing openingand a sideways-facing openingare formed. The openingand the openingcommunicate in a watertight manner when the openingsare connected face to face.
