Abstract: 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.

Abstract: 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 vessel 10 and a second vessel 20 each being a close-bottom, open-top vessel are provided. In the first vessel 10 and the second vessel 20, a sideways-facing opening 12 and a sideways-facing opening 22 are formed. The opening 12 and the opening 22 communicate in a watertight manner when the openings 12, 22 are connected face to face.

Abstract: A multiwell instrument capable of extending a use method in a conventional microtiter plate is provided. A multiwell instrument 1 includes a plurality of wells 3, boundary portions 4 respectively provided between the respective wells and adjacent wells, and a filter 6 provided in at least one boundary portion of the boundary portions 4.

Abstract: A packaging container has an improved degree of freedom in the shapes of a container body and a cap, and prevents required turning force from being excessively large. The packaging container includes a container body having an upward-facing mouth, and a cap for closing the mouth. The container body has a plurality of axial drive ribs and a circumferential locking groove formed on an outer perimeter of the mouth. The cap has protruding rib portions on an inner surface side and locking claws to elastically lock into the locking groove, extended down from a top surface thereof.
