Abstract: A taxis analysis method for performing taxis analysis of nematodes using a container in which a reference point is provided in the container or a culture medium in the container, the taxis analysis method including steps of: imaging a distribution mode of the nematodes in the container after the nematodes and a specimen of a subject are dropped into the container; detecting a position of an object of the reference point corresponding to the reference point included in the image obtained by imaging; determining an attraction region and a avoidance region on the basis of the position; and executing taxis analysis using objects of the nematodes in the determined attraction region and avoidance region.

Abstract: A conveyor line conveys plural containers. A first sampler means moves the containers to a position at which a leaking liquid inspection apparatus is provided. A second sampler moves the containers to a position at which the entering air inspection apparatus is provided. A first stopper interrupts the containers at a position of the first sampler. A second stopper interrupts the vessels at a position of the second sampler. A third stopper is provided on the upstream side of the first and second stopper.
