ABSTRACT:
A specimen stirring device has a stirring impeller on a rotating shaft enclosed in a pipe having one or more side holes in a central portion thereof and a nozzle portion at its end and by rotation of the stirring impeller can create a circulating flow of specimen liquid flowing out of the pipe through the nozzle portion, upward along the outside of the pipe and back into the pipe through the side holes and thereby efficiently stir a specimen liquid in a specimen container even if the specimen container is long and slender or has a tapered bottom and without there being a possibility of the stirring impeller and the specimen container making contact with and damaging each other. A specimen sampling apparatus including this specimen stirring device is also disclosed.
