ABSTRACT:
Apparatus for storing and mixing blood samples comprises separate storage and mixing discs for storing and mixing blood samples in containers. The discs are driven independently and are provided with complementary grooves. A loading device loads the containers into the storage disc where they are transported to a transfer device. The transfer device successively transfers the containers into an oppositely situated groove of the mixing disc. The mixing disc mixes the blood samples via rotation thereof, after which the containers are transferred to a blood removal device which rotates each container with its blood sample about the lengthwise axis thereof so that a bar code reading device can read a bar code applied to the container. Blood is then withdrawn from the container and delivered to a blood analyzer, after which the container is ejected from the mixing disc by rotation of the mixing disc.
