摘要： A diluter for use in a kinetic analysis apparatus for picking up a serum sample from a container and diluting it into a reaction cup in which a diluter probe mounted for vertical translation and horizontal rotational motion is coupled to a sample pump with the sample pump coupled to a diluter pump and wherein the probe is caused to be lowered into a container of serum sample after which said sample pump draws into said probe a measured amount of sample whereupon said probe is raised, rotated and then lowered to a position over a reaction cup; the diluter pump is then operated to discharge said sample along with a measured amount of diluent. Vertical translation and horizontal rotation of the probe is achieved by means of a pair of coaxially disposed cylindrical cam members one of which is fixed and the other rotatable about the common axis. Cut-out portions in the cam members define respective coacting camming surfaces which are engaged by and control the vertical position of a radial probe-supporting arm as it rotates about the common axis between respective limit positions where the probe overlies the sample container and reaction cup.
