Abstract
Abstract An apparatus for supplying a series of samples to an analyzer, through a tubular element and also for supplying a wash liquid to the tubular element after each of the samples. A radial arm turret having a wash cup upon the end thereof is provided with a drive for rotating the arm through a plurality of stations. A sample carrier is rotatably mounted on the arm and has a plurality of index positions each holding a sample cup with respect to said arm. Gear means between the arm and carrier causes the carrier to rotate a predetermined amount each time the arm rotates 360*, thereby advancing the carrier one index position during each rotation of the turret. The carrier orbits around the rotational axis of the arm so that the carrier is moved toward and away from at least one of the plurality of said stations whereby a series of points on the carrier and one point on the arm can sequentially and alternately occupy the same station during continued rotary movement of said turret. Means are provided for advancing the turret and carrier alternately toward the tubular element so that the sample and wash liquid may be supplied therethrough.
