Abstract
PURPOSE:To prevent the samples, which are repeatedly sampled from an identical container, from being contaminated by forming the openings, which are connected to a plurality of risers, in a rotator contacting with a stationary body and by sequentially connecting them with the openings of the stationary body so that the samples can be accurately sampled several times from an identical container. CONSTITUTION:The contacting surface of a rotor 32, which is rotatable in contact with a staionary body 31, is formed at its circumference of radius r with a plurality of openings 34a, 34b and so on which are connected to plural risers 36a, 36b and so on. The contacting surface of the body 31 is formed at its circumference of radius r with openings 37 and 47. The opening 37 is connected with the openings 40 and 42, which are formed on the side wall or the bottom wall of the body 31, through a pair of conduits 38 and 39 which have communication through the opening 37. A change-over valve 43 has its opening A connected with the opening 40 through the sampling pump 42, its opening D with the opening 41, its opening B connected with a sample bath 44 through a sample pump 45, and its opening C connected with a reaction tube 46. The opening 47 is connected through a conduit 48 with the opening 49 formed in the side wall of the body 31, whereas the opening 49 is connected with a discharge bath 54 through a change-over valve 50 and with a sampling pump 51, a change-over valve 52 and a rinsing pump 53.
