ABSTRACT:
A continuous sampler having a predetermined number of sample containers in which a sample from a liquid flow is deposited at predetermined intervals of time. Samples are deposited in sample containers in a sampling position and the sample containers are stepped once each interval of time through a path of travel until they assume a cleaning position adjacent to the sampling position. A sample removal probe and a wash probe is lowered through an access opening in the sample container in the cleaning position and a source of washing solution is coupled to the wash probe and means for removing the contents of the sample container is coupled to the sample removal probe. Means for controlling the position of the wash and sample removal probes in a position inside the sample container in the cleaning position and in a position remote therefrom, as well as controlling the means for removing samples therefrom and the means coupling a wash solution thereto is provided. The wash probe is purged by introduction of pressurized air prior to removing the wash probe from the interior of the sample container in the cleaning position and the means for removing the contents of the sample container in the sample cleaning position continues to function until the sample container is advanced from the cleaning position to the sampling position. Residual wash solution and removed liquid in the wash probe and sample removal probes respectively is thereby precluded from collecting in the sample container in the cleaning position.
