Liquid from a liquid sample container is flowed in automated analysis apparatus into a filter-equipped inlet end of a probe while the latter is immersed in the liquid, for transport of the sample to automated analysis. The probe is subsequently removed from the container and immersed in the liquid of a wash receptacle. Prior to immersion in another liquid sample, a fluid, other than sample, is flushed through the aforementioned filter in a reverse direction to cleanse it of particulate matter, the flushing being in timed relation to the movements of the probe.
