摘要

The present invention addresses a problem of providing a tissue piece treating method and a tissue piece treating apparatus by which treatment of a tissue piece by each of liquid chemicals can be favorably performed and a running cost can be reduced. In order to address the problem, in a tissue piece treating method in a tissue piece treating apparatus (30) for executing an immersion treatment process by each of the liquid chemicals by supplying the liquid chemicals with different types into a treatment tank (40) in which a basket (42) accommodating the tissue piece is disposed in a predetermined order, a liquid supply/drain cycle in which the liquid chemical in such an amount that the entire basket (42) is exposed in the treatment tank (40) is drained from the treatment tank (40) during the execution of the immersion treatment process by each of the liquid chemicals, and the drained liquid chemical is supplied into the treatment tank (40) so that the entire basket (42) is immersed is repeatedly performed so as to agitate the liquid chemical.
