ABSTRACT OF THE DISCLOSURE In a preferred embodiment, there is provided a self-support- ing plastic structure having a plurality of through passages positioned substantially uprightly formed by the structure there- of and being of elongated passage shapes, each passage being of cross-sectional shape and area such that walls thereof provide a large amount of surface area relative to a substantially small amount of space cross-sectional area, each through passage having an upper funnel portion for receiving liquid, and a small outlet aperture of a smallness sufficient to effect a retention of liquid drop (s) within space of the through-passage by capillary action in the absence of additionally added fluid which by weight thereof forces liquid from the oulet aperture, and a separate washer structure seatable above the plastic structure and having a main liquid-containable vessel defined with a plurality of open outlets in the base thereof aligned for feeding contained liquid into separate ones of the through-passages simultaneously for the concurrent washing of each and all and/or for concurrent adding of further reagent or the like simultaneously concurrent to each and all. Normal procedures requires that the plastic structure be coated within its plurality of passages with particular antigen(s) per through-passage, to be tested, or with antibody (ies) as the case may be, and thereafter, utilizing the washer, washing water (or the like) be added, followed by adding the next material to all, etc., in each addition of liquid through the washer the total plurality being either washed or treated, with excess and washed material being merely simultaneously drained through the small outlet aperture for each through-passage, supported with the outlet apertures suspended above a supporting surface to avoid contami- nation by contact with the surface.
