ABSTRACT:
A self-supporting plastic structure having a plurality of through-passages, 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 outlet 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 concurrently to each and all.
