ABSTRACT:
A filter thimble adapted for use in a float-or-sink process of separating ova from samples of feces contained in standarized transport receptacles has an outside diameter of about 3/4 that of the inside of the receptacle, has a bottom, has an open top, has around its upper side surface a closure operatively fittable to the transport receptacle, and around its lower side surface numerous perforations of dimension only several times larger than the ova. The under surface of the closure is frusto-conical, with smaller end up and fitted liquid-tight to the outside of the thimble, and several of the perforations have their outer openings immediately below the point of fit.
