ABSTRACT:
A method and device for collecting and evaluating an embryo contained in a fluid medium. The fluid containing the embryo is discharged into a receptacle and sequentially drained and filtered until the remaining fluid containing the embryo is located in the proximity of a transparent flat bottom wall. The receptacle includes sloped side walls to keep the embryo from sticking to the side walls. Vertically spaced filter meshes are provided on the side walls to allow sequential filtering and draining. The fluid is discharged through a tube directed away from the filter meshes to prevent the embryo from being lodged in the filter mesh. A light projection chamber can be provided to concentrate light on the flat bottom wall.
