<P>PROBLEM TO BE SOLVED: To provide an improved apparatus for implementing qualitative and quantitative analyses of a microscopic biological sample, and a method thereof. Ž<P>SOLUTION: The apparatus and method is for separating, immobilizing, and quantifying a biological substance from within a fluid medium. The biological substance is observed by employing a vessel 6 incorporating a chamber, the vessel including a transparent collection wall 5. A magnetic capture structure with a high internal gradient is on the transparent collection wall 5 and magnets 3 produce an externally-applied force for transporting a magnetically responsive material toward this transparent collection wall 5. This magnetic capture structure includes a conductor means supported on the transparent collection wall 5 in order to enable electrical manipulation of the biological substance. This chamber includes one compartment or a plurality of compartments with different heights. The chamber may have a porous wall. The present invention is also useful in conducting a quantitative analysis and sample preparation in conjunction with an automated cell enumeration technique. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
