Abstract
An improved liquid-filming apparatus of the type which utilizes centrifugal action to distribute blood on a specimen-display surface, i.e. on a conventional laboratory slide, and which utilizes a waste-collecting means about the perimeter of the slide display surface. The invention is based on the discovery that the display surface is advantageously related to the surrounding structure in such a way that blood does not disintegrate into minute droplets upon leaving the slide surface and before it can be immobilized in the collecting means. By providing a transitional blood-receiving surface immediately adjacent the supply surface, applicant has avoided the problem of such disintegration.
