Abstract
Apparatus for preparing a smear of a biological fluid substance containing cellular material on a first element having a surface for receiving the smear, utilizing a second element coacting with the first element. The elements are supported so that at least portions thereof are in close proximity to one another at a sample-applying station. A relatively small quantity of such biological liquid sample is introduced between the aforementioned element portions at the sample-applying station for spreading of the sample across at least the central portion of at least one of the aforementioned elements. The sample is spread or smeared on the aforementioned surface of the first element by moving one of the elements relatively to the other. The sample is mixed at least during the drawing of the sample so as to obtain a random distribution of such cellular material and enhance spreading such cellular material in a direction normal to the drawing of the sample.
