1. A system for analyzing cells from blood or bone marrow comprising:
- a. an applicator for dispensing a fluid comprising the bone marrow or blood, said applicator comprising an applicator controller and a tip for dispensing the fluid and the cells onto a slide;
b. a light receiving device containing a lens for capturing an image of the cells on the slide;
c. a computer containing a microprocessor and software stored on computer readable media for causing the computer to perform the steps of;
i. instructing the applicator controller to position the tip a certain height above the slide;
said position having an X, Y, and Z directional component;
ii. instructing the applicator controller to move the applicator tip at a certain velocity across the slide;
said velocity having a directional component and a speed component;
iii. instructing the applicator to direct the diluted fluid out of the tip at a certain velocity;
iv. causing the tip to apply a first flow of cells across the slide such that the tip'"'"'s position has a constant Z component;
said flow comprising a monolayer of cells and a flow width;
v. directing the applicator controller to change the position of the tip by a certain distance; and
vi. causing the tip to apply a second flow of cells across the slide such that the tip'"'"'s position has a constant Z component, and the second flow of cells settles into a position near the first flow of cells.
