Abstract:
Cell counters and methods of their use are disclosed herein. The cell counters comprise a sample mounting system that includes a base comprising a mounted lower sample surface and a cover comprising a mounted upper sample surface; a bright-field light source incorporated in the cover; an objective lens mounted below the sample mounting system; optionally, a fluorescence excitation source in optical communication with the sample mounting system; and an imaging system in optical communication with the bright-field light source and the objective lens. The mounted sample surfaces are configured for repeated use, such that disposable sample cartridges are not needed.

Claim (Index 22):
A device for measuring cells or particles in a suspension, comprising:\n (i) a bright-field light source; (ii) an imaging system; and (iii) a sample mounting system comprising upper and lower sample surfaces configured for direct receipt of a sample comprising a suspension of cells or particles, the system comprising:\n (A) a base having a base top side, a base bottom side, and an objective lens cavity located on the base so as to align with and receive one or more objective lenses of the imaging system; \n (B) a hinge fixed to the base; \n (C) a movable arm fixed to the hinge, said movable arm having a movable arm top side, a movable arm bottom side, and a bright-field light source cavity located on a portion of the movable arm distal to the hinge and configured to receive the bright-field light source; \n (D) the lower sample surface mounted to the base top side in a position configured to receive bright-field light from the bright-field light source when the movable arm is in a closed position; and \n (E) the upper sample surface mounted to the movable arm bottom side of the movable arm in a position configured to receive bright-field light from the bright field light source; \n wherein a distance between the lower sample surface and the upper sample surface when the moveable arm is in the closed position is adjustable to accommodate variable volumes of samples deposited between the upper and lower sample surfaces; \n wherein the system is re-usable by moving the movable arm to an open position and cleaning the sample surfaces.
