Abstract
A method for analyzing solid material in a liquid sample comprises the steps of: distributing the sample equally by passage through a number of discrete wells adapted to retain the solid material, the concentration of solid material being such that it is absent in at least one well; and analyzing the wells for the presence of retained solid material. A device adapted for use in a method for analyzing solid material in a liquid sample comprises the combination of: a container for the sample; a unit comprising a number of discrete wells adapted to retain the solid material and allow the passage of liquid under the application of reduced pressure; structure for drawing liquid from the container and through the wells under reduced pressure; and a manifold or other element that provides uniform distribution of the sample passing from the container into the wells.
