Abstract:
A method for producing thin samples of liquids for microscopic analysis, said method comprising:a) providing an apparatus comprising (i) a base portion; (ii) a means for containing said thin liquid samples carried by said base portion, having an interior and exterior, and outside walls, and (iii) a lid portion; wherein the base portion, said means and the lid portion form a cuvette, wherein the cuvette has a sample entrance, wherein said cuvette has a plurality of separating walls which separate the interior of said cuvette into a plurality of successive compartments, and wherein each of said separating walls comprises a first type of through-channel sized so as to allow sample particles and sample liquid to flow through said first through-channel, and a second type of through-channel sized so narrow in one direction as to allow only sample liquid to flow through said second through-channel, wherein the first type of through-channel is sized in a way that a significant percentage of sample particles arriving at a separation wall can pass through; b) depositing a liquid sample into the sample entrance; c) allowing the liquid sample to flow from the sample entrance into the cuvette; d) further allowing the liquid sample to flow into each compartment created by the plurality of separating walls and flow through each separating wall until the sample flows through a last separating wall to a last compartment; and e) obtaining the thin liquid sample in the last compartment.
