Abstract:
A device for producing thin liquid samples with regions of varying thickness for microscopic analysis, wherein said device comprises:(i) a microscope slide having an upper surface for receiving a drop of a liquid sample near its center and a lower surface; (ii) a flexible coverglass having an upper surface and a lower surface wherein a downward force can be applied to said flexible coverglass to cause coverglass bending and enable production of a thin liquid sample; and (iii) spacers, to be positioned between said slide and said flexible coverglass outside of the center of the coverglass, whereby the height of said spacers is selected so that said coverglass, when positioned on said spacers, does not touch the drop of said liquid sample in the absence of said downward force applied to said coverglass and wherein each spacer has a height of from about 10 &mgr;m to about 3000 &mgr;m.
