Redrawn capillary imaging reservoir

A tool for transferring liquid from a first multiwell plate having a predetermined density of wells per unit area to a second multiwell plate having a proportionally greater density of wells per unit area comprising:

• a plurality of channels collectively forming a matrix having a top and bottom of predetermined cross sectional area, each channel having an open input face of predetermined cross sectional area and an open output face of predetermined cross sectional area;
• at least one of said plurality of channels containing the liquid and being configured to retain the liquid by capillary force;
• said matrix being shaped such that said cross sectional area of said matrix bottom is smaller than said cross sectional area of said matrix top;
• said input faces of said channels having substantially identical spacing to the spacing of said wells of said first multiwell plate such that said wells align with said input faces;
• and
• said output faces of said channels having substantially identical spacing as that of said wells of said second multiwell plate such that a portion of said wells from said second multiwell plate align with said output faces.

A device for depositing an array onto a substrate comprising:

• a plurality of channels collectively forming a matrix having a top and bottom, said bottom providing a nonwetting surface, each channel having walls defining an open inlet and an open outlet of smaller cross sectional area than said open inlet;
• at least one of said plurality of channels containing a liquid and including an interior wall having a wetting surface;
• and
• the cross sectional area of any one channel as a proportion of the cross sectional area of said matrix being substantially identical on said top and said bottom.

• at least one of said plurality of channels containing a liquid;
• said cross sectional,area of said inlet being greater than said cross sectional area of said outlet;
• and
• the cross sectional area of any one channel as a proportion of the cross sectional area of said matrix being substantially identical on said top and said bottom.
