Benefits of technology
This patent text describes a system and method for filling a plurality of small sample containers with liquids. The containers have a hydrophilic surface and are separated from each other by a hydrophobic surface. The system has a liquid transfer device that can hold the liquid and move it sequentially to the containers by dragging it across the hydrophobic surface. This can be done using a single device or multiple devices. The method can also involve withdrawing residual liquid from the surface of the container and transferring it into other containers. The technical effect of this invention is to provide a faster and more efficient way to fill small sample containers with liquids.
Problems solved by technology
Significant problems associated with current technologies as applied to chemical analysis of vast numbers (potentially on the order of hundreds of thousands or millions per day) of compounds include the problem of handling vast numbers of compounds and reactions in parallel.
It is not practical to apply existing technology in the art to form million-well microtiter plates.

Embodiment Construction
The Through-Hole Array
[0039]In accordance with the present invention, methods are provided for producing different chemical reactions within an array of through-holes. The invention is advantageously employed, for example, in screening operations, where different reaction conditions are advantageously provided among the various through-holes of the array. As an example of the many modalities of use of the invention, different chemical species may be loaded into different through-holes of the array, and concentrations of the various species might also be differentiated among the various through-holes. The invention may thus provide a method for screening compound libraries, for example, to predict the ability of each compound to be absorbed by a patient.
[0040]In accordance with preferred embodiments of the invention, a high-density array of through-holes is provided, as now discussed with reference to FIGS. 1a and 1b. FIG. 1a shows a top view of a platen 10, otherwise referred to her...

Abstract
A method and an array filling system for loading a plurality of disparate sample containers, the sample containers comprising an integral structure. Each receptacle is characterized by a hydrophilic surface, and the receptacles are separated by a hydrophobic surface. The system has a liquid transfer device capable of holding liquid and adapted for motion to cause sequential communication of liquid held in the liquid transfer device with successive receptacles of the array by dragging the liquid across the hydrophobic surface.
