Abstract:
Rapid and uniform temperature changes in the wells of a microplate or any thin-walled plate that contains an array of reaction wells or sample receptacles are achieved by the use of heating and cooling elements with a vapor chamber interposed between such elements and the microplate. The upper surface of the vapor chamber and the underside of the sample plate in certain embodiments are complementary in shape, i.e., they have identical but oppositely directed contours in the areas around each of the sample receptacles, to provide continuous surface contact along the surface of each receptacle. In other embodiments, an intermediary plate is placed between the vapor chamber and the well plate, with the top surface of the intermediary plate being complementary in shape to the underside of the well plate.

Abstract:
A method for efficiently manufacturing and fabricating microfluidic chips, where a base mold is formed to have positive-relief features used to cast an intermediary template chip with negative-relief features having dimensions of a scale in the micron range. The intermediary template chip is used to case a production mold, which is formed of a reinforced epoxy resin that, once hardened into a solid epoxy member, can withstand the structural pressures of a CNC machining system. The production mold can be refined by a CNC machining, where the refined production mold is then used to cast production chips to be used as microfluidic chips.
