Patent ID: 8168135

Claim:
A reaction container plate comprising: a container base constituted from a substrate including a plurality of reaction containers each having an opening on a surface thereof; a channel base provided on the surface of the container base to cover the reaction containers and having a plurality of introduction holes each provided above and positioned at the respective reaction container so as to penetrate from a top surface to a back surface thereof; and a channel cover having a hollow space on a surface thereof and provided on the channel base so that the surface having the hollow space faces the channel base to form only one introduction channel constituted from the hollow space and the top surface of the channel base, the introduction channel being configured to pass above all the introduction holes, wherein the introduction channel is hermetically sealable, wherein each of the introduction holes has such an inner diameter that prevents a liquid from passing through it when an inside of the introduction channel is at an introduction pressure at which the liquid is introduced into the introduction channel but permits the liquid to pass through it to inject the liquid contained in the introduction channel into the respective reaction container when the inside of the introduction channel is pressurized so that a pressure in the introduction channel is made higher than the introduction pressure, and wherein the channel cover has a plurality of flexible portions each having a recess provided in the surface thereof facing the channel base, the recess being arranged to correspond to each of the introduction holes, the flexible portions being pressed from above toward the channel base to pressurize the inside of the introduction channel to inject the liquid contained in the introduction channel into the reaction containers through the introduction holes.
