Abstract

Compressed gas is supplied from above to a specimen vessel having an open top. Transfer channels to reaction vessels are provided under a microchip and transfer channels extending from the reaction vessels are provided on the microchip. Transfer element is provided outside the microchip so as to supply the compressed gas from a member (cover) holding the microchip.

Description

[0001] This application is a divisional application, the application number of its parent application is: 200880007064.7, the filing date: 2008.3.4, the name of the invention: microchip fluid control mechanism. technical field [0002] The present invention relates to a fluid control mechanism and a fluid control method of a microchip, in particular to a plurality of reaction tanks and sample tanks for reaction / mixing / separation / analysis of chemical samples, or gene analysis, etc. A micro-analysis chip that connects the flow path between the reaction tank and the sample tank. Background technique [0003] In recent years, as recorded in Zhuangzi Xiyi's "Biochemical Microchemical Analysis System Micromachine Technology" (non-patent document 1) or JP-A-2002-214241 (patent document 2), in microreactors, microarrays and known as " There are more and more studies on gene analysis by reacting samples or liquid samples on a tiny chip of "Lab on a chip", and studies have been made o...
