Problems solved by technology

As a result, there is a problem that there is variation among the amounts of sample solutions introduced into the respective wells, etc., thereby reducing analysis precision and analysis efficiency
In addition, when heating a sample like PCR, there is a problem that air bubbles present in the trap etc. expand to interfere with the reaction, thereby reducing the analysis accuracy

Abstract

A sample liquid supply container is disclosed. The sample liquid supply container includes a first region which is depressurized therein and is hermetically sealed, a second region which is able to receive a liquid therein, a first penetration portion, in which an interior of the first region is punctured by a hollow needle from outside, and a second penetration portion, in which an interior of the second region is punctured by the hollow needle inserted into the first penetration portion and reaches inside the first region.

Description

technical field [0001] The present invention relates to a sample liquid supply container, a sample liquid supply container assembly and a microchip assembly. More specifically, the present invention relates to a sample liquid supply container, etc., which can easily perform liquid injection into a region formed in a microchip. Background technique [0002] In recent years, microchips have been developed in which wells and / or flow paths for chemical or biological analysis are provided on silicon substrates or glass substrates by applying micromachining techniques used in the semiconductor industry, (for example, refer to Japanese Unexamined Patent Application Publication No. 2004-219199). These microchips have begun to be used in electrochemical detectors in liquid chromatography, electrochemical sensors in medical service sites, etc. [0003] Analysis systems using such microchips are called μ-TAS (Micro Total Analysis System), lab-on-a-chip (lab-on-a-chip), biochip, etc. ...
