发明名称 | Fluid-controlling device for microchip and use thereof | ||
摘要 | The present invention relates to a fluid-controlling device (10) for incorporation into a microchip (100). The fluid-controlling device (10) of the present invention includes: a glass substrate (1b) having a hollow part (3) provided therein, the hollow part (3) having a first opening (3′) extending to a top surface of the glass substrate (1b) and a second opening (4) extending to a bottom surface of the glass substrate (1b); and a glass sheet (2) being 1 to 50 μm in thickness and sealing the first opening (3′), the glass sheet (2) changing a volume of the hollow part (3) when a position of the glass sheet (2) is displaced by and according to a pressing force applied toward the hollow part (3). With use of the present invention, it is possible to provide a versatile microchip system being usable under a high pressure and being usable with an organic solvent. | ||

主权项 | 1. A fluid-controlling device for microchip, the fluid-controlling device comprising: a glass substrate and a glass sheet which is 1 μm to 50 μm in thickness; and a recessed part provided in the glass substrate having a first opening formed on a top-surface side of the glass substrate, and a first port and a second port configured to serve as a second opening being formed on a bottom of the recessed part, the glass sheet sealing the first opening, wherein when a pressing force toward an inside of the recessed part is applied to the glass sheet, a volume of the recessed part is decreased, and when the pressing force is released, the volume of the recessed part is restored, and the first port and the second port are located at respective positions to be sealed by the glass sheet when the glass sheet is pressed to the bottom of the recessed part. | ||
