FLOW CELL AND PROCESS FOR PRODUCING THE SAME

摘要

[PROBLEMS] To provide a flow cell that is free from liquid leakage and excels in chemical resistance. [MEANS FOR SOLVING PROBLEMS] There is provided a preferred form of flow cell comprising flat-plate glass substrate (3); adherent fluororesin sheet (5) having a groove as flow channel (7) made by cutting machining; and glass substrate (1) as lid member furnished with through-holes (9,11) as fluid inlet and outlet at positions corresponding to both end portions of the groove. The fluororesin sheet (5) is interposed between the glass substrates (1,3) and, while heating at a temperature not lower than the melting point of the fluororesin sheet (5), pressurized so that the glass substrates (1,3) are bonded together by the fluororesin sheet (5) per se. Flow channel member (17) is constructed by the glass substrate (3) and, bonded thereonto, the fluororesin sheet (5).
