TITRATION DEVICE AND RICE INSPECTION METHOD USING SAME
The purpose of the present invention is to obtain a titration device which is compact and capable of performing titration on a small amount of a sample to be titrated. This titration device (10) is configured by joining a transparent resin layer (30) on a flat substrate (11). In this configuration, titrant (50) flowing through a titrant transport path (41) flows as plugs (51) in a first plug transport path (43). The sizes (volumes) of and the intervals between the plugs (51) are uneven. However, the plugs (51) are reconstructed as plugs (52) at a volume regulating section (44) so as to have even sizes, and these plugs (52) are poured into a reaction vessel (20) through a second plug transport path (45).
