A reaction processor is provided with a reaction processing vessel in which a channel is formed, a liquid feeding system, a temperature control system for providing a high temperature region and a low temperature region to the channel, and a fluorescence detector for detecting the sample passing through a fluorescence detection region of the channel, and a CPU for controlling the liquid feeding system based on a signal that is detected. A target stop position X.sup.[L].sub.0(n+1) of the sample in the low temperature region in an (n+1)th cycle is corrected from a target stop position X.sup.[L].sub.0(n) of the sample in the low temperature region in the nth cycle based on the result of stopping control on the sample in the nth cycle.

Provided is a device for measuring a microfluid flow velocity, having a structure separable by an ultra-thin film, the device including a first panel including a flow velocity measurement structure configured to measure a flow velocity of a fluid, a second panel configured to be separated from the first panel and including a microfluid channel through which a sample passes, and the ultra-thin film formed in a portion where the first panel and the second panel adjoin each other, the ultra-thin film being configured to separate the first panel and the second panel so that the sample passing through the microfluid channel does not come into direct contact with the flow velocity measurement structure, in which the first panel including the flow velocity measurement structure is usable multiple times repeatedly.

The present disclosure provide a detection device of microfluidic polymerase chain reaction (PCR) and a detection system including the same.
