Operation method of multiplex slide plate device

An operation method of a multiplex slide plate device is provided. First, the multiplex slide plate device is assembled, including a slide plate, a sacrificial layer and a housing. The slide plate has reaction vessels, and the sacrificial layer has a microfluidic channel composed of an injection channel, a main channel and a distal channel. A sample solution is injected to the injection channel, such that the sample solution flows from the injection channel through the main channel to the distal channel, wherein the sample solution loads into the reaction vessels. Afterwards, an oil is injected to the injection channel, such that the oil flows from the injection channel through the main channel to the distal channel, wherein the oil removes the sample solution not loaded into the reaction vessels. Next, the sacrificial layer is heated to melt, and the melted sacrificial layer is mixed with the oil.
