Patent ID: 8021843

Claim:
A biological sample reaction method that utilizes a biological micro reaction array, the method comprising the steps of: supplying a reaction solution through a first opening into a first channel of the array having a capillary force defined as A; filling a plurality of reaction vessels of the array with the reaction solution, a capillary force of first connected portions between the reaction vessels and the first channel is defined as B and a capillary force of the reaction vessels is defined as C; filling the first channel and a second channel of the array with a liquid that is both immiscible with the reaction solution and evaporates more slowly than the reaction solution, the first channel is connected to a first end of each of the reaction vessels and the second channel is connected to a second end of each of the reaction vessels, a capillary force of second connected portions between the second channel and the reaction vessels is defined as D, and a capillary force of the second channel is defined as E, wherein A<B<C<D and E<D; and performing biological sample reaction processing.
