PCR reaction container
A PCR vessel having: a substrate, a flow channel formed in the substrate, a pair of filters provided at both ends of the flow channel, a pair of air communication ports communicating with the flow channel through the filters, a thermal cycle region formed between the pair of filters in the flow channel, and a sample injection port through which a sample can be injected into the flow channel from above; wherein the sample injection port in the surface of the substrate has an area of 0.7 to 1.8 mm 2 .
1. A PCR vessel comprising:
a substrate comprising a surface,
a flow channel formed in the substrate,
a pair of filters provided at both ends of the flow channel,
a pair of air communication ports communicating with the flow channel through the filters,
a thermal cycle region that is in the flow channel between the pair of filters where heat is applied, and
a sample injection port formed to connect the surface of the substrate and the flow channel through which a sample can be injected into the flow channel between one of the filters and the thermal cycle region, without mediating a branch flow channel, wherein the sample injection port in the surface of the substrate has an area of 0.7 mm 2 to 1.8 mm 2 .
