Claim Text:
1. A reaction tube, comprising: an upper section for receiving a reagent; a lower capillary section for performing an isothermal polymerase chain reaction therein, having: a linkage connecting the upper section and the lower capillary section, wherein the annealing portion is connected with the linkage; and a thermal conductor tightly embracing the annular heating groove of the lower capillary section for conducting heat thereto from a heating source, wherein the thermal conductor is received by the annular heating groove; wherein a heat generated from the heating source will be evenly conducted to the annular heating groove of the lower capillary section of the reaction tube, and the lower capillary section is only heated by the heat received at the annular heating groove; whereby a temperature gradient involving a reduction of temperature from the bottom part of the lower capillary section to a top part the lower capillary section is then provided in order to perform a thermal convection, hence the thermal convection results in three events, (i) denaturation, (ii) annealing and (iii) extension, occurring repeatedly in different regions of a PCR sample, thereby performing the isothermal polymerase chain reaction in the lower capillary section.
