An innovative polymerase chain reaction (PCR) thermocycler using pressurized gas through a Ranque-Hilsch vortex tube is described below. This device can amplify 10pg of 186bp Escherichia coli uidA amplicon in a 20 μL sample 3.3 × 108-fold, by performing 35 cycles in less than 8 min. This PCR amplification corresponds to an overall efficiency of 75%.
