Abstract
Apparatus are disclosed that thermally cycles samples between at least two temperatures. These apparatus operate by impinging fluid jets onto the outer walls of a sample containing region. Because the impinging fluid jets provide a high heat transfer coefficient between the jet and the sample containing region, the sample containing regions are uniformly cycled between the two temperatures. The heat exchange rate between the jets and the sample regions are substantially uniform.
