<p>Apparatus is disclosed that thermally cycles samples between at least two temperatures. The apparatus operates 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 is substantially greater than in the case of laminar flow.</p> |
