摘要: A coaxial-drive centrifuge provides for contactless regulation of sample temperature. The is contained in a multi-station chemical-processing circuit that has metal receptor at each station. On demand, stationary inductor induces eddy currents the as it spins by. Dissipation current heats and surrounding sample. thermal sensor an optical indication reader reads indication. controller activates when reading indicates actual temperature below predetermined target When heating required, pulsed aligned with gap inductor. designed specific series chemical reactions, this case, polymerase chain reaction (PCR) implement iterated three steps. To end, stations arranged closed loop interconnecting channels. treatment completed, tilts so to next station treatment. Each its own thermo-sensor can be performed respective optimal system thus automating sequence processes using
