Temperature controlled chamber for diagnostic analyzer

摘要: A temperature controlled chamber (36) for an analytical instrument which includes a circular conveyor (24) transporting assay cartridges (22), the enclosing outer peripheral part of on (22) reside. The comprises bottom wall (80) polymeric material located beneath (24), (82) extending upward above metallic top (78) and inner (84) extends downward to upper surface (24). Thermal control, including rapid thermal response compensate perturbations induced by periodic introduction are at less than that (36), is accomplished heating elements (96, 98) below conveyor. pulsed electrical circuit rate substantially faster new cartridges. Pulses electric current applied modulated with pulse-width modulation adjust within in signals emitted sensor chamber.
