    Abstract: PROBLEM TO BE SOLVED: To provide a cartridge which can quickly treat a reactant mixture and improve the detection sensitivity of an analyte in the mixture. SOLUTION: This cartridge (20) for controlling a chemical reaction includes a main body with at least one internally-formed channel The cartridge extends from the main body, and further includes a reaction container (40) for holding the reactant mixture used on the chemical reaction and optical detection. The reaction container (40) has a rigid frame for partitioning sidewalls of a reaction chamber, and the frame has at least one channel for connecting the channel with the reaction chamber. Furthermore, the reaction chamber has flexible films or sheets attached to both sides of the above frame in order to form a main wall opposed to the reaction chamber. Additionally, at least two of the sidewalls are biased with respect to each other so as to be translucent and angular for enabling the real time optical detection of the analyte in the reaction chamber.

    Abstract: A sample-processing device (150) comprises a unitary body (152), preferably a molded polymeric part, having formed therein a reaction chamber (154) for chemically reacting a sample, a separation region (158) for separating components of the sample, and a transition region (156) connecting the reaction chamber (154) to the separation region (158). The reaction chamber (154), transition region (156), and separation region (158) are formed in and enclosed by the unitary body (152). Additionally, the transition region (156) includes at least one flow restrictor (180) for controlling the flow of fluid between the reaction chamber (154) and the separation region (158). Further, the portion of the unitary body (152) defining the transition region (156) has lower thermal conduction than the portion of the body defining the reaction chamber (154) so that the transition region (156) thermally isolates the reaction chamber (154) from the separation region (156). In a preferred embodiment, the reaction chamber (154) is an amplification chamber for amplifying nucleic acid in the sample, and the separation region (158) comprises an electrophoresis column or capillary containing a suitable matrix material, such as electrophoresis gel or buffer, for separating nucleic acid fragments in the sample. Electrodes (167, 168, 169) are embedded in the body (152) for forcing the sample to flow from the reaction chamber (154) to the separation region (158). The unitary body (152) may also be surrounded by external, functional components such as an optical detector (186) for detecting separated components of the sample.

    Abstract: A multi-site reactor system (60) provides dynamic, independent, computer-implemented control of each reaction site, permitting different thermal profiles to be performed on samples at different reaction sites simultaneously. The system includes reaction vessels (2) for holding reaction mixtures and heat-exchanging modules (37) for receiving the vessels. The system also includes a controller (64) for independently controlling each heat-exchanging module (37) to heat and/or cool the reaction mixture contained therein. The controller (64) includes an adaptive control program for dynamically adjusting the duration or intensity of power pulses provided to each heating element and for dynamically adjusting the duration of fan operation to attain target temperatures quickly and accurately without overshooting or undershooting the target.
