Abstract
An integral heated reaction chamber for use in a unified fluid circuit having an acrylic body. The acrylic body is preferably formed of first and second acrylic layers bonded or fused together. A chamber half is formed in each of the acrylic layers and the layers are bonded together in opposition. A thinning notch is provided in one of the acrylic layers to form a thin wall of the chamber, and a heater element is secured adjacent the thin wall to heat the contents of the chamber. A temperature sensor is provided to monitor the temperature of the chamber contents. The sensed temperature may be used to control the heating element and the heating time according to a predetermined reaction protocol.
