The Automatic Thermocycling dipping machine is designed for simulation of oral temperature changes. The sample is immersed cyclically in baths of hot, warm and cold fluids. The machine is controlled by programmable logic controller (PLC) system with a touch screen as the interface for users. A simulation cycle was built as a mobile arm with a basket of one or more profiles, where the user can select two or three types of temperature. All six tanks are independent of each other and can be controlled via a touch screen.
