We have 2 deliverables for our final design. The first one is an "all-in-one" device which includes temperature control, magnetic stirring and ultrasonic bath. The second one is a combined temperature controller and magnetic stirrer.
The "All-in-one" device has a built-in heater that can heat up to 80 degree Celsius. In this project 37 degree Celsius is the required temperature for enzymes to work at an optimal level. The ultrasonic cleaner can be filled with coupling fluid such as distilled water and it provides a 40kHz agitation with its built-in ultrasonic transducer.
The combined temperature controller and magnetic stirrer is programmable for different stirring speeds. Users can control the settings through a Graphical User Interface in the Raspberry Pi touchscreen display.
A 6061 aluminum prototype heater block of 3 vial wells was tested. It heated up to 37 degree C in less than 5 minutes and maintain 37 plus or minus one degree throughout the hour. The dip was caused by the evaporation of water inside the vial wells. The temperature went back to around 37 deg C after water was refilled, and remained constant for the rest of the time.
