The purpose of this system is to regulate the substance's temperature inside the syringe to the designated temperature given by the user.

The temperature is sampled off the container, which is connected to the syringe, using a temperature. A heat resistor is attached to the container to generate heat. When the sampled temperature is higher than the one designated then the current to the resistor is cut off leading to its cool down. When the temperature is below the designated one then the current is renewed leading to the rise of temperature. The current is controlled by the use of a transistor. When there is a need to cut off the current then the transistor is not active otherwise the transistor is active.
