Instructions for use：

After connecting the power, turn on the power switch. Preheat the heating center seat, wait for the indicator light to turn off, add 5ml of solution to the Ø 16 × 150 test tube, insert it into the heating hole from above, and after about 10 minutes, the solution reaches boiling state. Use a test tube clamp to remove it and repeatedly use it. After the experiment is completed, the power should be turned off and there should be no idle heating. Prevent the casing from becoming too hot and causing burns to the human body during prolonged work. The heater is equipped with a temperature inside, which automatically adjusts the heating temperature of the heating coil (indicated by an indicator light)
