The CNC constant temperature magnetic stirrer is a laboratory equipment that integrates "magnetic stirring" and "constant temperature heating". It precisely controls the speed and temperature through a CNC system and is suitable for experimental scenarios that require synchronous mixing and temperature control. Core working principle 1 Mixing mechanism: Using the principle of electromagnetic drive, the motor drives the internal magnetic steel to rotate, generating a rotating magnetic field. The magnetic field attracts the agitator inside the container to rotate synchronously, achieving uniform mixing of the sample. 2. Constant temperature mechanism: Heating elements (such as electric heating wires and ceramic heating plates) provide heat, and temperature sensors collect real-time temperature of the working plate. The numerical control system compares the set temperature with the actual temperature, automatically adjusts the heating power, and maintains temperature stability. 3. Numerical Control: The microcomputer chip receives setting instructions such as speed, temperature, and timing, and provides real-time feedback on parameters through the display screen to achieve precise control. ---Key feature - Dual function integration: simultaneously meets the requirements of mixing and constant temperature, without the need for additional heating equipment, simplifying the experimental process. -Accurate and controllable parameters: The speed range is usually 100-2000rpm, the temperature control accuracy can reach ± 0.1 ℃, the timing range is 0-99h, and it is suitable for different experimental requirements. -Easy to operate: equipped with LCD display and button/touch operation, some support parameter memory function, which can be directly called up next time used. -Safety design: It has functions such as over temperature protection and dry burn protection. The work disk is mostly made of corrosion-resistant materials (such as PTFE coating and stainless steel), with a long service life. -Wide adaptability: can be used with various containers such as beakers, flasks, centrifuge tubes, etc., supporting small to medium volume sample processing. ---Typical application scenario - Chemical synthesis: In organic reactions that require temperature controlled stirring, such as esterification and polymerization reactions. -Biological experiment: preheating and stirring of culture medium, temperature and mixing control of enzymatic reaction system. -Sample pretreatment: Constant temperature digestion and mixing of bulk samples in water quality analysis and food testing.7-inch aluminum plate constant temperature magnetic stirrer
