Choose well-known brands and suppliers that provide high-quality after-sales service.
► Maintenance methods
In order to ensure its long-term stable operation and extend its service life, regular maintenance and upkeep are required. Here are some common maintenance methods:
Regular cleaning:
After use, wipe the surface of the heating plate and mixer with a soft cloth to avoid using corrosive cleaning agents;
Check the power cord:
Regularly inspect the power cord for damage or aging, and replace it promptly if there are any abnormalities;
Calibration temperature:
Regularly calibrate the equipment with a standard thermometer to ensure temperature control accuracy;
► Storage and protection
Proper storage:
When not in use, the device should be placed in a dry, ventilated, dust-free environment, away from direct sunlight and moisture. At the same time, it is necessary to ensure that the equipment is in a horizontal state to prevent damage to internal components due to long-term tilting.
Dust and dirt prevention:
Cover the equipment with a dust cover or clean cloth to reduce the accumulation of dust and impurities. Regularly clean up the debris around the equipment and keep the work area clean.
► Regular inspection and maintenance
Motor and magnetic system:
Although the magnetic stirring system does not require direct contact, it is still necessary to check whether the magnetic force has weakened or whether the stirring element has worn out after long-term use. If necessary, a new stirrer can be replaced. At the same time, check whether the motor runs smoothly and whether there are any abnormal noises or vibrations.
Heating element:
Check for any signs of damage or aging, such as discoloration, deformation, or burning. If there is any abnormality, please contact the manufacturer for repair or replacement in a timely manner.
Control system:
Check whether the control panel, display screen, buttons and other components are sensitive and reliable, and whether there is any damage or malfunction. Ensure clear and accurate display of numbers to avoid misoperation.
► Precautions
Avoid overload:
When using, do not place heavy or oversized containers on the heating plate to avoid exceeding the load-bearing capacity of the equipment and causing deformation or damage to the heating plate.
Uniform heating:
Try to ensure that the bottom of the container is in full contact with the heating plate to achieve uniform heating. For irregularly shaped containers, appropriate brackets or washers can be used to assist in fixing.
Avoid sudden cooling and heating:
During the heating process, avoid adding a large amount of cold water or ice cubes as a cold source to prevent impact and damage to the heating element.
Professional maintenance:
If the equipment malfunctions or needs maintenance, please be sure to contact professional maintenance personnel or manufacturers for handling. Do not disassemble or repair it yourself.
Digital hotplate magnetic stirrer common faults and solutions
► The mixer does not rotate
1) Check the motor: If the motor is damaged, replace the motor. If the motor is poorly lubricated, it should be refueled and maintained.
2) Check the circuit: Check whether the high-power components on the circuit board are damaged, such as 3DD102, and replace the damaged components if necessary. Check whether the diode in the rectifier circuit is short-circuited, and repair or replace the short-circuited diode.
3) Check the transformer: If the transformer is burned out, replace the transformer.
4) Check stirrer and magnetic field: Make sure the blender is centered in the container and snug against the bottom. Increasing the mixer speed too fast may cause the mixer to decouple from the magnet, and the speed should be increased slowly.
► Heating without heating
1) Check the heating ring: If the heating ring is short-circuited or disconnected, replace the heating ring.
2) Check the fuse: If the fuse is blown, check whether the transformer is burnt or short-circuited before replacing the fuse.
3) Check the temperature sensor: If the temperature sensor is damaged or faulty, replace it.
► Runaway speed
1) Check potentiometer: If the potentiometer is damaged or fails, replace the potentiometer.
2) Check the circuit board: If the circuit board is damaged, replace it.
► Temperature runaway
1) Check the heating tube: If the heating tube is burnt or damaged, replace the heating tube.
2) Check the digital display table: If the digital display is damaged or out of order, replace the digital display.
► Whole machine vibration
1) Check the rotor: If the rotor is unbalanced or damaged, replace the rotor.
2) Check the bearing: If the bearing is damaged or seriously worn, the bearing should be replaced.
► Loud noise
1) Check the motor: If the motor is poorly lubricated or corroded, the motor should be refueled and maintained or replaced.
2) Check mechanical parts: Check for loose or worn mechanical parts and tighten or replace them.

Make sure to use a three-phase safety outlet and check that the outlet is properly grounded. Grounding is an important measure to prevent electric shock, which can ensure that the current can safely flow into the ground when the equipment leaks, rather than through the human body.
► Avoid wet hands
Keep your hands dry when inserting or unplugging the power plug or performing other power related operations. Wet hands increase the risk of electric shock because water conducts electricity.
► Regular inspection of equipment
Check regularly whether the power cord, plug and socket of the magnetic stirrer are in good condition. If it is found to be worn, aged or damaged, it should be replaced immediately to avoid electric shock caused by equipment failure.
► Check before use
Before each use, check whether the control panel, heating plate and stirrer of the magnetic stirrer are working properly. Make sure there are no exposed wires or damaged parts to reduce the possibility of electric shock.
► Compliance with operating procedures
The experiment was carried out in strict accordance with the operating procedures of the magnetic stirrer. Do not arbitrarily change device parameters or perform non-standard operations to avoid electric shock accidents caused by improper operations.
► Wear protective equipment
Wear protective equipment such as lab clothes and gloves when performing experimental operations. These devices can provide additional protection and reduce the risk of electric shock.
► Pay attention to ventilation and drying
Ensure that the laboratory is well ventilated and that the magnetic stirrer and its surroundings are kept dry. Humid environments tend to increase the risk of electric shock because water conducts electricity.
► Cut off the power for maintenance
If the magnetic stirrer fails or needs maintenance, be sure to cut off the power first, and repair under the guidance of professionals. Do not attempt to disassemble or repair the equipment yourself to avoid electric shock or other injury.
► Regular maintenance and maintenance
Regular maintenance and maintenance of the magnetic stirrer, including cleaning equipment, checking for loose or damaged parts, etc. This ensures the proper operation of the equipment and reduces the risk of electric shock due to equipment failure.
