Precautions for use
Equipment inspection and preparation
Equipment integrity check
Before use, you should carefully check whether the magnetic stirrer and its accessories are intact, especially the key components such as the mixer and the power cord.
Environmental adaptability check
Ensure that the magnetic stirrer is placed on a smooth, dry, well-ventilated workbench, away from flammable and explosive materials.
Power check
Confirm that the power supply voltage is consistent with the rated voltage of the magnetic stirrer, the plug and socket are well connected, and there is no damage or leakage.
The operation process precautions
When holding the solution in the container, the liquid volume should not be too full, and it is generally recommended not to exceed two-thirds of the container volume to prevent liquid spatter or overflow during the mixing process.
According to the nature of the solution and the shape of the container, select the appropriate ptfe magnetic stirrer. Sink the blender into the bottom of the container, making sure it is in close contact with the bottom of the container.
After opening the magnetic stirrer, the speed control knob should be gradually adjusted, starting from the low speed and gradually increasing to the required speed. Avoid sudden acceleration resulting in liquid splatter or out-of-control mixer.
For magnetic agitators with heating functions, the temperature knob should be set correctly and the heating temperature should be adjusted according to the needs of the experiment. At the same time, it is necessary to check the accuracy and position of the temperature measurement probe regularly to avoid damage caused by the agitator colliding with the probe.
If timing mixing is required, the timing switch should be set correctly and the magnetic stirrer should be turned off in time after the timing is over.
Safety protection measures
Personal protection
Operators should wear appropriate personal protective equipment, such as lab coats, gloves, goggles, etc., to prevent the solution from splashing into the eyes or skin.
Electrical safety
Ensure that the magnetic stirrer is well grounded to avoid the risk of electric shock due to electrical failure. During operation, avoid touching the power plug or switch with wet hands.
Fireproof and explosion-proof
For flammable and explosive solutions, the heating temperature and stirring speed should be strictly controlled to avoid sparks or high temperature hazards.
Emergency treatment
In the process of use, if abnormal conditions are found (such as solution overflow, stirrer fracture, etc.), the magnetic stirrer should be turned off immediately, and the necessary emergency treatment measures should be taken.
Maintenance and maintenance
Regular cleaning
After use, the mixer and container should be cleaned in time to keep the equipment clean and dry. At the same time, wipe the surface of the magnetic stirrer with a clean cloth to avoid corrosion caused by solution residue.
Check the magnetic mixer
Regularly check the magnetic strength of the magnetic mixer, such as magnetic weakening should be replaced in time to ensure the mixing effect.
Storage precautions
Store the magnetic stirrer in a dry and well-ventilated environment, away from direct sunlight and high temperature and humidity. When not used for a long time, the power plug should be unplugged.
Special precautions
Solution compatibility: Although the teflon mixer has good chemical stability, it is still necessary to confirm that the material of the mixer will not be corroded when using special solvents (such as some highly corrosive acids or bases).
Avoid interference: When using magnetic stirrer and other instruments (such as thermometers, pH electrodes, etc.) in the container at the same time, attention should be paid to the mutual position between them to avoid interfering with the rotation of the magnetic stirrer or causing collision damage.
