Overview
The Magnetic Stirrer, model 84-1A4, features four mixing stations that can be used simultaneously or individually, each with independent speed regulation.
Features
1. Four stirring stations can be used simultaneously or alone; 2. Each station is independently regulated; 3. Max. stirring Capacity is 2L * 4; 4. Stirring speed range is 50~ 1700rpm; 5. Motor torque is 40mN · M; 6. Working mode is continuous operation.
Principle
The Magnetic Stirrer generates a swirl/spin magnetic field through motor drive, so that the stirrer in the container swirl/spin to achieve liquid stirring. The stirrer needs to be selected according to the shape of the container, the cylindrical stirrer is used for the flat-bottomed container, and the spherical container is used for the spun chute stirrer.
Steps
1. Trial run: connect the power supply, turn on the power switch, adjust the speed knob clockwise, check whether the motor rotation is normal, if any abnormality needs to be excluded; 2. Stirring operation: lay the machine flat, the container is placed in the center of the table, put in the appropriate stirrer, turn on and gradually accelerate; 3. After use, unplug the power supply, clean the appearance, and keep it after chilling down.
Notice
• The power supply needs to be reliably grounded; • The solution in the container should not be overfilled to avoid overflow during stirring; • The container should not be made of iron or magnetic materials, and the bottom thickness should not be greater than 10mm and smooth; • The stirring Rotation speed should be gradually accelerated from slow to fast to avoid the stirrer escaping; • If the stirrer is not in the center, it can be temporarily turned on and idled to suck it into the center.
