Overview
CHIJIU H01-3 thermostatic Magnetic Stirrer is driven by brushless DC motor, with strong Stir force and high power adjustable heating function, suitable for Stir and heating of high temperature and high viscosity liquids, the maximum Stir capacity can reach 10000ml.
Features
1. Adopt brushless DC motor for strong power.
2, equipped with high-power adjustable heater, heating power can be adjusted within 800W.
3. Stirring capacity is large, up to 10L.
4. Wide speed adjustment range, continuously adjustable from 0 to 2000rpm.
5. Support automatic temperature control function (external electrical contact mercury-filledthermometer is required).
6. Motor torque up to 25mN · M, Stirring force.
Principle
The device drives the internal magnet to generate a swirl/spin magnetic field through a brushless DC motor, which drives the magnetic Stir placed in the container to synchronize the swirl/spin, so as to realize the Stir of the liquid. At the same time, the heater at the bottom of the device provides a heat source to heat the container, and the heating power can be adjusted through the knob. When the external electrical contact mercury-filledthermometer is connected, the thermostatic control that automatically stops heating when it reaches the preset temperature and automatically resumes heating when it falls below the preset temperature can be realized.
Applications
Laboratory Liquid Stirring, Chemical Synthesis, Sample Preparative, Solution Mixing, Heating Reaction
Standards
Power frequency: AC220V +/- 10% 50Hz
Steps
1. Place the Stirrer smoothly, put the Stir in the beaker and place it in the center of the workbench, adjust all knobs counterclockwise to the minimum, connect the power supply and turn on the power switch.
2. Slowly swirl/spin the speed knob clockwise, start and adjust the stirring speed.
3. When heating is required, turn the button switch down, adjust the temperature control knob to control the heating power, and the voltmeter shows the heating voltage.
4. When automatic temperature control is required, connect the electrical contact mercury-filledthermometer (self-provided) to the rear terminal of the machine, insert the thermometer Probe into the liquid medicine and fix it, turn the button switch down, and the device can automatically start and stop heating according to the set temperature.
5. After use, disconnect the power supply and clean the collection after the equipment is chilled down.
Notice
• Power sockets must be well grounded.
• Avoid use in humid environments.
• Stir, the beaker should not be too full to prevent overflow.
• This equipment shall not be used as a heater alone.
• During automatic temperature control, due to the thermal inertia of the heater, the temperature control accuracy may be affected, and the heating power can be appropriately lowered to improve.
• When heating, the maximum temperature on the surface of the heater exceeds 300 ° C, and the temperature that the liquid medicine can actually reach is inversely proportional to its capacity.
