Overview
SILE INTRUMENT 81-2 Magnetic Stirrer is a device with smooth Rotation speed and stepless speed regulation, which can be automatically thermostatic and the heating speed can be adjusted arbitrarily. This product is widely used in chemical industry, scientific research and teaching fields.
Features
1. Rotation speed smooth, stepless speed regulation
2. Automatic thermostatic function
3. The heating speed can be adjusted arbitrarily
4. Max. Capacity of stirring 3L
5. stirring speed range 100~ 1300rpm
6. Heating power 400W
7. Temperature range RT +~ 100 ℃
8. Temperature control accuracy +/- 1 ℃
9. Continuous working mode
10. Motor torque 12.5mN · M
Principle
The stirring function is realized by the magnetic drive stirrer swirling/spinning in the container, and the heating and thermostatic control are realized by the heater heating and temperature control system.
Applications
Chemical industry, scientific research, teaching
Steps
1. Lay the machine flat, put the container with the solution in the center of the instrument disc, put the appropriate stirrer in the container, the container should not be made of iron and magnetic related materials
2. Plug in the power supply, turn on the power switch, the power indicator light is on, turn on the stirring switch, the stirring indicator light is on, and adjust the speed regulation knob clockwise. The instrument runs from slow to fast, and it needs to be gradually accelerated when adjusting the speed.
3. If the solution needs to be heated while stirring, the two-core plug can be inserted into the thermometer jack behind the machine, the heating indicator light is on, the heater heats up, and the Heating power is adjusted by the temperature control knob
4. If the solution needs to be automatically thermostatic, the user needs to self-distribute the electric contact mercury-filledthermometer, solder its two leads to the two-core plug, and insert it into the solution, and fix it on the watch rod with a testtube clip. The thermometer cannot touch the swirl/spin stirrer. After setting the required temperature, it can achieve automatic thermostatic.
5. After the instrument is used, unplug the power supply, and keep it properly after chilling down
Notice
• The power supply needs to be reliably grounded
• The solution in the container should not be overfilled to avoid overflow when stirring
• This instrument cannot be used as a heater alone
• Containers must not be made of iron or magnetic materials
• When adjusting the speed, it is necessary to gradually accelerate. If the acceleration is too fast, it is easy for the stirrer to escape
• Electric contact mercury-filledthermometer Glass instrument, extremely fragile
• When the solution with a lower set temperature is less, the temperature rises to the set temperature, and the heater has been powered off, but the solution temperature may still rise, affecting the temperature control accuracy. At this time, the Heating power can be appropriately lowered
