 SELLING POINT   
The smart magnetic stirrer can be flexibly set up with inter-changeable heating sleeves for 100mL,250mL,500mL,1000mL round-bottom flask, or 100mL,250mL, 500mL, 1000mL flat bottom beakers.
Even more flexible configurations: as one heating magnetic stirrer,
or as one heating sleeve plus one magnetic stirrer.
Temperature self calibration function for higher temperature accuracy.
Heating sleeve made of high-guality Aluminum silicate fiber cotton with
 accurate temperature control, uniform heating and corrosion resistance.
Strengthened magnetic fields with enhanced stirring power.
Fireproof metal outcast with higher safety level.
Explosion-proof DC brushless motor free of maintenance and spark, and with long service life.
The “HOT" warning will flash if the work plate temperature is above 50°C even
 when the hotplate is turned off, as long as the power cable is connected.
Two independent safety circuits are designed to continuously monitor the equipment.
 When the sensor malfunctions and overheating occurs, an error code will be generated
and the stirrer will stop heating. When the first safety circuit is shorted, the second
safety circuit will cut off the power supply to ensure the safety of the operator
Applications
Magnetic stirer with heating sleeve is a very popular product for laboratories in
scientific research, industry and mining, food processing, biochemistry, agriculture, petrochemical, pharmaceutical, and educational aspect. lt is used for heating and
 incubation of liquids at a certain temperature. lt provides fast and uniform heating with
highly precise temperature control and strong stiring power. lt can serve as a
magnetic stirrer with heating sleeve, or as a magnetic stirrer and a heating sleeve .
