The constant temperature magnetic stirrer adopts DC three-phase motor constant speed control, so the stirring performance is better, especially at low speed, it can start and run at 50 rpm.

Stirring operation: put the container containing the solution in the center of the workbench (that is, the electric furnace), put a suitable stirring bar in the container, (it needs to be sucked into the center, use a cylindrical stirring bar for a flat-bottomed container, and use a spinning stirrer for a spherical container ) to start up and run, the switch is on the left side of the fuselage. The container should not be made of iron or materials related to magnetism, the thickness of the bottom should not be greater than 10mm, and it should be smooth. Adjust the speed control knob and the stirring speed should be gradually accelerated from slow to fast. If the acceleration is too fast, the stirring bar will easily escape. If the stirring bar is not in the center of the container, you can turn on the stirrer first, let it idle for a while and then turn it off, the stirring bar will automatically suck into the center.
