What Should You Watch for When Using a Magnetic Stirrer?

　　Magnetic Stirrers provide stirring alone or simultaneous heating and stirring for low-viscosity liquids and solid-liquid mixtures. A magnetic field generated by the base rotates a stir bar inside the vessel to mix the sample. With temperature control, sample temperature can be set and maintained according to the experiment, helping reproduce experimental conditions.

　　The following is a brief introduction:

　　I. Before first use, check the supplied accessories against the manual, including the stir bar and power cable.

　　II. Increase speed gradually from low to high. Avoid starting directly at high speed, which may cause the stir bar to lose coupling and jump.

　　III. Moderate-speed operation can extend the stirrer's service life.

　　IV. Keep the instrument clean and dry, especially preventing liquid from entering the housing.

　　V. If the stir bar jumps or fails to stir, check that the beaker is stable and correctly centered.

　　VI. Connect the earth wire during use.

　　VII. Do not heat without stirring. Disconnect power when the instrument is not in use.
