The Magnetic Stirrer 85-1 consists of a flat plate or platform that contains a rotating magnetic field. When placed on the plate, a magnetic stirring bar or flea is immersed in the liquid, and the rotating magnetic field causes the stirring bar to spin, creating turbulence and mixing the liquid.

Features:

1. Flat Plate Design: The Magnetic Stirrer typically features a flat plate or platform where containers holding liquids can be placed for stirring.
2. Rotating Magnetic Field: The stirrer generates a rotating magnetic field, usually produced by an electromagnet or a series of rotating magnets beneath the plate.
3. Magnetic Stirring Bar: Included with the stirrer, a magnetic stirring bar or flea is a small, cylindrical magnet that is placed in the liquid to be stirred. The rotating magnetic field causes the stirring bar to spin, thereby stirring the liquid.
4. Variable Speed Control: Many magnetic stirrers offer variable speed control, allowing users to adjust the stirring speed according to their specific requirements.
5. Heating Capability: Some models of magnetic stirrers come with a heating element integrated into the plate, allowing for simultaneous stirring and heating of the liquid samples.
6. Digital Display: Advanced magnetic stirrers may feature a digital display that indicates the current stirring speed, temperature (if equipped with a heating element), and other settings.
7. Safety Features: Certain magnetic stirrers include safety features such as overheating protection and automatic shutoff mechanisms to prevent accidents or damage to the equipment.
8. Compact and Portable: Magnetic stirrers are typically compact and lightweight, making them easy to move and suitable for use in various laboratory settings.
9. Versatile Applications: Magnetic stirrers are widely used in research laboratories, educational institutions, pharmaceutical industries, and other scientific settings for mixing and stirring solutions, suspensions, and other liquid samples.

Overall, the Magnetic Stirrer 85-1 is a versatile laboratory instrument that offers efficient and uniform mixing of liquids, making it an essential tool for various scientific and industrial applications.
