The “Magnet for Magnetic Stirrer, Coated, 12x3mm” is a cylindrical magnet with dimensions of 12 millimeters in diameter and 3 millimeters in height. It is coated with a protective layer, often made of PTFE (polytetrafluoroethylene) or similar materials, to prevent corrosion and ensure compatibility with various solvents and chemicals used in laboratory experiments.

Features:

1. Cylindrical Design: The magnet is shaped like a cylinder, which allows it to generate a magnetic field when placed on a magnetic stirrer’s plate.
2. Coated Surface: The magnet is coated with a protective layer, typically PTFE or a similar chemical-resistant material, to prevent corrosion and damage from exposure to harsh chemicals and solvents.
3. Compatible Size: With dimensions of 12x3mm, the magnet is compatible with most magnetic stirrers commonly used in laboratory settings.
4. Strong Magnetic Force: Despite its small size, the magnet provides sufficient magnetic force to effectively stir liquids in laboratory vessels, such as beakers, flasks, and test tubes.
5. Chemical Resistance: The coating material provides excellent resistance to various chemicals and solvents, ensuring durability and longevity even when used in aggressive laboratory environments.
6. Versatile Applications: The magnet is suitable for a wide range of laboratory applications, including mixing, stirring, and blending of liquids and solutions in chemistry, biology, pharmaceuticals, and other scientific disciplines.
7. Easy to Clean: The coated surface of the magnet is easy to clean and maintain, allowing for reuse in multiple experiments without cross-contamination.
8. Replacement Option: The magnet can serve as a replacement or spare part for magnetic stirrers, ensuring uninterrupted operation in laboratory settings.

Overall, the “Magnet for Magnetic Stirrer, Coated, 12x3mm” offers a reliable and convenient solution for stirring and mixing liquids in laboratory experiments, providing chemical resistance, compatibility, and durability for a wide range of scientific applications.
