Tarson Round Magnetic Stirrer Bar with Pivot Ring, PTFE / Alnico V Magnet

The "Tarson Round Magnetic Stirrer Bar with Pivot Ring" is a laboratory tool used in conjunction with magnetic stirrers for stirring liquids in various vessels. Here's what you can expect from this magnetic stirrer bar:

1. Round Shape: The stirrer bar has a round shape, allowing it to efficiently stir liquids in vessels such as beakers, flasks, and test tubes.

2. Pivot Ring: The stirrer bar is equipped with a pivot ring, which helps to center the bar and maintain stability during stirring. The pivot ring also minimizes friction between the bar and the vessel, reducing wear and tear.

3. Material: The stirrer bar is made from PTFE (Polytetrafluoroethylene) and Alnico V magnet. PTFE is a chemically resistant material commonly used in laboratory equipment due to its inertness and non-reactivity with most chemicals. Alnico V is a type of magnet known for its strong magnetic properties and resistance to demagnetization.

4. Magnetic: The stirrer bar contains a magnet (Alnico V) inside, allowing it to be attracted and rotated by the magnetic field generated by the magnetic stirrer.

5. Chemical Compatibility: The PTFE material ensures that the stirrer bar is chemically compatible with a wide range of substances, making it suitable for stirring both acidic and basic solutions, as well as organic solvents.

6. Versatility: The stirrer bar can be used in various laboratory applications that require mixing or stirring of liquids, including sample preparation, chemical synthesis, dissolution, and titration.

7. Size: The stirrer bar comes in different sizes, allowing users to select the appropriate size based on the volume and shape of the vessel being stirred.

Overall, the Tarson Round Magnetic Stirrer Bar with Pivot Ring provides a reliable and efficient solution for stirring liquids in laboratory settings. Its durable construction, chemical compatibility, and magnetic properties make it a versatile tool for various laboratory applications.
