Fisher Scientific Round Stir Bar with Removable Pivot Ring 127 mm Length

The Fisher Scientific 14-512-138 Round Stir Bar is a laboratory accessory designed for efficient magnetic stirring of liquids in various vessels. This stir bar has a length of 127mm (5 inch), making it suitable for larger flasks, beakers, or other containers that require robust stirring. A key feature is the removable pivot ring, which minimizes the contact area between the stir bar and the bottom of the vessel, thereby reducing friction and noise during stirring. This pivot ring also aids in creating a stable and powerful vortex for thorough mixing. 

This stir bar is an essential tool for chemists and researchers, ensuring uniform mixing of solutions for a wide range of applications.
