Magnetic Stir Bar Large Size, Stirbars/Stir Bars, PTFE Stirrer/Mixer Bar. Spinbar Teflon Octagon Magnetic Stirring Bar, 4 Pack, 50mm / 1.96 Inch

• Large Size Value Set: Includes 4 pieces of large magnetic stir bars, each measuring 50mm (1.96 inches) in length. This size is ideal for stirring larger volumes of solutions and helps you find the perfect fit for specific containers and liquid viscosities.
• Premium PTFE Material: Encased in high-quality PTFE (Teflon) coating, known for its chemical inertness. It resists corrosive chemicals, withstands high temperatures, and offers a non-stick, easy-to-clean surface with excellent insulation properties.
• Octagonal Design with Pivot Ring: Features an octagonal shape with a central integral pivot ring. This design minimizes the contact area with the container bottom to reduce friction, ensuring smooth, stable rotation and preventing wobbling during operation.
• Versatile Applications: perfectly suited for scientific research in chemistry and biology labs, as well as home use. It is widely used for mixing yeast starters in home brewing, creating tinctures, or blending various solutions.
• Durable & High Performance: precise assembly with a strong magnetic core ensures a secure coupling with the magnetic stirrer. These bars are wear-resistant, non-toxic, and designed to generate a strong, consistent stirring vortex.
