This magnetic stir bar assortment provides a versatile, ready-to-use selection of PTFE-coated stir bars designed to support a wide range of laboratory mixing applications. The set includes a balanced mix of octagon stir bars with pivot rings, polygon stir bars without pivot rings, and egg-shaped stir bars with blunt edges, allowing users to match geometry to vessel type, volume, and viscosity.

PTFE coating delivers broad chemical resistance and easy cleaning, while the internal magnets provide consistent coupling and stable rotation across standard laboratory hot plate stirrers. Octagon bars with pivot rings help reduce friction and improve centering in larger vessels, while polygon and egg-shaped options offer flexibility for smaller volumes or irregular mixing conditions.

This assortment is well suited for labs standardizing workflows, equipping multiple workstations, or maintaining a reliable inventory of commonly used sizes and styles
