Magnetic Stir Bar Kit
The Lab Safety Supply 21R586 pack contains ten cylindrical stirring bars. Each bar measures 9.52 mm in diameter and 19.05 mm in overall length. They are built for laboratory professionals who need consistent mixing in standard vessels. The white PTFE coating resists chemical attack during routine use.
Alnico V Magnet Core
An Alnico V magnet sits inside the PTFE shell to deliver strong coupling with external stirrer drives. A moulded pivot ring reduces friction against the container base for smoother rotation. The durable coating protects the magnet from corrosive reagents and simplifies cleaning between experiments.
Ten-Pack Convenience
Ten bars in one package let technicians outfit multiple workstations or keep spares on hand. Immediate replacements minimise downtime when a bar is lost or damaged. California Proposition 65 warnings apply because the product contains listed chemicals.

Questions about this item
What diameter does the 9.52 mm cylindrical stir bar require from the vessel?
The 9.52 mm diameter fits standard laboratory vessels with matching internal dimensions; the PTFE coating reduces friction against glass walls.
How much vertical clearance does the 19.05 mm overall length need above the stir plate?
The 19.05 mm length requires at least that much clear space between the vessel bottom and any overhead obstruction to rotate freely.
Does the pivot ring change the way the bar couples to the magnetic drive?
The pivot ring stabilises the Alnico V magnet during rotation, preventing the bar from migrating or tumbling at higher speeds.
