Stirring Bars and Rods

Combine the functions of a stirring rod and rubber policeman with Thermo Scientific™ Nalgene™ Polypropylene Stirring Rods, featuring a flat paddle at one end and a triangular paddle at the other end. These autoclavable stirring rods are chemically compatible with a wide range of lab reagents.

Provides effective stirring for use in round-bottom flasks and containers with bases that are slightly curved or uneven.

Use with containers, vessel, stirrers, and stirring hot plates. The PTFE-coated magnet stirrers are stable for many general purpose applications. The bars are cross-shaped for improved stirring action.

Particularly useful for environmental testing and life science applications in which small sample volumes need to be prepared and evaluated

Useful for high temperature applications up to 274°C (525°F)

Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape for stirring small volumes in vessels such as vials, tubes and gradient makers.

Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape for stirring small volumes in vessels such as vials, tubes and gradient makers.

The multifaceted magnetic stirring bar surface adds turbulence relative to similar size smooth cylindrical stirring bars.

Includes 16 stir bars. Fisherbrand™ Octagonal Magnetic Stir Bar Kit offers a convenient kit packed in compartmented storage box.

Provide better mixing at bottom of vessel with less splashing.

Pull stirring bars out of containers easily with a magnet.

These magnetic stirring bars are the most commonly used shape.

Designed especially for use in round-bottom vessels as they spin unrestricted by the vessel contour.

To agitate liquids in round bottom vessels where other stirring bars cannot be used.

Stir bars have polygon multifaceted surfaces that add turbulence relative to similar smooth size cylindrical bars.
