Magnetic Stirring Bars
Coated with PTFE, these stirring bars are corrosion and chemical resistant. Some are available in different colors for easy identification.
Octagonal stirring bars are the most commonly used shape. They have a large surface area to generate more turbulence than round bars, so they stir up particles for better mixing.
Rod stirring bars spin more smoothly than octagonal bars.
Polygonal stirring bars spin smoothly like round bars, but also generate turbulence for mixing particles, such as salts, into solutions. Select the large ODs for jobs in drums or tanks.
Capsule stirring bars are sized just right for small containers, such as vials, tubes, and gradient makers.
Oval stirring bars work best with round-bottom flasks.
Triangular stirring bars are designed to fit small vials. Use the 3/16” wide bars for 1 mL vials and the 3/8” wide bars for 3-5 mL vials.

Magnetic Stirring Bar Retrievers
Fish stirring bars out of containers using the magnetic end of these retrievers. All are corrosion and chemical resistant.
Flexible retrievers can reach into corners.
Rigid retrievers can also be used as stirring rods.
