Shape choice depends on the vessel and the fluid’s viscosity — please refer to our stirbar selection guide HERE.

Spin-out happens when the drive magnet turns faster than the stir bar can follow — usually from too high a speed setting, a bar that is undersized for the vessel, or a viscous sample. Reduce the speed, let the bar re-couple, then ramp back up gradually.

Yes. Spinbar® stir bars are fully autoclavable and encapsulated in FDA Grade, USP Class VI Teflon® PTFE for superior chemical compatibility.

The Stirring & Mixing range covers magnetic stirbars, stirbar accessories, non-magnetic stirring tools, and mechanical mixers and stirrers — from single-sample benchtop work through to high-volume drum agitation.
