What is a magnetic stirrer used for?

A magnetic stirrer is used to mix liquids by creating a rotating magnetic field that causes a stir bar immersed in the liquid to spin. This provides efficient and consistent agitation without direct contact.

What is the 'Speedsafe™' mechanism?

Speedsafe™ is a safety feature designed to prevent the stirrer from dangerously overspeeding if the stir bar is suddenly removed from the solution. It monitors and limits the motor speed.

Can this stirrer handle viscous liquids?

While compact stirrers can handle a range of viscosities, their effectiveness with highly viscous liquids may be limited. Buyers should consult the seller for specific performance data for this unit.

Is a stir bar included with the unit?

Stir bars are typically separate consumables. Buyers should confirm with the seller whether a stir bar is included with this specific used unit.

What maintenance is required for a magnetic stirrer?

Maintenance is generally minimal, involving cleaning of the stirring surface and occasional inspection of the power cord. The durable housing is designed to resist chemical spills.
