What is a magnetic stirrer used for?

A magnetic stirrer is used in laboratories to mix liquids or solutions by creating a rotating magnetic field that causes a stir bar (flea) immersed in the liquid to spin.

What does 'Speedsafe' mean on a magnetic stirrer?

The 'Speedsafe' mechanism is a safety feature that limits the maximum stirring speed, typically to 1000 rpm, even if the magnetic coupling is lost or the load is suddenly removed. This prevents potential splashing or accidents.

Can this stirrer handle viscous liquids?

This class of compact stirrer is generally designed for light-duty applications and low-viscosity liquids. For highly viscous liquids, a more powerful stirrer or overhead mixer would typically be required.

What is the typical maximum volume this unit can stir?

For this model, the maximum stirring capacity is typically stated as 1 litre. Buyers should confirm the exact capacity with the seller for this specific unit.

Is this unit suitable for continuous operation?

Many laboratory magnetic stirrers are designed for intermittent to continuous use, but it is advisable to check the manufacturer's guidelines or with the seller regarding prolonged operation for this specific used unit.
