What is a magnetic stirrer used for?

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

What size vessels can typically be used with this type of stirrer?

For a heavy-duty stirrer with a 300mm x 300mm plate, it is typically suitable for use with beakers, flasks, and other vessels up to 30 litres in capacity, depending on the liquid's viscosity.

Is this unit suitable for continuous operation?

Many laboratory-grade magnetic stirrers are designed for continuous or extended operation, but buyers should confirm the specific duty cycle with the seller for this particular unit.

What maintenance is typically required for a magnetic stirrer?

Maintenance is generally minimal, primarily involving keeping the stirring plate clean and ensuring the power cord is in good condition. Periodic checks for motor noise or vibration are also advisable.

Can this stirrer handle viscous liquids?

Heavy-duty magnetic stirrers are designed to handle more viscous liquids than standard models, but performance will depend on the specific liquid's viscosity and the stir bar used. Buyers should consult the seller for suitability with highly viscous materials.
