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 (flea) immersed in the liquid to spin. This provides efficient and consistent mixing without direct contact.

Does this unit include a heating function?

The Heidolph MR 3000 series often includes a heating function. Buyers should contact the seller to confirm if this specific unit is equipped with heating and its operational range.

What kind of vessels can be used with this stirrer?

Typically, any laboratory vessel made of non-magnetic material, such as glass beakers, flasks, or bottles, can be used, provided it fits on the stirring plate and is compatible with the stir bar.

Is this unit suitable for continuous operation?

Heidolph equipment is generally designed for robust laboratory use, and units of this type are commonly suitable for extended periods of operation. However, specific duty cycles should be confirmed with the seller.

What maintenance is required for a magnetic stirrer?

Maintenance is typically minimal, involving regular cleaning of the stirring plate and ensuring the power cord is in good condition. No specific internal maintenance is usually required by the user.
