What is the primary function of a standard magnetic stirrer?

Its primary function is to provide consistent, hands-free mixing of liquids using a rotating magnetic field to drive a stir bar within a vessel.

Can this unit be used for viscous liquids?

While it can handle some viscosity, its effectiveness decreases with highly viscous liquids. For very thick solutions, a more powerful overhead stirrer might be required.

What type of vessels are compatible with this stirrer?

It is compatible with most laboratory glassware, such as beakers, flasks, and bottles, provided they are made of non-magnetic material and can accommodate a stir bar.

Does this stirrer include a heating function?

A 'Standard Magnetic Stirrer' typically refers to a unit solely for agitation without heating. Buyers should confirm with the seller if heating is a requirement.

What maintenance is typically required for a magnetic stirrer?

Maintenance is generally minimal, involving regular cleaning of the top plate and ensuring the power cord is in good condition. No internal user-serviceable parts are typically present.
