What Is a Hotplate Magnetic Stirrer?

A hotplate magnetic stirrer is an electrically powered device that integrates a heating plate with a magnetic stirring mechanism. A magnetic stir bar placed inside the container rotates in response to a magnet beneath the plate, enabling contact-free mixing while heating.

Hotplate magnetic stirrers are commonly used for:

• Simultaneous Heating & Stirring – Achieve uniform heat distribution and consistent mixing.

• Chemical Reactions – Support exothermic/endothermic reactions requiring agitation.

• Dissolution & Homogenization – Dissolve solutes, mix reagents, and prepare solutions.

• Evaporation & Concentration – Speed up solvent removal through continuous stirring.

• Sample Preparation – Blend, warm, and condition samples efficiently.
