Magnetic Stirrer MR5

The MR series magnetic stirrer is suitable for liquid or solid-liquid mixture. It can be stirred or heated/stirred at the same time to provide strong mixing and precise temperature control.


  • The heating plate is made of aluminum alloy with ceramic coating which combines chemical resistance and excellent heat conduction and distribution
  • Real-time measurement of viscosity trends, easy to observe the experiment progress
  • Stirring direction clockwise / counter-clockwise alternatively, especially for crystallization experiment
  • Intermittent operation mode can be set to satisfied the special mixing requirements
