Safe Heating and Mixing
The Heidolph magnetic stirrers of the MR-series are perfectly suitable for smooth to intense mixing and heating of low-viscosity fluids. The Heidolph hot plate stirrer is your first choice for decomposing organic and inorganic substances. 
Aspects such as safety, convenience and cost savings have been considerably taken into account during the development of the stirrers. This is reflected in various unique product advantages of our lab hot plates. The KeraDisk hot plates allow for immediate heat transfer resulting in quick heat up times and chemically resistant surface.
The sealed housing protects your magnetic stirrer from aggressive fumes, liquids and vapors to prevent internal corrosion. The extended heating capacity of 800 W of our lab mixer reduces heat up times by 35% compared to other lab mixers at 600 W.
Turn your hot plate stirrer with our attachments into an efficiency increasing reaction station for up to 45 samples. The Heat-On attachments for our Heidolph stirrer are by far the safest, fastest and most efficient method for heating and mixing solutions in round bottom flasks.
Reduce your costs of ownership by choosing our laboratory hot plates!
You can rely on safe heating and mixing by taking advantage of our magnetic hotplate!
Choose between different models of our hot plate magnetic stirrers: MR Hei-Standard, MR Hei-Tec, MR Hei-End. Regardless of your application - our stirring hot plates will guarantee gentle stirring in biology and microbiology applications.

Magnetic Stirrers with heating
MR Mei-Standard
Model for standard applications without temperature sensor

• For your protection an independent safety circuit will switch off heating if hotplate temperature exceeds 25 °C over set temperature

• Analog knobs allow for convenient speed setting from 100 to 1,400 rpm at an accuracy of ±2 % and temperature setting up to 300 °C

• A separate on/off switch for heating prevents an unintentional heat-up. If heating is switched on the on/off button is illuminated for visual control

MR Hei-Tec
Model for higher requirements with temperature sensor

• This unit features a digital display and allows for the easy setting and monitoring of values in the illuminated readout

• For your protection an independent safety circuit will switch off heating if hotplate temperature exceeds 25 °C over set temperature

• Digital speed setting from 100 to 1,400 rpm at an accuracy of ±2 % and temperature setting up to 300 °C

• An illuminated button indicates clearly if the stirring mode is activated

• A separate on/off switch for heating prevents an unintentional heat-up. If heating is switched on the on/off button is illuminated for visual control

• Upgrade this magnetic stirrer with the optional Pt 1000 temperature sensor for precise temperature control, overshoot protection and reproducible results

MR Hei-End
Model for highest safety,

• An independent safety circuit switches off heating at an operator-programmed temperature value above your set temperature

• An additional operational safety step is required to change parameters which prevents unwanted changes to the actual setting

• The digital display allows for easy setting and monitoring of values on the illuminated readout. Speed setting from 30 to 1,400 rpm at an accuracy of ±1 % and temperature setting up to 300 °C

• Hotplate residual heat indicator in the digital display illuminates when unit is turned off and hotplate temperature is above 50 °C to prevent accidental operator injury

• To protect your sample from overheating a safety circuit switches off heating if the temperature sensor is not immersed in your media vessel

• A separate on/off switch for heating prevents an unintentional heat up. If heating is switched on the on/off button is illuminated for visual control

• Upgrade this magnetic stirrer with the optional Pt 1000 temperature sensor for precise temperature control, overshoot protection and reproducible results

Magnetic Stirrers without heating
