Strong Magnetic Stirrer With Hot Plate, 50 To 1600 rpm Overview
The Strong Magnetic Stirrer With Hot Plate, 50 To 1600 rpm (Yamato Scientific MFH800) is a compact bench stirrer in the Stirrers category, rated to a 20 L (H₂O) stirring capacity and a temperature range of RT +25°C to 310°C. Powerful magnetic coupling keeps liquids agitating even when the flask separates from the plate. LabSupplies.com stocks this unit as an authorized dealer.
A Ø135 mm aluminum die-cast plate with ceramic coating delivers even heat across the stir surface. Heating runs on a 600 W mica heater governed by PID control and a PT100 sensor, while a 31 W DC brushless motor drives the magnetic field. Glass-filled polyphenylene sulfide resin forms the housing, and a stainless steel plate handles chemical exposure.
Rated for 115V, 6A, 50/60 Hz operation, the MFH800 occupies a 165 × 275 × 90 mm footprint and weighs 3 kg. Manufactured in Japan, the stirrer is produced under ISO 9001:2015 and ISO 14001:2015 certified systems. Facilities on 220V power should order the MFH810.
Key Features
- Strong magnetic force: Continuous stirring is maintained even when the flask is lifted off the plate, with stirrer-detachment detection to flag lost coupling.
- Wide speed range: Variable 50 to 1600 rpm in 10 rpm increments, driven by a 31 W DC brushless motor.
- Precise heating: RT +25°C to 310°C in 1°C increments via a 600 W mica heater, PID control, and a PT100 sensor.
- Temperature accuracy: ±1.5°C at 100°C with the internal sensor and ±1.0°C at 50°C with an external sensor.
- Multiple rotation modes: Constant speed, step-out detection, intermittent, auto-reverse, and slow-up support varied protocols.
- Ceramic-coated plate: Ø135 mm aluminum die-cast surface pairs with BOG and BOS Series oil baths for oil-less synthesis setups.
How to Choose the Right Stirrer
Selecting a hot-plate magnetic stirrer means matching heating power and stir performance to your synthesis or sample-prep workload. Weigh these axes before ordering.
- Stirring capacity: Match the rated volume to your largest vessel — this unit handles up to 20 L of water and a 30 kg plate load.
- Temperature range: Confirm your protocol fits RT +25°C to 310°C, since oil-less aluminum block synthesis often needs the upper range.
- Control accuracy: PID control with a PT100 sensor holds ±1.5°C at 100°C, which matters for temperature-sensitive reactions.
- Voltage: Specify 115V (MFH800) or 220V (MFH810) to match your facility's power supply.
- Footprint: Verify bench space for the 165 × 275 × 90 mm chassis in crowded layouts and fume hoods.
- Safety features: Stirrer-detachment detection and multiple rotation modes protect long unattended runs.

Frequently Asked Questions
What is the temperature range of the MFH800?
The MFH800 heats from RT +25°C up to 310°C in 1°C increments, controlled by a PID system with a PT100 sensor. Accuracy is ±1.5°C at 100°C using the internal sensor and ±1.0°C at 50°C with an external sensor.
How much liquid can this stirrer handle?
Maximum stirring capacity is 20 L of water. The unit measures 165 × 275 × 90 mm and supports a plate load capacity of 30 kg or less, paired with a Ø135 mm stirring surface.
What power supply does the MFH800 require?
The MFH800 runs on 115V, 6A, 50/60 Hz, supplying a 600 W mica heater and a 31 W DC brushless motor. Facilities on 220V power should order the MFH810 instead.
What materials contact the sample?
The stirring plate is Ø135 mm aluminum die-cast with a ceramic coating, combined with a stainless steel plate surface. Exterior housing uses glass-filled polyphenylene sulfide resin, and the heat insulator is a chemically bonded glass-fiber structure.
What is the difference between the MFH800 and MFH810?
Voltage is the only difference: the MFH800 operates at 115V and the MFH810 at 220V. Both models share identical 50–1600 rpm speed, 20 L capacity, and RT +25°C to 310°C heating performance.
Can it keep stirring when the flask is lifted off the plate?
Yes. Strong magnetic force maintains stirring even when the flask separates from the plate, and stirrer-detachment detection alerts operators if coupling is lost. Rotation modes include constant speed, step-out detection, intermittent, auto-reverse, and slow-up.
