Strong Magnetic Stirrer with Hot Plate

The Yamato MFH-810 is the international-voltage twin of the MFH-800, a strong magnetic stirrer with an integrated hot plate. It combines a high-capacity magnetic drive (up to 20 L water-equivalent load, 50–1600 rpm) with a 600 W mica heater delivering plate temperatures from RT +25 °C up to 310 °C under PID control with a PT100 sensor. Built for heated chemical-synthesis work including oil-less aluminum-block reactions. This is the 220V variant (3A); the MFH-800 is the 115V twin (6A) at the same list price.

Key Specifications

Application Profile

• Heated chemical synthesis. Controlled stir + heat to 310 °C for reactions requiring elevated temperature.
• Oil-less (aluminum-block) synthesis. The brochure highlights aluminum-block systems for oil-free heated reactions (blocks sold separately).
• Oil-bath synthesis. Pairs with Yamato BOG / BOS Series oil baths for traditional heated-bath work.
• Large-volume heated mixing. Up to a 20 L water-equivalent load with strong magnetic coupling that holds even when the flask is raised.
• Precision-temperature reactions. PID control with an external PT100 sensor tightens accuracy to ±1.0 °C at 50 °C at the sample.

For stir-only work (no heat), see the MFD-800/810.

Design Architecture

The MFH-810 stacks two subsystems in one W165 x D275 mm chassis. The stir side is a 31 W DC brushless motor driving a neodymium magnet at 50–1600 rpm with five rotation modes and step-out detection. The heat side adds a 600 W mica heater under the ceramic-coated die-cast aluminum plate, governed by PID control and a PT100 sensor to RT +25 °C … 310 °C. An included external temperature sensor lets the controller regulate to the sample (±1.0 °C @ 50 °C) rather than the plate (±1.5 °C @ 100 °C internal).

The heated design carries a fuller safety stack than the stir-only MFD: overcurrent fuse (5A internal on the -810), temperature upper-limit error, overheating prevention at a fixed temperature, and a high-temperature warning, plus a service outlet, high-limit function, power-failure recovery mode selection, and calibration offset.

Frequently Asked Questions

What temperature range does the MFH-810 reach? The MFH-810 heats from RT +25 °C up to 310 °C under PID control with a PT100 sensor, driven by a 600 W mica heater.

What is the stirring speed and capacity of the MFH-810? It stirs at 50–1600 rpm (set in 10 rpm increments) with a maximum stirring capacity of 20 L water-equivalent load, using a neodymium magnet on a 31 W DC brushless motor.

Is the MFH-810 a 115V or 220V unit? The MFH-810 is the 220V variant (3A). The MFH-800 is the 115V twin (6A) at the same list price; confirm your outlet and plug type before ordering.

Does the MFH-810 come with an external temperature sensor? Yes. Per the brochure, the unit ships with an external temperature sensor, which lets the controller regulate to the sample (±1.0 °C @ 50 °C) rather than the plate (±1.5 °C @ 100 °C internal).

Can the MFH-810 be used for stir-only work without heat? The MFH-810 combines stirring and heating. For stir-only work with no heat, Yamato offers the MFD-800/810.
