The Yamato MFD-810 is the international-voltage twin of the MFD-800 — a strong (high-capacity) magnetic stirrer for chemical-synthesis work, stir-only (no heating), rated to move up to 20 L of water-equivalent load at 50–1600 rpm. A neodymium magnet driven by a DC brushless motor keeps stirring even when the flask is lifted off the plate. The MFD-810 is electrically the higher-voltage build; the MFD-800 is the 115V twin at the same list price.
Voltage note: The Yamato spec table (BRO-MFD-112024) lists the MFD-810 as 230V, 0.15A. The internal product name for this SKU reads 220V. Confirm the exact supply voltage (220V vs 230V) with Yamato at order.

Application Profile
- Chemical-synthesis stirring — the primary design intent; strong magnetic coupling for demanding synthesis reactions.
- Large-volume mixing — up to a 20 L water-equivalent load, well beyond a typical benchtop stir plate.
- Oil-bath synthesis — the brochure recommends pairing with Yamato BOG / BOS Series oil baths, which seat on the plate to resist slipping under vibration (oil bath sold separately).
- Continuous / elevated-vessel stirring — strong coupling maintains stir even when the flask is raised off the plate.
- Corrosion-exposed benches — the ceramic-coated die-cast aluminum plate resists chemical spill and vapor.
Note: the MFD-810 is stir-only. For combined stir + heat, see the MFH-800/810 (magnetic stirrer with hot plate).
Design Architecture
A 31 W DC brushless motor drives a neodymium magnet beneath a ø135 mm ceramic-coated die-cast aluminum plate, delivering 50–1600 rpm in 10 rpm steps with a white-LED digital display. The unit offers five rotation modes — constant speed, step-out (detachment) detection, intermittent, auto-reverse, and slow-up.
Safety is handled by an overcurrent fuse and the stirrer-detachment detection function. The operating environment is rated 4–40 °C (the MFD has no heater). At 2.8 kg and W165 x D275 mm it is a compact bench unit despite its 20 L / 30 kg load rating.
Frequently Asked Questions
How large a load can the MFD-810 stir? Up to a 20 L water-equivalent load (30 kg or less standard load capacity) at 50–1600 rpm — well beyond a typical benchtop stir plate.
Does the MFD-810 heat? No. It is a strong magnetic stirrer, stir-only. For combined stir + heat, use the MFH-800/810 (magnetic stirrer with hot plate).
What drives the stirring? A 31 W DC brushless motor turning a neodymium magnet under a ø135 mm ceramic-coated die-cast aluminum plate, with five rotation modes (constant speed, step-out detection, intermittent, auto-reverse, slow-up).
Can it be paired with an oil bath? Yes. Yamato recommends pairing with BOG / BOS Series oil baths, which seat on the plate to resist slipping under vibration (oil bath sold separately).
What voltage is the MFD-810? The higher-voltage build — the brochure spec table lists 230V, 0.15A while the product name reads 220V; confirm the exact supply voltage at order. The MFD-800 is the 115V twin.
