Product Description
Most magnetic stirrers are sized for a beaker. The Yamato MFD-810 is sized for a batch: it will couple to and turn 20 litres of water from a ø135 mm plate, and it does so with a neodymium magnet driven by a 31 W DC brushless motor rather than the small ferrite-and-AC-motor arrangement found in general-purpose units. That matters in chemical synthesis, where a viscous or loaded reaction mixture will make an ordinary stirrer's bar decouple and rattle — the point at which mixing silently stops and the reaction quietly stops being what you think it is.
The MFD is the stirring platform without the heater — the same magnet, motor, plate and control electronics, for work that needs strong agitation at ambient temperature and has no reason to pay for a hot plate. If you also need heat, the MFH-800 (115 V) and MFH-810 (220 V) are the same unit with a 600 W heated plate.
Key Features
- 20 L maximum stirring capacity (H₂O) — genuine batch-scale magnetic stirring
- 50 to 1600 rpm, set in 10 rpm increments on a white LED digital display
- Neodymium magnet with a 31 W DC brushless motor — holds coupling in viscous and loaded mixtures
- ø135 mm ceramic-coated aluminium die-cast plate, chemically resistant and easy to clean
- Step-out detection — the unit tells you when the stirring bar has decoupled instead of spinning on regardless
- Intermittent, auto-reverse and slow-up rotation modes for shear-sensitive or foaming systems
- Standard load capacity 30 kg or less on the plate
- Calibration offset and selectable power-failure recovery mode
