Strong Magnetic Stirrer, 50 To 1600 rpm Overview
The Strong Magnetic Stirrer, 50 to 1600 rpm (Yamato Scientific MFD800) is a compact stirrer engineered for continuous mixing across a 50–1600 rpm range. Its strong magnetic field maintains rotation even when a flask lifts off the Ø135 mm plate. Maximum stirring capacity reaches 20 L of water, with an operating window of 4–40°C. LabSupplies.com supplies this unit as an authorized Yamato Scientific dealer.
A DC brushless motor delivers 31 W of torque through a corrosion- and chemical-resistant ceramic-coated aluminum die-cast plate. Five rotation modes — constant speed, step-out detection, intermittent, auto-reverse, and slow-up — adapt mixing to viscous or sensitive samples. Glass-filled polyphenylene sulfide resin forms the exterior, while glass-fiber heat-insulator structures shield internal components.
Built in Japan, the MFD800 measures 165 × 275 × 90 mm and weighs 2.8 kg, fitting tight bench space. Power draws 115V, 0.25A at 50/60 Hz; the MFD810 covers 220V sites. Manufacturing follows ISO 9001:2015 and ISO 14001:2015 standards. Load capacity tops out at 30 kg.
Key Features
- Strong magnetic force: continues stirring even when the flask separates from the plate.
- Wide speed range: 50–1600 rpm adjustable in 10 rpm increments.
- Five rotation modes: constant speed, step-out detection, intermittent, auto-reverse, and slow-up.
- Durable plate: Ø135 mm aluminum die-cast surface with corrosion- and chemical-resistant ceramic coating.
- Brushless motor: 31 W DC drive supporting a 30 kg load capacity and 20 L water-stirring capacity.
- System compatibility: pairs with Yamato BOG and BOS Series oil baths and supports aluminum block systems for oil-less synthesis.
How to Choose the Right Stirrer
Selecting a magnetic stirrer means matching mechanical power and control to your heaviest, most viscous workload. Review these axes before specifying a unit.
- Stirring capacity: this model handles up to 20 L of water — match it against your largest vessel volume.
- Speed range and resolution: 50–1600 rpm in 10 rpm steps suits both gentle suspensions and aggressive blending.
- Control modes: confirm that constant, intermittent, auto-reverse, and slow-up modes cover your protocol needs.
- Voltage: choose MFD800 for 115V sites or MFD810 for 220V sites to match facility power.
- Plate chemistry: a ceramic-coated aluminum surface resists corrosive spills during routine use.
- Footprint and load: 165 × 275 × 90 mm with 30 kg load capacity supports heavy bench setups in limited space.

Frequently Asked Questions
What is the operating temperature range of the MFD800?
The stirrer operates between 4°C and 40°C in 1°C increments. This window covers standard ambient laboratory conditions for synthesis and mixing work.
What is the maximum stirring capacity and how large is the unit?
Maximum stirring capacity is 20 L of water. External dimensions measure 165 × 275 × 90 mm, the stirring plate is Ø135 mm, and net weight is 2.8 kg.
What voltage and power does the stirrer require?
MFD800 runs on 115V and MFD810 runs on 220V. Power draw is 0.25A at 50/60 Hz, driving a 31 W DC brushless motor.
What materials are used in the stirring plate and housing?
The Ø135 mm plate is aluminum die-cast with a corrosion- and chemical-resistant ceramic coating. Exterior housing uses glass-filled polyphenylene sulfide resin, with glass-fiber heat-insulator structures inside.
What is the difference between the MFD800 and MFD810?
Supply voltage is the only difference: MFD800 is 115V and MFD810 is 220V. Speed range, capacity, plate, motor, and dimensions are identical across both models.
Does the stirrer keep mixing if the flask lifts off the plate?
Yes. Strong magnetic force maintains stirring even when the flask is separated from the plate, supporting oil-less synthesis with aluminum block systems and BOG/BOS Series oil baths.
