Milwaukee MI0040 Magnetic Stirrer | Lab-Grade 100–1000 RPM Bench & Portable Meter Stirrer
Milwaukee MI0040 Magnetic Stirrer – Precision Mixing for Lab-Grade pH & DO Measurements
Accurate pH and dissolved oxygen readings demand a homogeneous, well-mixed sample. The Milwaukee MI0040 Magnetic Stirrer delivers consistent, regulated stirring from 100 to 1000 RPM — ensuring faster sensor response times and more reliable results every time.
Compact, Chemical-Resistant Design
Ultra-compact footprint: 5.39" diameter × 2" height — fits any bench or portable meter setup
ABS plastic housing resists common laboratory chemicals
Rubber foot grips prevent slipping on wet or smooth surfaces
Round-edge design for safe, easy handling
Optical Speed Control — A Feature Most Stirrers Lack
The MI0040 uses an optical feedback mechanism to maintain your preset speed regardless of viscosity changes or load removal. When the load is suddenly lifted, the built-in speed limiter shuts down the VCO (voltage-controlled oscillator) — preventing dangerous motor over-acceleration. This level of protection is rarely found in conventional stirrers.
Speed range: 100–1000 RPM , adjustable via front-panel dial
Automatic speed correction for viscosity changes or beaker/flask removal
Stirring capacity: up to 1 liter (0.26 gallons)
Safety & Power Features
LED power indicator on front panel — always know when the unit is live
Fuse protected : replaceable 400 mA / 250V fuse for added safety
115 VAC attached power cord — plug-and-play ready
