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 Full Specifications Model MI0040 Stirring Capacity 1 Liter (0.26 gal) max Speed Range 100–1000 RPM Power Supply 115 VAC Housing Material ABS Plastic (chemical resistant) Operating Environment 32–122°F (0–50°C) / Max RH 95% Dimensions 5.39" dia × 2" H (137 × 51 mm) Weight 1.4 lbs (640 g) Country of Origin Romania UPC / Barcode 810666007530 What Lab Users Are Saying "Easy and precise speed control." | "Long-lasting motor." | "Very easy to clean at day's end." | "Does the job well."
