Heathrow Scientific Mini Magnetic Stirrer - 120155 Series | Compact 3L, Chemical-Resistant ABS

Not every stirring task needs a full-size instrument. When bench space is tight and the protocol is straightforward — dissolving a buffer, preparing a standard solution, running a titration — a compact, dependable mini magnetic stirrer is the right tool. The Heathrow Scientific Mini Magnetic Stirrer delivers powerful magnetic coupling in a 7.2 × 5.2 × 1.85 in footprint that takes up less space than a standard sheet of paper. Constructed from chemical-resistant ABS and polycarbonate, it handles the daily wear of general research, academic, life sciences, industrial, and clinical lab environments without fuss.

The Mini Stirrer accommodates vessels up to 3L and features a simple one-dial speed control that makes it accessible to first-time users without sacrificing the performance that experienced researchers expect. Its lightweight 1.84 lb body makes it easy to relocate between workstations, and the included universal AC adapter with 4 interchangeable plugs ensures compatibility with US, EU, UK, and international power supplies straight out of the box.

Features and Benefits

• Ultra-Compact Benchtop Footprint: At 7.2 × 5.2 × 1.85 in (18.3 × 13.2 × 4.7 cm) and 1.84 lb, this is one of the smallest full-function magnetic stirrers available — ideal for cramped benches, fume hoods, biosafety cabinets, and portable field lab setups.

• Powerful Magnetic Coupling Up to 3L: Despite its small size, the Mini Stirrer maintains strong magnetic coupling in vessels from small vials up to 3L beakers and flasks — handling the full range of routine lab mixing tasks without a larger instrument.

• Chemical-Resistant ABS & Polycarbonate Construction: The housing blend resists common lab solvents, dilute acids, and bases — protecting the instrument during accidental spills and making surface cleaning straightforward between protocols.

• Simple One-Dial Speed Control: Intuitive speed adjustment requires no programming or setup — ideal for shared labs, teaching environments, and any setting where multiple users with different experience levels operate the same instrument.

• Universal Power Supply Included: Ships with a universal 100–240VAC adapter and 4 interchangeable plug types (NA, JPN, EU, UK) — no voltage converter required for international installations or shared equipment in multi-country research programs.

• CE & UKCA Certified: Meets regulatory requirements for use in North American, European, and UK laboratory environments — supporting compliance documentation for regulated research and clinical settings.

Laboratory Applications

• Buffer & Solution Preparation: Dissolve salts, pH buffers, and chemical standards in beakers and flasks from small volumes up to 3L — the everyday workhorse task that benefits most from a dedicated, always-ready compact stirrer.

• Fume Hood & Biosafety Cabinet Use: The minimal 7.2 × 5.2 in footprint fits easily inside restricted enclosures where space is at a premium — allowing continuous stirring of volatile, hazardous, or biological samples under proper containment.

• Clinical & Point-of-Care Labs: Prepare reagent solutions, calibration standards, and assay buffers in clinical settings where a compact, low-maintenance instrument is preferred over large benchtop equipment.

• Teaching & Student Labs: Simple dial control, durable construction, and low cost make this the ideal first magnetic stirrer for undergraduate coursework, high school science labs, and shared multi-user teaching environments.

Frequently Asked Questions

What is the maximum vessel size for the Mini Magnetic Stirrer?
The Mini Stirrer maintains effective magnetic coupling in vessels up to 3 liters. For optimal coupling, use appropriately sized PTFE stir bars — larger vessels benefit from longer bars (30–35mm), while small vials perform best with 10–20mm bars.

What is the difference between 120155 (Grey/Purple) and 120595 (Grey/Blue)?
Both are functionally identical — same motor, same capacity, same certifications, same power supply. The only difference is the accent color of the housing. Choose based on lab color-coding preferences or personal preference.

Can this stirrer be used in a fume hood?
Yes. The compact 7.2 × 5.2 in footprint fits comfortably inside standard fume hoods and biosafety cabinets. The chemical-resistant ABS/PC housing tolerates incidental exposure to fumes and vapors common in enclosed laboratory enclosures.

Does the Mini Stirrer have a heating function?
No — this is a stirrer only, without a heating element. For applications requiring simultaneous heating and stirring, consider a dedicated hot plate stirrer. For stirring-only protocols including buffer preparation, titrations, and reagent dissolution, the Mini Stirrer is the right tool.
