Rank Brothers M301 Stirrer Control Unit

Product Description:

The Rank Brothers M301 Stirrer Control Unit is a high-precision, motor-free stirring system that utilises electromagnetic fields to generate rotational movement in the attached stirring heads. With no moving parts, this system eliminates mechanical wear, reducing maintenance requirements and ensuring a longer lifespan than traditional stirrers.

This unit is specifically designed for scientific research and laboratory applications, particularly where precise and low-noise stirring is required. The M301’s advanced control system ensures uniform stirring speeds, making it highly effective for experiments requiring repeatable results.

Key Features of the Rank Brothers M301 Stirrer Control Unit

• Motor-less operation – Reduces wear and tear, ensuring long-term reliability
• Minimal heat generation – Protects temperature-sensitive samples
• Low electrical noise – Ideal for laboratories using sensitive electronic instrumentation
• High-precision stirring – Ensures uniform mixing across multiple vessels
• Multi-head control – Drive up to three stirring heads simultaneously
• Touchscreen display – Intuitive control and easy adjustments
• Four stirring modes for customisable mixing
  • • Constant speed (clockwise)
    • Constant speed (anticlockwise)
    • Automatic reversing (slow acceleration)
    • Automatic reversing (fast acceleration)
  • Start functionality – Ensures a smooth pickup of the stirring bar
  • Capture function – Helps retrieve dislodged stirring bars without adjusting speed
  • Compact design – Fits seamlessly into laboratory setups, including fume cupboards.

Advantages Over Motor-Driven Stirrers:

• • • Reduced Electrical Noise: Ideal for applications requiring sensitive electronic measurements.
    • Enhanced Reliability: Absence of moving parts leads to increased durability and reduced maintenance.
    • Consistent Performance: All connected heads operate at precisely the same speed, ensuring uniform stirring across multiple samples.
    • Minimal Heat Generation: Protects temperature-sensitive samples from excessive heat associated with motor-driven stirrers.
