EMS Magnetic Induction Stirrer

Electron Microscopy Sciences is proud to introduce a motorless, advanced coil technology, stirrer to improve all of your stirring needs. It produces the strongest magnetic coupling for viscous solutions, with no moving parts, making this unit 100% wear-free and maintenance free.

Motorless Magnetic Stirrer

The magnetic coil technology works on the inductive principle with alternative current (AC) as its driving force. The generated moving magnetic field drives the spinning of the stir bar in the vessel.

Several advantages come with a motorless magnetic stirrer vs. a traditional magnetic stirrer:

  • No heat is generated after hours of continuous use making this unit ideal for temperature sensitive samples and environments
  • Quiet operation and low vibration helps users stay focused in the lab
  • The magnetic field driving the stir bar maintains continuous constant speeds for reproducible results

With advanced coil technology the strength of the coupling between the unit and stir bar is controlled by the amount of electric current that flows through the coil. The more turns of the wire making up the coil, a stronger magnetic field is produced.High-quality rare-earth magnets are used in the stirrer design to ensure a strong magnetic coupling with consistent accurate alignment which significantly reduces the chance of spin-outs.

The magnetic induction stirrer is ideal for use in general research, life science, industrial, quality analysis, and clinical laboratory settings.

Precision At the Touch of One Button

With just one convenient rotating knob select:

  • Mode – single clockwise, single counter-clockwise, or auto reverse rotation (1 to 99 cycles)
  • Speed – 10 to 2,000 rpm, variable (1 rpm increments)
  • Time – 30 seconds to 60 minutes or continuous (1 second increments)

Once a program has started, the speed, cycle and time can be monitored. The stirring speed can be adjusted while a program is running.

  • Capacity – 3 L +
  • An easy to read digital display precisely controls time (30 seconds to 60 minutes) and speed (10 to 2,000 rpm)
  • Rapid acceleration and braking
    (less than 10 seconds) to quickly meet stirring speed requirements
  • Speed remains constant, even when load changes
  • Durable ABS housing is corrosion resistant and easy to clean
  • Two stir bars included (35 mm x 12 mm) with a PTFE coating for chemical resistance
