The Ward's® magnetic induction stirrer is motor-less, using advanced coil technology that produces the strongest magnetic coupling and has no moving parts making this unit 100% wear-free and maintenance free. 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.
There are several advantages that come with a motor-less magnetic stirrer versus a traditional magnetic stirrer and they include: 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 idea for use in general research, life science, industrial, quality analysis, and clinical laboratory settings.
