IKA myPlate, magnetic stirrer without heating, customisable glass surface, 0025005156

Electromagnetic Rotational Kinematics and Fluid Mechanics

The homogeneous mixing of aqueous or low-viscosity matrices on a laboratory scale requires a compact, high-frequency power transmission system. The IKA myPlate operates as a purely electromagnetic stirrer (without a thermodynamic heating unit) and is designed for a hydrodynamic working capacity of up to 1.5 L (based on water). The brushless drive generates a continuously variable rotating magnetic field that synchronises the rotor in the reaction vessel at a frequency of 0 to 2,500 revolutions per minute. This asymmetrically wide speed range creates a massive axial flow vortex. The resulting centrifugal forces and shear stresses maximise molecular mass transfer (mixing kinetics) and completely eliminate fluid dynamic dead zones in the beaker or Erlenmeyer flask.

Amorphous glass matrix and optical system architecture

The materials science architecture of the large mounting surface (Ø 135 mm) is based on a monolithic layer of tempered real glass. This amorphous silicate structure guarantees absolute inertness towards highly aggressive chemical reagents, strong acids or alkalis, which would irreversibly corrode conventional plastic housings in the event of a spill. A distinctive feature of this chassis’s design is the integrated, tool-free removable insert frame. This allows the instrument’s surface to be visually customised by inserting individual printed media, without blocking the magnetic field lines or compromising the metrological enclosure. As the system is thermodynamically decoupled, thermal denaturation of thermolabile samples is physically impossible.

Metrological cybernetics and capacitive interface control

The mechanical drive train is implemented via an electronically commutated motor (EC motor). The absence of mechanical sliding contacts eliminates tribological wear, reduces power consumption to a minimum of 4 W and qualifies the system for continuous operation without thermal stress. Metrological control of the process is carried out via a capacitive sensor keypad (touch slider) and a digital LED display. The integrated sensor technology translates the manual swiping gesture instantly into an incremental adjustment of the rotational speed and provides seamless visual feedback on the rotational kinematics.

Important note: Magnetic stirring rods for hydrodynamic energy transfer into the fluid are essential for operation and are not included in the scope of delivery! Due to the magnetic pole spacing within the chassis, only stirring rods with a maximum length of 30 mm may be used to prevent asymmetric flow separation (decoupling).

Individual requirements & accessories

The IKA myPlate generates a rotating magnetic field but, without a suitable rotor, does not induce any mechanical flow vectors. For maximum efficiency in 1.5 L beakers, we recommend using cylindrical, PTFE-coated IKAFLON magnetic stirring rods (max. 30 mm in length). To retrieve the magnetic stir bars without contamination after homogenisation, you will also need a PTFE magnetic stir bar retriever.
