IKA RCT basic magnetic stirrer with heating, aluminium base plate, 0025008259

The IKA RCT basic magnetic stirrer with heating, in its updated version (MPN 0025005927), represents the new generation of the global laboratory standard, featuring advanced mechatronics and materials science. As the direct, technologically optimised successor to the classic RCT basic, this system combines proven reliability with advanced control functions. Designed for the simultaneous stirring and precise temperature control of liquid media up to a volume of 20 litres, this instrument is the central system component for chemical syntheses, pharmaceutical developments and demanding routine processes in the modern laboratory environment.

Superior heat transfer thanks to innovative Kera-Disk technology

The thermal foundation of the magnetic stirrer is formed by the distinctive Kera-Disk base, which has a diameter of 135 mm. The support structure consists of a highly conductive aluminium alloy, which ensures minimal heating times and absolutely homogeneous temperature distribution. To protect against aggressive media, acids, alkalis and stubborn solvents, the metal surface is sealed with a non-porous, scratch-resistant ceramic coating. This hybrid material structure combines the excellent thermal conductivity of aluminium with the extreme chemical inertness of ceramic, whilst also facilitating rapid, residue-free cleaning of the work surface.

Precise metrology and microprocessor-controlled kinetics

From a process engineering perspective, the new generation of the RCT basic offers a significantly improved operating and control structure. The integrated, high-contrast digital display enables real-time monitoring of setpoint and actual values for speed and temperature. The powerful magnetic drive covers a continuously variable speed range from 50 to 1,500 revolutions per minute and maintains the selected kinetics absolutely constant, even during transient changes in viscosity. For high-precision temperature control directly within the sample, the device features an integrated interface for the direct connection of an optional PT1000 temperature sensor.

Hermetic seal for uncompromising laboratory safety

The structural resilience of the RCT basic is underpinned by a sealed die-cast aluminium housing with IP 42 protection. This barrier reliably protects the sensitive control electronics and the motor from the ingress of spilled liquids or vapours. A multi-stage safety concept protects users and the laboratory workstation: an independently adjustable safety circuit immediately switches off the 600-watt heating element in the event of an unexpected overheating. In addition, a visual residual heat indicator (Hot Top Indicator) warns staff of the risk of burns from the heating plate until it has cooled down to a safe temperature.
