IKA RET basic magnetic stirrer with heating, stainless steel base, 0025008265

The IKA RET basic magnetic stirrer with heating (MPN 0025008265) represents a mechatronically high-performance, mechanically unrivalled in terms of robustness, and thermodynamically precise system solution for the simultaneous stirring, intensive mixing and precise temperature control of liquid media. Designed for a stirring volume of up to 20 litres of water, this core B2B instrument combines proven durability with sophisticated safety features. In modern laboratories specialising in chemical synthesis, pharmaceuticals and industrial process engineering, the absolutely reliable handling of viscous or high-volume batches is the decisive factor in ensuring reproducible reaction conditions with process reliability.

Excellent thermal conductivity thanks to a pure stainless steel base

A key material-specific feature of the RET basic is its high-performance heating surface, with a diameter of 135 mm, which is manufactured from a specialised, high-purity stainless steel alloy. Compared to conventionally coated surfaces, the uncoated stainless steel plate offers exceptionally high thermal conductivity, resulting in extremely short heating cycles and highly efficient heat transfer to the sample. The surface is also characterised by outstanding mechanical impact resistance, scratch resistance and excellent resistance to a wide range of aggressive solvents. The circular geometry is perfectly suited to standardised laboratory vessels, can be cleaned without leaving any residue and ensures gentle, continuous use over many years.

Precise metrology and microprocessor-controlled kinetics

From a process engineering perspective, the RET basic offers an outstanding operating and control structure for everyday laboratory use. The integrated, clear digital display enables real-time monitoring of setpoint and actual values for speed and temperature. The powerful magnetic drive is based on an electronically commutated motor, which covers a continuously variable speed range from 50 to 1,700 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 instrument features an integrated interface for the direct connection of an optional PT1000 temperature sensor system.

Hermetic seal for uncompromising laboratory safety

The structural resilience of the RET 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, dust or corrosive vapours. A multi-stage safety concept protects users and the laboratory workstation: a safety circuit, which can be adjusted independently of the main processor, 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.
