Heidolph Hei-Plate Sensor Advanced Core Pack, magnetic stirrer with heating and Pt1000, 145 mm, 506-21151-00

The Heidolph Hei-Plate Sensor Advanced Package Core represents a mechatronically sophisticated and thermodynamically optimised system solution for high-precision stirring, mixing and controlled temperature control of liquid media in everyday laboratory work. Designed as a complete, turnkey set, this package combines the robust, premium Hei-PLATE Mix 'n' Heat Core magnetic stirrer with an intelligent external sensor control system. For sensitive chemical syntheses, biological temperature-control processes or demanding experimental series in research and industry, the precise interplay between mechanical stirring force and error-free heat transfer is the primary criterion for working in a way that is gentle on materials, contamination-free and process-reliable.

Excellent heat transfer via the Kera-Disk heating surface

The materials science basis of the heating plate is founded on the innovative Heidolph Kera-Disk technology, with a diameter of 145 mm. The base plate consists of a highly conductive aluminium alloy, which ensures extremely short heat-up times and a completely homogeneous temperature distribution across the entire surface area. To guarantee uncompromising chemical resistance to highly corrosive acids, alkalis and solvents, the aluminium is sealed with a non-porous, scratch-resistant ceramic coating. This hybrid construction also facilitates residue-free cleaning and protects the mechanical integrity of the heating surface during demanding continuous use.

Precise media temperature control via Pt1000 sensor

A key process engineering feature of the Sensor Advanced package is direct thermodynamic monitoring within the sample medium. The Pt1000 temperature sensor, included as standard, measures the transient actual temperature directly in the liquid and transmits this data in real time to the magnetic stirrer’s microprocessor control unit. The system thereby prevents the dreaded overshoot of the target temperature, as frequently occurs with pure heating plate controls without an external sensor. Sensitive sample components, organic phases or cell biology preparations are thus reliably protected against thermal degradation.

Hermetically sealed housing and uncompromising occupational safety

The long-term durability of the unit is ensured by a hermetically sealed die-cast aluminium housing. This structural barrier reliably protects the internal electronic and mechanical components of the drive unit (protection class IP 42) against the ingress of spilled liquids, corrosive vapours or dust. A comprehensive range of safety peripherals ensures maximum occupational safety in multi-user operation: two independent safety circuits immediately switch off the heating function in the event of an unexpected over-temperature, whilst a visual residual heat indicator reliably warns laboratory staff of the risk of burns even after the unit has been switched off.

Customised requirements & accessories

To ensure you get the most out of the Heidolph Advanced package, we stock a comprehensive range of compatible system accessories. For safe working with round-bottom flasks, we offer double-walled oil bath attachments as well as the innovative, heat-efficient Heat-On attachments made of aluminium, which completely eliminate the need for a traditional oil bath. To protect the stirrer housing from stubborn dirt, we stock precisely fitting silicone protective covers. For mechanical mixing requirements, we also offer a wide range of PTFE-coated magnetic stirring bars in various shapes (e.g. cylindrical, triangular or with a central ring). Please make use of our technical procurement service to design your measuring station to suit your specific needs.
