Product information "IKA RCT basic Synthesis Solution 250 Magnetic Stirrer Complete Pack, Aluminium Base Plate, 0010016490"
A glass flask is not very forgiving if, during reflux distillation, a sensor cable rubs against the clamp or if an oil bath spills onto the hotplate should the flask break. The IKA RCT basic Synthesis Solution 250 (ID No. 0010016490) addresses both issues: a wireless temperature sensor measures directly within the reaction medium, a second, wired sensor simultaneously monitors the synthesis block, and the flask is housed in an aluminium block rather than in an open oil bath. IKA supplies the complete set for round-bottom flasks up to 250 millilitres: the RCT basic magnetic stirrer with heating, flask holder, PT wireless and PT1000 sensors, USB dongle, as well as a stand and clamps for securing the flask.
Wireless temperature and pH measurement in the reaction medium
The centrepiece of the set is the PT wireless sensor, which transmits measurement values wirelessly to the RCT basic. A pH electrode can also be connected via the PT wireless’s BNC socket; the RCT basic’s display then shows the pH value directly, without the need for a separate measuring device. As there is no longer a sensor cable leading to the flask, the setup on the stand remains more flexible, and there is no risk of cables being damaged or scorched by contact with the heating plate. The supplied USB WD dongle also connects the RCT basic wirelessly to the IKA Lab Assistant app for visualising the measurement data.
Dual temperature monitoring for greater safety
In addition to the PT wireless, the set includes the wired PT 1000.60 sensor. Both sensors measure simultaneously, but at different locations: the PT 1000.60 monitors and limits the temperature at the synthesis block or heat transfer medium, whilst the PT wireless measures the temperature directly within the reaction medium. The RCT basic displays both values side by side on the screen. This separate measurement is particularly important in the event of glass breakage, as a sudden discrepancy between the block temperature and the medium temperature becomes immediately apparent and does not have to be detected via a single measurement point.
Synthesis block instead of an oil bath
The flask holder supplied (IKA designation H 135.25, for 250 ml round-bottom flasks, without handle) is a synthesis block made of solid anodised aluminium and is temperature-resistant up to 300 degrees Celsius. Compared to an oil or sand bath, this significantly reduces the potential for hazards and simplifies handling and cleaning, as there is no risk of an oil bath leaking or sand becoming stuck. A universal clamp (R 350) additionally secures the flask to the stand. The RCT basic has a second stand mount, which can be used to attach an additional stand rod for a reflux condenser if required.
RCT basic as a basic unit: stirring and heating with 800 watts
The basic unit covers a speed range of 50 to 1,500 revolutions per minute, adjusted via a rotary-push control with an accuracy of 10 revolutions per minute. Stirring rods with lengths of 20 to 80 millimetres can be used; according to the data sheet, the stirring capacity is up to 20 litres of water, and the maximum load is 25 kilograms. The heater has an output of 800 watts and reaches temperatures ranging from room temperature to 310 degrees Celsius; one litre of water heats up by 9 Kelvin per minute in heating stage H1500. The safety limit can be set independently of the setpoint between 50 and 360 degrees Celsius – a control logic that IKA has been using for decades in heated equipment. The die-cast aluminium housing is rated to IP 54, which protects against splashing water and corrosive laboratory air.
Safety concept for unattended operation
Beneath the heating plate are two further, separate temperature sensors: one controls the setpoint temperature, whilst the second monitors an independently adjustable safety limit in accordance with EN IEC 61010-2-010; this setting is adjusted mechanically directly on the unit and is independent of the process setpoint. If the medium temperature drops suddenly – for example, due to glass breakage or the medium evaporating – the RCT basic detects this and can switch off the heating. If the temperature fails to rise despite the power supply – for example, because a sensor is not immersed in the medium – the device also deactivates the heating automatically. A visual warning is also displayed as soon as the mounting surface exceeds 50 degrees Celsius, even if the unit is already switched off.
Differences compared to the larger sets in the series
The Synthesis Solution 250 shares the base unit with the 500 and 1,000 millilitre sets; the flask holder in all three sets is tailored to the respective flask volume. If you mainly carry out small experiments up to 250 millilitres, this set will suffice. If your experiments regularly reach 500 or 1,000 millilitres, the corresponding larger sets are the more obvious choice. It has not been verified at this stage whether the 500 and 1000 millilitre sets include the same range of wireless sensors as the 250-ml set; the shop descriptions for these sets to date only mention the wired PT1000 probe.
Typical applications
As a synthesis kit with wireless sensor technology, the RCT basic Synthesis Solution 250 is suitable for, amongst other things:
- Organic syntheses on a 250-ml scale with simultaneous monitoring of block and medium temperatures
- Refluxing, where an additional stand rod is required for the condenser
- pH monitoring directly in the reaction mixture, without a separate pH meter at the workstation
- Laboratory workstations that wish to avoid open oil baths for safety or cleaning reasons

The new IKA ETS-D5 electronic contact thermometer (MPN 0025008371) completely redefines precision, safety and ease of use in laboratory thermal analysis. Developed as a high-performance mechatronic control unit for demanding laboratory processes, this instrument takes over active, direct temperature control of the medium once connected. It controls the heating power of a coupled magnetic stirrer by intelligently switching the heating plate on and off, whilst the stirrer itself acts as a redundant monitoring unit for the preset safety limits. The ETS-D5 thus transforms any compatible workstation into a future-proof, high-precision control centre for reproducible experimental series. Integrated safety architecture for risk-free processes From a process engineering perspective, the ETS-D5 offers a comprehensive range of sophisticated protective functions that contribute significantly to laboratory safety and risk minimisation. The system features an adjustable sensor timeout, which is triggered immediately if the probe is inadvertently outside the liquid medium. Precise temperature drop detection reacts dynamically to unexpected thermal gradients, whilst setpoint monitoring (Delta T) immediately stops temperature control if the target value is exceeded by a critical margin. To prevent operator errors in multi-user operation, the maximum settable temperature can be strictly limited via a setpoint limit. In the event of a transient fault, the heating circuit remains permanently switched off to protect personnel and the sample matrix. Optimised PID control and application-specific modes The instrument’s control technology ensures absolutely stable temperature control without thermal overshoot. Coupled with a high-precision, interchangeable PT1000 temperature sensor of tolerance class A, the system covers a wide operating range from –20 °C to +400 °C. Three application-specific temperature control modes ensure maximum flexibility in day-to-day laboratory work: ‘Fast’ for ultra-fast heating cycles, ‘Precise’ for working at the minimum tolerance limit, and a specialised synthesis block mode that is perfectly tailored to the thermodynamic requirements of chemical syntheses. For highly sensitive organic or biological sample structures, the heating rate can also be precisely reduced in percentage increments. Ergonomic touch-screen control concept and documentation The instrument’s exterior breaks away from complicated analogue designs and features a user-friendly, clear touchscreen display for intuitive parameter configuration during continuous operation. The almost completely enclosed system reliably protects the internal electronic components from aggressive vapours and liquids in the harsh everyday laboratory environment. A future-proof, integrated USB-C interface also enables the rapid, error-free export of all transient measurement data to a PC, thereby ensuring seamless documentation, validation and traceability of your processes in accordance with modern GLP standards.

The IKA ETS-D7 Wireless Sensor (MPN 0025008370) is a highly innovative, mechatronic, high-end wireless system solution for the simultaneous thermal and electrochemical analysis of samples in the modern laboratory. Far more than a conventional measuring transducer, this wireless instrument functions as an intelligent sensor and control centre. It transmits transient temperature data via digital radio transmission (WPAN) over a distance of up to 15 metres to compatible IKA drives, such as the magnetic stirrers of the RET basic and RCT basic series or the Eurostar control stirrers. This technological decoupling completely eliminates disruptive signal cables in the fume cupboard or glovebox and takes occupational safety and mechanical flexibility to a new level. All-in-one dual measurement technology with integrated BNC interface An outstanding technical feature of the ETS-D7 is its versatile configuration as a self-contained, stand-alone measuring device. The compact module features an integrated BNC socket, to which an analogue pH electrode can be connected directly. This transforms the temperature sensor into a fully-fledged, portable pH meter without the need for costly additional investment. The integrated, high-contrast TFT touchscreen displays both the temperature readings and the transient pH value with a fine metrological resolution of two decimal places (0.01). This guarantees absolutely error-free and precise readability of all process parameters directly at the physical measurement site. Smart sensor technology and highly efficient energy management The wireless sensor’s electronic system architecture stands out thanks to its forward-looking, software-controlled energy management. Using integrated infrared and ambient light sensors, the device automatically detects whether laboratory staff are in the immediate vicinity to read the measurements. The display only activates when actually needed (Auto-Wake) and automatically switches to a deep standby mode when idle, thereby achieving a remarkable battery life of up to 100 hours. For test series requiring continuous visual monitoring, continuous display operation can be flexibly enabled. Bidirectional connectivity for seamless Industry 4.0 validation Thanks to a sophisticated bidirectional communication matrix, the ETS-D7 enables full synchronisation of setpoint and actual values in a networked laboratory. Depending on the connected main unit, adjustments to temperature and stirring parameters can be made directly via the sensor’s touch interface. Furthermore, the sensor can be integrated as a second, redundant temperature sensor into critical safety control loops to reliably prevent exothermic incidents. Full compatibility with the labworldsoft (LWS) laboratory software ensures seamless digital recording, centralised control and audit-compliant documentation of all transient measurement curves in accordance with modern quality management standards.

The IKA Pt.Wireless wireless sensor (MPN 0025008369) represents a technologically pioneering, highly optimised mechatronic system solution for seamless digital temperature and electrochemical sample analysis in the laboratory. Designed as an intelligent, fully wireless sensor, this instrument eliminates the need for cumbersome cable routing in fume cupboards, gloveboxes or on crowded laboratory workstations. Via digital radio transmission (WPAN), the system transmits transient measurement data in real time over a range of up to 15 metres to compatible IKA system components – such as the latest generations of the RCT basic and RET basic magnetic stirrer series, Eurostar control stirrers, and directly to the labworldsoft (LWS) laboratory equipment software. Full app integration and display-free efficiency Unlike traditional measuring instruments, the Pt.Wireless does away with physically bulky display elements on the sensor itself and shifts all visual control to the innovative IKA app. Once paired – a straightforward process – the smartphone or tablet acts as a high-resolution dashboard for the real-time display of all parameters. Calibration of the precise temperature and pH calibration curves is also carried out error-free directly via the app’s user interface. For electrochemical analysis, the slim module features an integrated BNC interface to which an analogue pH electrode can be connected directly. This transforms the system into an ultra-compact all-in-one solution for monitoring complex reaction media. Intelligent LED status monitoring for weekend operation The Pt.Wireless’s key technical feature is its predictive, multi-stage energy management system, which enables a continuous operating time of up to 150 hours. To reliably prevent unforeseen system failures during critical long-term experiments, the sensor features a smart battery status warning via an integrated LED indicator. If the remaining runtime of the lithium battery falls below 70 hours, the LED signals at an early stage that safe, unattended operation over a full weekend can no longer be guaranteed. When the remaining runtime falls below a critical reserve of approximately 20 hours, the indicator changes to a slowly flashing yellow warning signal to alert laboratory staff that safe overnight operation is about to cease.
