The IKA RET basic magnetic stirrer with heating (MPN 0025008265) combines a heating power of 800 watts with a compact housing measuring 160 x 200 x 100 millimetres and integrated Wi-Fi and LAN interfaces. The aluminium base ensures rapid, direct heat transfer to the sample. For B2B laboratory environments with high safety and documentation requirements, the RET basic combines a fast heating rate, precise speed control and a comprehensive, standards-compliant safety concept for continuous daily use.
Compact design with high power density and direct heat transfer
The 135-millimetre heating surface is made of an aluminium alloy without any additional coating, thereby enabling particularly direct heat transfer with heating rates of up to 9 Kelvin per minute whilst maintaining uniform temperature distribution; this can be adjusted across four heating speed settings. Unlike the RET basic anodised version, there is no additional oxide layer protection against scratches and chemicals; instead, the bare metal surface transfers heat without the low resistance of a coating. Despite the high heating power of 800 watts, the housing remains ultra-compact at 160 x 200 x 100 millimetres. The stirrer therefore saves space in the fume cupboard, can be positioned on any standard laboratory lifting platform and is suitable for parallel experimental set-ups in confined spaces.
Networked laboratory processes via Wi-Fi and LAN
For integration into networked laboratory infrastructures and automated documentation processes, the RET basic is equipped as standard with Wi-Fi and LAN interfaces, as well as the wired USB-C and RS232 interfaces. This connectivity allows the magnetic stirrer to be monitored centrally, controlled remotely or integrated into higher-level software solutions, including via the IKA app. The communication interface, which is based on ASCII-based Namur commands, also enables direct device-to-device communication. For example, the RET basic can be linked to an IKA overhead stirrer: if the stirring speed of the viscous medium falls below a critical threshold, the RET basic automatically deactivates the heating. This is an important prerequisite for reliable, unattended continuous operation.
Comprehensive safety concept in accordance with EN IEC 61010-2-010
With a total of 18 integrated safety features, the RET basic complies with the laboratory equipment standard EN IEC 61010-2-010 for heated laboratory equipment. System safety is further confirmed by a certificate from TÜV Süd in accordance with the NRTL standard (comparable to UL and CSA). In addition to a mechanically adjustable safety range (50 to 360 degrees Celsius) via two separate plate sensors, the unit features Delta-T medium monitoring, sensor breakage and misalignment detection, as well as automatic heating shutdown in the event of a sudden drop in temperature, such as that caused by glass breakage. In the event of a safety shutdown, the ‘Always-Stir’ function takes effect: heating stops whilst stirring remains active to prevent delayed boiling or hotspots in the medium. A visual residual heat warning provides additional protection against burns on surfaces exceeding 50 degrees Celsius.
Typical applications
The combination of network connectivity, direct heat transfer and a comprehensive safety concept makes the RET basic a versatile device for digitised laboratory environments:
- Networked laboratory processes requiring documentation, thanks to integrated Wi-Fi and LAN interfaces

Matching temperature sensors
The IKA ETS-D5 is an electronic contact thermometer with a PT1000 sensor and touchscreen display for external temperature control on compatible IKA magnetic stirrers with heating. Once connected, it takes over active temperature control within the medium and switches the heating of the connected magnetic stirrer on and off as required, whilst the magnetic stirrer itself remains active as an additional safety monitoring device. The replaceable PT1000 sensor, tolerance class A, covers a measuring range from -20 °C to +400 °C with a resolution of 0.1 K. Three control modes (Fast, Precise, Synthesis Block-optimised) adapt the heating rate to different applications. Integrated safety functions such as sensor timeout and temperature drop detection automatically switch off the heater in the event of a fault. The housing is dust- and splash-proof to IP 54. Suitable for The IKA RCT basic magnetic stirrer with heating (MPN 0025008259) is confirmed to be compatible: Its own connection specification states that external temperature sensors of types PT1000, ETS-D5 and ETS-D6 are supported via a socket in accordance with DIN 12878.

The IKA ETS-D7 Wireless Sensor (MPN 0025008370) is a wireless temperature sensor, which transmits measured values wirelessly to compatible IKA magnetic stirrers and agitators, thereby eliminating the need for cumbersome cable connections in the fume cupboard or glovebox. Temperature data can be sent in real time to the paired drive unit via a digital WPAN radio link with a range of up to 15 metres, allowing the stirrer and sensor to be positioned independently of one another. Thanks to an integrated BNC socket, the ETS-D7 also functions as a stand-alone pH meter as soon as a suitable pH electrode is connected, thereby covering two measurement tasks with a single device. For networked laboratory workstations where temperature and stirring parameters are to be documented centrally, this wireless solution also reduces the amount of cabling required at the workstation. All-in-one measurement technology: temperature and pH in a single device An analogue pH electrode can be connected directly to the ETS-D7 via the integrated BNC socket. This transforms the wireless sensor into a fully-fledged, portable pH meter, eliminating the need to purchase an additional device for occasional pH checks. The TFT touchscreen displays temperature and pH values with a resolution of two decimal places (0.01) each; the accuracy of the pH measurement is ±0.1 pH over a measuring range of 0 to 14 pH. The touchscreen interface allows you to switch between displays and adjust settings directly on the device. For laboratories that only need to check pH values occasionally, this eliminates the need to purchase a separate pH metre. The temperature probe’s minimum immersion depth of 20 mm also allows measurements to be taken in smaller sample vessels. Intelligent energy management with Auto-Wake An integrated infrared and brightness sensor detects whether people are in the immediate vicinity and automatically activates the display when necessary (Auto-Wake). When idle, the sensor automatically switches to standby mode, achieving a battery life of up to 100 hours in Auto-Wake mode. With the display switched on continuously, the operating time is up to 50 hours. The integrated battery, with a capacity of 700 mAh at 5 V, reaches around 50 per cent of its full capacity after 60 minutes and around 75 per cent after 90 minutes, meaning that even short charging breaks can be utilised for continued use. For long test series lasting several days, this energy management system significantly reduces the effort required for recharging. Suitable for IKA RET basic, RCT basic and Eurostar control The ETS-D7 transmits its measured values via WPAN radio to compatible IKA drives. These include the magnetic stirrers of the RET basic and RCT basic series, as well as the Eurostar control stirrers. For older RCT basic models without an integrated WPAN module, the wireless connection can be retrofitted using a separately available USB wireless receiver. Depending on the connected drive, temperature and stirring parameters can be adjusted directly via the sensor’s touchscreen interface using bidirectional communication. In addition, the ETS-D7 can be integrated into safety control loops as a second, redundant temperature sensor, providing an independent control mechanism in the event of exothermic reactions. For laboratories already using a RET basic magnetic stirrer, the ETS-D7 can thus be used as a wireless extension of the existing temperature control system. Bidirectional networking for process documentation Full compatibility with the labworldsoft laboratory software enables the digital recording, central control and documentation of recorded temperature and pH curves. For laboratories that need to document their measurement series in an audit-compliant manner, the ETS-D7 can thus be integrated into existing digital quality management processes, rather than recording measurement values manually. This ensures that the assignment of measurement values remains traceable even when test series are running in parallel across multiple workstations. Typical applications Its wireless design and dual function as a temperature and pH meter make the ETS-D7 a versatile tool in a variety of laboratory situations: Temperature monitoring during syntheses with reflux cooling, without intrusive cables in the fume cupboardCable-free measurements in the glovebox, where signal cables would restrict handlingpH monitoring directly at the reaction vessel via the integrated BNC interfaceRedundant temperature monitoring in safety-critical, exothermic reactionsDocumentation of temperature and pH curves via labworldsoft in a networked laboratoryRetrofitting older RCT basic magnetic stirrers with wireless temperature controlMobile use as a stand-alone pH meter, independent of the connected stirrer Technical details Sensor typePT1000 (DIN IEC 751 Class A), replaceable Replaceable temperature sensorStandard component H62.51 Temperature measurement range-20 °C to +400 °C (in combination with H62 sensor) Temperature measurement resolution0.01 K Temperature measurement accuracy±0.05 K plus the tolerance of the PT1000 sensor Minimum immersion depth20 mm pH measurement functionVia integrated BNC socket (female) pH measurement range0 to 14 pH pH resolution0.01 pH pH accuracy±0.1 pH Display technologyTFT touchscreen Proximity sensorsInfrared and brightness detection for auto-wake AlertsStatus LED and audible alert function Wireless interfaceWPAN Communication rangeUp to 15 metres (depending on the building structure) Wired interfaceUSB-C Power supplyBuilt-in, rechargeable battery Battery capacity700 mAh, 5 V Maximum charging current500 mA Operating time (display on continuously)Up to 50 hours Operating time (Auto-Wake mode)Up to 100 hours Charging rate50% capacity in 60 minutes, 75% capacity in 90 minutes Dimensions (W x D x H)52 x 385 x 40 mm Net weight0.125 kg Protection class according to DIN EN 60529IP 54 Permissible ambient temperature+5 to +40 °C Permissible relative humidityUp to 80 % Scope of delivery 1 x IKA ETS-D7 Wireless Sensor main unit (MPN 0025008370)1 x Replaceable temperature probe H62.511 x Integrated lithium-ion battery (700 mAh)1 x Quick Start Guide / Safety Guide A pH electrode and a USB-C charging adapter are not included and are available separately.

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.

IKA IKAFLON round magnetic stirring bars are PTFE-coated stirring cores with a round cross-section for use on IKA magnetic stirrers. The PTFE coating is chemically resistant to most common laboratory solvents and acids and cleans without residue, which makes the bars practical when switching between different batches.The series is available in five lengths from 15 to 50 mm, each in a pack of 5, so a suitably sized stirring core can be chosen for different vessel sizes and fill volumes, avoiding a bar that is too small spinning erratically in a large vessel or one that is too large getting stuck at the vessel base.CompatibilityThe IKAFLON 15 round is official accessory for the IKA RCT basic anodised magnetic stirrer with heating (MPN 0020133785), RET basic magnetic stirrer with heating (MPN 0025008265), RET basic anodised magnetic stirrer with heating (MPN 0020133787) and RH lite magnetic stirrer with heating (MPN 0020007108).
