Product information "IKA RCT basic Synthesis Solution 250 Magnetic Stirrer Complete Package, Aluminium Set-up Plate, 0010016490"
A glass flask is not very forgiving if, when boiling under reflux, 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 °C. 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. Stir bars 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 °C; one litre of water heats up by 9 Kelvin per minute in heating stage H1500. The safety circuit can be set independently of the setpoint between 50 and 360 °C, 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.
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 plate surface exceeds 50 °C, 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 run small batches up to 250 millilitres, this set will suffice. If your batches regularly reach 500 or 1,000 millilitres, the corresponding larger sets are the more obvious choice.
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
