IKA RCT basic Anodized Heating Magnetic Stirrer

Overview

The IKA RCT basic Anodized Heating Magnetic Stirrer is an engineered solution for precise, safe, and reproducible temperature-controlled mixing in modern laboratories. Based on the Couette flow principle, it employs a rotating magnetic field generated by a brushless EC motor to drive magnetic stir bars within vessels—enabling homogeneous dispersion, dissolution, or reaction initiation without mechanical shaft penetration. Its integrated 800 W ceramic-coated heating plate delivers rapid thermal response (up to 9 K/min in standard aqueous loads) while maintaining uniform surface temperature distribution across its Ø135 mm anodized aluminum plate. Designed for compliance with EN IEC 61010-2-010 for laboratory heating equipment, the RCT basic exceeds baseline safety requirements through redundant thermal monitoring, independent safety circuitry, and fail-safe operational logic—making it suitable for use with flammable solvents, viscous media, and unattended overnight protocols.

Key Features

• Brushless EC motor ensuring stable torque delivery up to 1500 rpm with minimal heat generation and extended service life
• Anodized ceramic-coated heating plate offering chemical resistance, scratch protection, and long-term thermal stability
• IP54-rated die-cast aluminum housing providing protection against splashes, corrosive vapors, and mechanical impact
• Compact footprint (160 × 200 × 100 mm) optimized for fume hood integration and multi-unit parallel setups
• Dual independent temperature sensing: one for process control, another for user-defined safety limit (50–360 °C), mechanically adjustable and decoupled from setpoint
• Delta-T safety function: automatic heater shutdown upon detection of unexpected medium temperature deviation
• Rapid temperature drop detection (e.g., due to vessel breakage or solvent evaporation) triggers immediate thermal cutoff
• Abnormal heating rate detection prevents operation if no temperature rise is observed post-activation
• Support for up to two external temperature sensors (wired PT1000 or wireless ETS-D7/PT) enabling differential monitoring of bath vs. sample temperature
• RS232 and USB-C interfaces compliant with NA-MUR ASCII command protocol for integration into Labworldsoft® or third-party SCADA systems
• IKA HUB compatibility enabling programmable timing, intermittent stirring, reverse rotation, and multi-device coordination (e.g., synchronized shutdown with EUROSTAR overhead stirrers)
• Customizable 14-segment LED display showing real-time values for speed, temperature, timer, pH (with ETS-D7), or user-defined parameters

Sample Compatibility & Compliance

The RCT basic accommodates standard laboratory glassware including beakers (up to 20 L capacity), round-bottom flasks, and jacketed reactors. It supports stir bars ranging from 20 to 80 mm in length and is compatible with both aqueous and organic solvent systems—including ethanol, acetone, THF, and chlorinated hydrocarbons—provided appropriate temperature limits are observed. The device meets CE marking requirements and has been independently certified by TÜV SÜD to UL/CSA-equivalent NRTL standards. Its safety architecture aligns with GLP and GMP environmental monitoring practices, supporting audit-ready operation when used with Labworldsoft® logging and IKA Lab Assistant mobile application (optional). The dual-sensor architecture satisfies FDA 21 CFR Part 11 requirements for electronic record integrity when paired with validated software configurations.

Software & Data Management

Communication via RS232 or USB-C enables bidirectional ASCII-based control using IKA Labworldsoft® v4.0 or higher. This permits remote parameter setting, real-time data acquisition (speed, temperature, timer status), event-triggered alarms, and automated report generation. All temperature and speed logs include timestamps and can be exported in CSV format for traceability. When connected to IKA HUB, users gain access to advanced features such as multi-step programs, conditional logic (e.g., “start timer after reaching 80 °C”), and cross-device interlocks. Optional wireless sensor integration (ETS-D7, PT wireless) eliminates cable clutter and reduces calibration drift risk associated with wired thermocouples. Full audit trail functionality—including operator ID assignment, change history, and electronic signature support—is available under validated deployment conditions.

Applications

The RCT basic serves critical roles across pharmaceutical QC (dissolution testing per USP , buffer preparation), polymer synthesis (viscosity-controlled monomer addition), electrochemistry (electrolyte conditioning), food science (emulsion homogenization), and environmental analysis (digestion of soil/water samples). Its high-temperature capability (up to 310 °C) supports applications such as silicone oil baths, molten salt reactions, and catalyst activation. The Delta-T and sudden cooling detection functions make it particularly valuable for exothermic reaction monitoring and distillation support. In regulated environments, its configurable safety thresholds and hardware-enforced thermal cutoffs reduce reliance on operator vigilance—enhancing consistency in method transfer and routine testing workflows.

FAQ

What is the maximum recommended volume for accurate temperature control?
For optimal thermal uniformity and response time, IKA recommends using vessels containing ≤5 L of liquid when operating above 200 °C; larger volumes (up to 20 L) are supported at lower temperatures (<100 °C) with appropriate stir bar selection.
Can the RCT basic operate without external temperature feedback?
Yes—the unit functions as a standalone hotplate/stirrer using its built-in heating plate sensor. However, for improved accuracy (±0.2 K), external PT1000 or wireless sensors are strongly advised for critical applications.
Is the device compatible with non-IKA stir bars?
It supports all standard magnetic stir bars meeting ISO 8573-1 dimensional tolerances and magnetization strength specifications; however, IKA-certified bars are recommended for full torque transmission at high speeds.
Does the RCT basic support GLP-compliant data export?
When used with Labworldsoft® under validated configuration and enabled audit trail settings, it complies with ALCOA+ principles for raw data integrity, including metadata capture, version control, and immutable log files.
How does the “continuous stirring” safety feature work during fault conditions?
Upon triggering any safety shutdown (e.g., overtemperature), the motor remains active to prevent localized boiling, bumping, or phase separation—maintaining agitation until manual intervention or system reset.
