IKA C-Mag HS 7 control Heating Magnetic Stirrer

Overview

The IKA C-Mag HS 7 control is a high-performance heating magnetic stirrer engineered for precision, safety, and long-term reliability in demanding laboratory environments. Designed around a monolithic ceramic-glass square heating plate (180 × 180 mm), the unit combines robust thermal management with exceptional chemical resistance—critical for applications involving aggressive solvents, acids, or alkaline media. Its operating principle relies on permanent magnet coupling between the internal drive motor and an external stirring bar, enabling contactless torque transmission while maintaining full containment of reaction vessels. The integrated heating system delivers up to 1000 W of power, supporting rapid thermal ramping (up to 5 K/min with 1 L water) and stable temperature maintenance across a broad range from ambient to 500 °C. Unlike conventional analog stirrers, the C-Mag HS 7 control embeds digital intelligence—including real-time firmware upgradability, dual LCD displays for setpoint/actual values (speed and temperature), and IKA SmartTemp® technology—which continuously monitors surface temperature and dynamically adjusts power output to prevent overheating and ensure reproducible thermal profiles.

Key Features

• Ceramic-glass heating plate with superior chemical inertness and mechanical durability—resistant to thermal shock and corrosion from common lab reagents.
• Intelligent temperature control architecture featuring three independent measurement modes: plate-sensor (±5 K accuracy at 100 °C), external PT1000 probe (±0.5 K), and high-precision ETS-D6 sensor (±0.2 K under standardized conditions).
• Adjustable safety temperature circuit (100–650 °C) with automatic cut-off, compliant with GLP-aligned operational safeguards.
• Automatic reverse rotation and intermittent stirring mode—enhancing homogenization of viscous or heterogeneous samples and reducing vortex-induced splashing.
• Dual-display LCD interface showing both set and actual speed (50–1500 rpm, ±2% deviation at nominal load) and temperature values; resolution of 1 K for medium temperature, 5 K for plate.
• Stir bar detection (Error 5) and jump detection logic to prevent uncontrolled operation due to misalignment or loss of magnetic coupling.
• RS232 and USB interfaces for instrument connectivity, remote parameter configuration, and audit-trail-capable data logging—supporting integration into regulated workflows aligned with FDA 21 CFR Part 11 requirements when paired with validated software platforms.

Sample Compatibility & Compliance

The C-Mag HS 7 control accommodates standard laboratory glassware up to 20 L capacity (water-equivalent), compatible with stirring bars ranging from 30 mm to 80 mm in length. Its ceramic-glass surface supports flat-bottomed beakers, round-bottom flasks (with appropriate stands), and custom reaction vessels—provided magnetic coupling remains effective. The device conforms to DIN EN 60529 (IP21 ingress protection), ensuring operational integrity in typical laboratory humidity (≤80% RH) and ambient temperature (5–40 °C) conditions. All electrical components meet CE marking requirements for electromagnetic compatibility (EMC) and low-voltage directives. While not intrinsically rated for hazardous area use, its design minimizes spark risk and thermal runaway potential—making it suitable for non-explosive organic synthesis, buffer preparation, dissolution testing, and QC/QA sample conditioning per ISO/IEC 17025 guidelines.

Software & Data Management

Firmware updates are delivered via USB or RS232, enabling continuous performance optimization and feature enhancements without hardware modification. The device supports bidirectional communication for real-time parameter readback (e.g., current speed, plate temperature, error codes) and command-driven control (start/stop, setpoint adjustment, timer activation). When connected to IKA Labworldsoft™ or third-party LIMS-compatible systems, logged data—including timestamps, setpoints, deviations, and safety events—can be exported in CSV or XML format. Audit trails record user-initiated changes, firmware versions, and calibration-related actions, facilitating compliance with GMP/GLP documentation standards. No onboard memory or program storage is provided; all sequence logic resides externally—reinforcing data sovereignty and traceability.

Applications

• Controlled-temperature synthesis of metal-organic frameworks (MOFs) and coordination polymers requiring extended heating (>300 °C) and precise agitation.
• Buffer and media preparation in biopharmaceutical labs where batch-to-batch consistency demands tight thermal and rotational repeatability.
• Dissolution testing per USP , particularly for high-melting-point APIs requiring elevated bath temperatures.
• Pre-analytical sample conditioning prior to ICP-MS, HPLC, or titration—ensuring homogeneous dispersion and thermal equilibration.
• Teaching laboratories performing kinetic studies, where intermittent stirring and reversible rotation support pedagogical demonstration of mixing dynamics.

FAQ

Does the C-Mag HS 7 control support external temperature feedback control?
Yes—it accepts PT1000, ETS-D5, and ETS-D6 probes for closed-loop medium temperature regulation with sub-Kelvin accuracy under defined test conditions.
What is the maximum recommended vessel height for optimal stirring efficiency?
For consistent torque transfer and vortex control, vessels should not exceed 300 mm in height when using an 80 mm stirring bar at speeds above 800 rpm.
Is the lifetime warranty transferable between institutions?
The lifetime warranty applies to the original end-user purchaser and requires registration with IKA within 30 days of installation; transfer requires formal authorization and validation of continued compliance with operating specifications.
Can the device operate without an external temperature sensor?
Yes—the unit functions in plate-temperature mode using its built-in sensor, though medium temperature accuracy is reduced compared to external probe configurations.
How does SmartTemp® differ from conventional overtemperature protection?
SmartTemp® continuously correlates surface temperature rise rate, ambient conditions, and power input to predict thermal overshoot and preemptively modulate output—whereas standard cut-offs respond only after threshold violation.
