IKA C-MAG HS 7 control Heating Magnetic Stirrer

Overview

The IKA C-MAG HS 7 control is a high-performance, microprocessor-controlled heating magnetic stirrer engineered for precision, reproducibility, and long-term operational stability in demanding laboratory environments. Designed and manufactured in Staufen, Germany, it employs Couette-type rotational mixing via rotating magnetic fields generated beneath a seamless, chemically resistant ceramic glass plate. Its integrated heating element delivers rapid, uniform thermal energy transfer—critical for temperature-sensitive reactions, solvent evaporation, crystallization studies, and kinetic investigations where simultaneous control of agitation and thermal profile is essential. Unlike conventional stirrers with metal or coated plates, the C-MAG HS 7 control’s monolithic ceramic glass surface offers exceptional resistance to strong acids, bases, and organic solvents, eliminating corrosion-induced calibration drift and ensuring consistent heat distribution across the entire 180 × 180 mm active area. The device operates on a robust architecture compliant with DIN EN 60529 (IP21), supporting continuous duty cycles under ambient conditions of 5–40 °C and ≤80% relative humidity.

Key Features

• Single-position ceramic glass heating plate (180 × 180 mm) with scratch- and chemical-resistant surface
• Adjustable speed range from 50 to 1500 rpm with ±2% speed deviation (no load, nominal voltage, 1500 rpm at 25 °C)
• Precise digital temperature control: ambient to 500 °C; resolution of 5 K on plate, 1 K in medium
• IKA SmartTemp® technology—real-time thermal monitoring with adaptive safety cutoff and predictive overtemperature mitigation
• Dual-mode temperature sensing: built-in plate sensor + external probe interface (PT1000, ETS-D5, ETS-D6)
• High-accuracy heating control: ±0.2 K with ETS-D6 probe (500 mL H₂O, 600 mL beaker, 40 mm stir bar, 600 rpm, 50 °C)
• Automatic reverse rotation and intermittent stirring mode for improved homogenization of viscous or particulate-laden samples
• Stir bar jump detection (Error 5) and real-time status feedback via dual-line LCD display (set vs. actual speed/temperature)
• Lifetime warranty backed by IKA’s ISO 9001-certified manufacturing and global service infrastructure
• RS232 and USB interfaces for firmware updates, remote parameter logging, and integration into automated lab workflows

Sample Compatibility & Compliance

The C-MAG HS 7 control accommodates standard laboratory vessels—including borosilicate glass beakers (up to 3 L capacity per vessel), stainless steel reactors, and PTFE-coated containers—compatible with stir bars ranging from 30 to 80 mm in length. Its inert ceramic glass surface ensures no leaching or catalytic interference during prolonged heating of aggressive reagents (e.g., concentrated HNO₃, NaOH, DMF, DMSO). The unit meets key regulatory expectations for analytical and quality control laboratories: its digital temperature logging capability supports GLP/GMP documentation requirements, while firmware-upgradable architecture facilitates compliance with evolving FDA 21 CFR Part 11 data integrity standards when paired with validated software. External temperature probes (ETS-D5/D6) enable traceable, medium-centered thermal validation aligned with ASTM E2251 and ISO/IEC 17025 guidelines for temperature measurement uncertainty.

Software & Data Management

Firmware updates are delivered via USB or RS232 connection using IKA’s official LabWorldSoft platform—enabling feature enhancements, bug resolution, and protocol optimization without hardware modification. The device supports time-stamped parameter export (speed, temperature, duration) in CSV format for post-acquisition analysis in MATLAB, Python, or LIMS systems. While the C-MAG HS 7 control does not embed programmable multi-step protocols or pH/graphing functions, its deterministic timer, reversible agitation logic, and error-flagged events (e.g., “Stir bar missing”, “Overtemp warning”) provide auditable operational metadata suitable for internal SOPs and external audit trails. All interface communications adhere to standard ASCII command protocols, ensuring interoperability with third-party automation controllers.

Applications

This instrument is routinely deployed in synthetic chemistry labs for reflux condensation, polymerization initiation, and catalyst screening; in pharmaceutical QC for dissolution testing preparation and buffer equilibration; in materials science for nanoparticle dispersion in high-boiling-point solvents; and in environmental labs for heavy-metal extraction and digestate homogenization prior to ICP-MS analysis. Its ability to sustain stable 500 °C plate temperatures enables solvent-free thermal decomposition studies, while SmartTemp®-guided ramping minimizes thermal shock in sensitive biological matrices such as enzyme-containing buffers or protein formulations.

FAQ

Does the C-MAG HS 7 control support external temperature feedback for closed-loop control?

Yes—it accepts PT1000, ETS-D5, and ETS-D6 probes for medium-sensing, enabling PID-based regulation with accuracy down to ±0.2 K.
What is the maximum recommended vessel size for optimal stirring performance?

For full 20 L capacity, use wide-diameter containers (e.g., ≥200 mm ID) with appropriately sized stir bars (≥60 mm); viscosity >500 mPa·s requires reduced volume or lower speed settings.
Is the lifetime warranty transferable between institutions?

The warranty applies to the original end-user registrant and requires proof of purchase and IKA product registration; institutional transfers must be formally documented with IKA Service.
Can the device operate continuously at 500 °C?

Yes—thermal stability is maintained under continuous load, though sustained operation above 400 °C is recommended only with inert atmosphere or vacuum conditions to prevent oxidation of stir bars and vessel contents.
How does SmartTemp® differ from conventional overtemperature protection?

SmartTemp® dynamically adjusts heating power based on real-time thermal gradient analysis—not just absolute temperature—thereby preventing overshoot and improving repeatability in exothermic processes.
