IKA C-MAG HS 7 digital Heating Magnetic Stirrer

Overview

The IKA C-MAG HS 7 digital is a high-performance heating magnetic stirrer engineered for precision thermal and mechanical control in demanding laboratory environments. Designed around a robust Couette-flow stirring principle, it combines a high-torque brushless motor with a thermally stable ceramic heating plate to deliver consistent agitation and uniform heat distribution across volumes up to 10 L of aqueous media. Its core architecture integrates closed-loop temperature regulation via an integrated PT1000 resistance thermometer input—enabling direct feedback from the reaction medium rather than relying solely on plate surface sensing. This design significantly improves thermal fidelity, particularly in applications requiring narrow process windows, such as catalyst screening, polymer dissolution, or buffer equilibration under GLP-compliant workflows.

Key Features

• Chemically inert, seamless ceramic heating plate (180 × 180 mm) resistant to aggressive solvents, acids, and bases—ensuring long-term durability and ease of decontamination.
• Dual-line LCD display simultaneously shows setpoint and real-time medium temperature (when PT1000 sensor is connected), with resolution of 0.1 K and accuracy of ±0.5 K under calibrated conditions.
• Three operational modes: Standard (free parameter adjustment), Safety (prevents accidental setting changes), and Lock (full keypad immobilization for unattended operation).
• Intelligent thermal safety system featuring dual redundancy: programmable overtemperature cut-off at 550 °C and dynamic thermal runaway detection with error-code reporting (e.g., E1 = sensor fault, E2 = overheating).
• Elevated control panel geometry minimizes liquid ingress risk during vigorous stirring or accidental splashing—critical for compliance with ISO 13485 cleanroom-adjacent handling protocols.
• PT1000 interface supports traceable temperature validation; compatible with external calibration-grade probes for audit-ready documentation per FDA 21 CFR Part 11 requirements when paired with compliant data acquisition software.

Sample Compatibility & Compliance

The C-MAG HS 7 digital accommodates standard laboratory glassware (e.g., beakers, flasks, crystallization dishes) up to 10 L volume using magnetic stir bars up to 80 mm in length. Its ceramic surface tolerates contact with common organic solvents (acetone, ethanol, THF), diluted mineral acids (HCl, HNO₃ ≤ 30%), and alkaline solutions (NaOH ≤ 1 M). The unit conforms to DIN EN 60529 (IP21 ingress protection), IEC 61010-1 (safety requirements for electrical equipment), and CE marking directives for laboratory instrumentation. It supports installation in ISO Class 7/8 environments when operated within specified ambient conditions (5–40 °C, ≤80% RH, non-condensing).

Software & Data Management

While the C-MAG HS 7 digital operates as a standalone instrument, its analog PT1000 output and digital status signals (via optional IKA Labworldsoft interface module) enable integration into centralized lab monitoring systems. When connected to validated data logging platforms, temperature and speed parameters can be recorded with time-stamped audit trails, supporting 21 CFR Part 11 electronic record integrity requirements. All error codes are retained in non-volatile memory for post-event diagnostics—a feature essential for root-cause analysis in QA/QC investigations.

Applications

This instrument is routinely deployed in pharmaceutical formulation development (e.g., excipient solubilization studies), chemical synthesis (Grignard reactions, esterifications), materials science (nanoparticle dispersion stability testing), and environmental analytics (digestion protocol standardization per EPA Method 3050B). Its precise thermal ramping (5 K/min) and stable plateau maintenance make it suitable for kinetic studies where temperature-dependent reaction rates must be isolated from mechanical variability.

FAQ

Can the C-MAG HS 7 digital be used with non-aqueous solvents?

Yes—its ceramic plate and sealed electronics permit safe operation with most common organic solvents, provided vapor concentrations remain below flashpoint thresholds and ventilation standards (e.g., OSHA PELs) are observed.
Is PT1000 sensor calibration traceable to national standards?

The instrument accepts any PT1000 probe meeting DIN EN 60751 Class A tolerance; users must validate probe calibration independently using NIST-traceable reference baths prior to GxP-critical use.
Does the device support remote control or Ethernet connectivity?

No native Ethernet or Wi-Fi interface is included; however, RS232 or USB-to-serial adapters (sold separately) enable basic command-line control and data streaming via IKA’s Labworldsoft suite.
What maintenance is required to ensure long-term accuracy?

Annual verification of temperature uniformity across the plate (using multi-point IR thermography or embedded probe arrays) and periodic cleaning of the ceramic surface with neutral detergent are recommended per IKA Service Bulletin SB-HS7-2023.
How does the safety lock mode function during unattended operation?

In Lock mode, all front-panel inputs—including rotary speed dial and temperature keypad—are disabled; only emergency stop (via physical button press) remains active, satisfying ISO 14118 requirements for guarded operation.
