IKA C-MAG HP7 Electric Heating Plate

Overview

The IKA C-MAG HP7 Electric Heating Plate is a high-performance, microprocessor-controlled laboratory heating platform engineered for precision thermal management in demanding sample preparation and digestion workflows. Designed and manufactured in Germany, it integrates resistive ceramic heating technology with closed-loop temperature feedback to deliver stable, repeatable heating across its full 180 × 180 mm ceramic surface. Unlike basic hotplates, the C-MAG HP7 employs dual-mode thermal regulation: direct plate temperature control (via integrated sensors) and optional external medium temperature control (when paired with the ETSD5 contact thermometer), enabling users to maintain solution temperature within ±3 K—critical for applications requiring strict thermal reproducibility, such as acid digestion, solvent evaporation, or pre-drying of gravimetric samples. Its robust IP21-rated enclosure, elevated control panel, and auto-shutdown at 550 °C comply with IEC 61000-6-3 (EMC) and EN 61010-1 safety standards for laboratory electrical equipment.

Key Features

• 1000 W high-power ceramic heating element delivering rapid thermal response—achieves 5 K/min heating rate in 1 L water (H15 vessel)
• Seamless, chemically inert Al₂O₃ ceramic plate (180 × 180 mm) resistant to strong acids, bases, and organic solvents per DIN ISO 17872
• LED digital display with intuitive push-button interface for precise setpoint entry (range: 50–500 °C) and real-time temperature readout
• Microprocessor-based PID control with active feedback from both plate and optional external probe (ETSD5-compatible), ensuring thermal stability of ±3 K under load
• Elevated control panel design minimizes risk of liquid ingress and improves ergonomics during prolonged operation
• Thermal warning indicator (flashing LED) alerts users to surface temperatures exceeding safe touch thresholds
• Overtemperature cutoff at 550 °C provides hardware-level protection against thermal runaway
• Universal voltage compatibility (100/120/230 V, 50/60 Hz) with input power rating of 1005 W

Sample Compatibility & Compliance

The C-MAG HP7 accommodates standard laboratory vessels including borosilicate glass beakers (up to 3 L capacity), PTFE digestion cups, quartz crucibles, and stainless steel sample pans. Its uniform heating profile (±10 °C across the active zone) supports ASTM D5291 (ash content determination), EPA Method 3050B (acid digestion of sediments), and ISO 11466 (trace metal extraction from soils). The device meets EN 61010-1:2010 for electrical safety in laboratory environments and carries CE marking for conformity with EU Low Voltage and EMC directives. Its IP21 ingress protection rating ensures operational integrity in typical lab conditions (5–40 °C ambient, ≤80% RH, non-condensing).

Software & Data Management

While the C-MAG HP7 operates as a standalone analog/digital hybrid instrument without embedded data logging, it supports GLP-compliant workflow integration via its ETSD5 sensor interface. When connected to an external calibrated PT100 probe and paired with IKA’s Labworldsoft™ (v4.0+), users can record time-stamped temperature profiles, generate audit trails, and export CSV files for regulatory reporting. All manual setpoints and shutdown events are retained in non-volatile memory. The system adheres to FDA 21 CFR Part 11 principles when used with validated third-party data acquisition platforms supporting electronic signatures and user access controls.

Applications

• Controlled-temperature acid digestion (HNO₃/HF/HClO₄ mixtures) prior to ICP-MS or AAS analysis
• Pre-concentration of aqueous environmental samples (e.g., wastewater, leachates) under regulated evaporation protocols
• Thermal conditioning of calibration standards and reference materials in QC/QA laboratories
• Heating reaction mixtures in synthetic chemistry where solvent reflux must be avoided
• Drying and ashing of filter papers and biological matrices per AOAC 990.17 and ISO 11465
• Pre-heating of GC vials and HPLC autosampler trays to minimize condensation artifacts

FAQ

Does the C-MAG HP7 support external temperature feedback control?
Yes—it features a dedicated ETSD5 interface for connecting a contact thermometer, enabling medium-temperature control with ±3 K accuracy.
Is the ceramic plate replaceable if damaged?
No—the Al₂O₃ plate is permanently bonded to the heating element; replacement requires factory service.
Can this unit be used in fume hoods?
Yes, provided ambient temperature remains within 5–40 °C and airflow does not exceed 0.5 m/s directly over the plate surface.
What is the recommended calibration interval?
IKA recommends annual verification using a NIST-traceable thermocouple and reference thermometer per ISO/IEC 17025 guidelines.
Does it meet GMP requirements for pharmaceutical labs?
When integrated with validated data capture systems and operated under documented SOPs, it fulfills Annex 11 and USP instrument qualification criteria for Category B equipment.
