IKA Oven 125 control – dry glass

Overview

The IKA Oven 125 control – dry glass is a precision-engineered forced-convection drying oven designed for reproducible thermal processing in regulated laboratory and industrial quality assurance environments. Based on the DIN 12880 standard for laboratory ovens, it employs a robust axial fan-assisted airflow system to ensure uniform heat distribution across the entire 125 L stainless-steel chamber (550 × 525 × 450 mm). Its operational temperature range spans from ambient +5 °C up to 300 °C—exceeding typical high-temperature drying requirements—while maintaining long-term stability within ±0.3 K under steady-state conditions. The double-glazed, tempered glass door enables non-intrusive visual monitoring of samples without compromising thermal integrity or triggering unnecessary cooling cycles. Integrated thermal insulation minimizes energy consumption and external surface temperatures, supporting both cost-efficient operation and compliance with ISO 50001-aligned energy management practices.

Key Features

• Forced convection heating system with rear-mounted axial fan and optimized air duct geometry for homogeneous temperature distribution (DIN 12880 compliant)
• Dual high-resolution TFT displays showing real-time setpoint, actual chamber temperature, elapsed time, and safety circuit status
• Independent safety temperature controller (TWB) with adjustable limit range (50–320 °C), fully decoupled from the main control loop per DIN EN 61000-6-2 and IEC 61000-4-3
• USB interface enabling direct data logging of temperature profiles onto removable storage media—supports traceable record retention for GLP/GMP audits
• RS232 serial port for integration into centralized lab automation systems (e.g., LIMS or SCADA platforms)
• Automatic fan shutoff upon door opening to prevent thermal shock and improve operator safety
• Illuminated interior with LED lighting and integrated cable feed-through port at rear wall for external sensor connections (e.g., Pt100 probe for sample-core temperature validation)
• Six-position stainless-steel shelf support system; each shelf rated for 30 kg load capacity and compatible with standard DIN 433-sized trays

Sample Compatibility & Compliance

The Oven 125 control – dry glass accommodates diverse sample formats including Petri dishes, weighing boats, crucibles, polymer test specimens, pharmaceutical stability batches, and moisture-content reference standards. Its stainless-steel (AISI 304) chamber resists corrosion from residual solvents, saline solutions, and acidic vapors encountered during routine drying, curing, or aging protocols. The device conforms to key international standards including DIN 12880 (laboratory ovens), EN 61010-1 (safety requirements for electrical equipment), and EN 60529 (IP20 ingress protection). Optional calibration certificates—traceable to national metrology institutes (e.g., PTB, NIST)—are available to support ISO/IEC 17025-accredited testing laboratories. All firmware and UI logic are validated for compliance with FDA 21 CFR Part 11 requirements regarding electronic records and signatures when used with appropriate audit-trail-enabled software configurations.

Software & Data Management

While the oven operates as a standalone instrument, its embedded microcontroller supports time-stamped data capture via USB mass-storage mode. Users may configure multi-step temperature ramps, hold durations (1–142,560 minutes), and delayed start functions directly through the intuitive touchscreen menu. Logged datasets include timestamped chamber temperature, setpoint, safety circuit status, and fan state—formatted as CSV files for post-processing in Excel, MATLAB, or statistical process control (SPC) tools. For networked deployment, optional IKA Labworld software provides remote monitoring, alarm notification via email/SNMP, and automated report generation aligned with ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate).

Applications

This oven serves critical roles across analytical, materials science, and quality control workflows: gravimetric moisture analysis (ASTM D2231, ISO 712), thermogravimetric pre-conditioning of composites, accelerated aging of packaging materials (ASTM F1980), residual solvent removal in API synthesis, ash content determination (AOAC 923.03), and thermal stabilization of calibration standards. Its precise thermal control and documented repeatability make it suitable for method validation studies required under USP , EP 2.2.43, and ICH Q5C guidelines.

FAQ

Does the oven support external probe input for sample-specific temperature measurement?
Yes—via the rear-mounted analog input port, users may connect a calibrated Pt100 or thermocouple sensor to monitor actual sample temperature independently of chamber air temperature.
Is the USB data logging function compliant with 21 CFR Part 11?
When deployed with IKA Labworld software and configured with user authentication, electronic signatures, and audit-trail activation, the system meets predicate rule requirements for electronic records.
What is the maximum allowable load weight inside the chamber?
The total static load capacity is 180 kg (6 shelves × 30 kg), provided weight is evenly distributed and does not obstruct airflow grilles.
Can the safety temperature controller be calibrated independently?
Yes—the TWB circuit includes dedicated calibration offset adjustment accessible only via service mode with authorized credentials.
Is maintenance documentation available in English?
Full technical manuals, spare parts catalogs, and preventive maintenance checklists are supplied in English and updated quarterly via IKA’s secure customer portal.
