IKA Oven 125 control – dry Drying Oven

Overview

The IKA Oven 125 control – dry is a precision-engineered forced-convection drying oven designed for demanding laboratory and industrial applications requiring thermal stability, repeatability, and operational safety. Based on the principles of dynamic air circulation and high-efficiency thermal insulation, this oven maintains uniform temperature distribution across its 125 L stainless steel chamber—critical for drying, heat treatment, aging studies, sterilization validation, and pre-conditioning of samples in accordance with ISO, ASTM, and DIN standards. Its operating range spans from ambient +5 °C to 300 °C, with a documented temperature uniformity of ±0.3 K under steady-state conditions—a specification validated per DIN 12880 and aligned with GLP-compliant thermal mapping requirements. The unit’s robust architecture includes double-walled construction with mineral wool insulation, minimizing energy consumption while ensuring low external surface temperatures and reduced environmental heat emission.

Key Features

• Forced-air convection system with rear-mounted, brushless DC fan and adjustable airflow baffle—ensuring rapid thermal equilibration and minimal vertical/horizontal gradients.
• Dual high-resolution TFT displays provide simultaneous readout of setpoint, actual chamber temperature, elapsed time, remaining time, and safety limit status.
• Independent, user-configurable overtemperature safety circuit (TWB compliant, DIN 12880), adjustable from 50 to 320 °C—operating independently of the main controller to safeguard samples and instrumentation.
• Door-integrated microswitch automatically deactivates the circulation fan upon opening, enhancing operator safety and preventing thermal shock to sensitive materials.
• Integrated USB port enables direct logging of temperature profiles, timestamps, and alarm events onto standard USB flash drives—supporting audit-ready data retention without external software.
• RS232 interface supports serial communication for remote monitoring, integration into LIMS environments, or automated calibration verification workflows.
• Chamber constructed from electropolished AISI 304 stainless steel—resistant to corrosion, easy to clean, and compatible with solvent-based or high-humidity protocols.
• Illuminated interior with LED lighting facilitates visual inspection without compromising thermal integrity.

Sample Compatibility & Compliance

The Oven 125 control – dry accommodates a broad spectrum of sample types—including powders, granules, polymers, pharmaceutical tablets, electronic components, and coated substrates—across research, QC/QA, and production support settings. Its 550 × 525 × 450 mm usable chamber volume allows stacking of up to six load-bearing shelves (30 kg capacity each), accommodating standardized DIN/ISO test trays and custom fixtures. The unit complies with EN 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and meets the mechanical and thermal safety provisions of DIN 12880 for laboratory ovens. Optional external Pt100 probe input enables direct sample-core temperature monitoring—essential for process validation per FDA 21 CFR Part 11 and EU Annex 15 guidelines. All firmware and data logging functions are designed to support ALCOA+ data integrity principles.

Software & Data Management

While the oven operates autonomously via its embedded controller, its USB and RS232 interfaces enable seamless traceability integration. Temperature profiles—including ramp/soak segments, deviation alerts, and safety limit triggers—are timestamped and stored in CSV format for post-analysis in Excel or statistical process control (SPC) platforms. The dual-display interface supports user-defined profiles with up to 10 programmable steps, delay start functionality, and password-protected parameter modification—meeting basic requirements for controlled document management in GMP environments. No proprietary software installation is required; raw log files are human-readable and compatible with third-party validation tools used in regulated laboratories.

Applications

• Moisture content determination (e.g., gravimetric loss-on-drying per USP , ASTM D229, ISO 758).
• Thermal aging of plastics and elastomers (ASTM D573, ISO 188).
• Drying of filter papers, crucibles, and glassware prior to gravimetric analysis.
• Pre-heating and conditioning of reference standards and calibration artifacts.
• Stability testing of active pharmaceutical ingredients (APIs) and excipients under ICH Q1A(R3) conditions.
• Curing of adhesives, coatings, and composite laminates in materials science labs.
• Residual solvent removal in analytical sample preparation workflows.

FAQ

What is the maximum recommended continuous operating temperature?
The oven is rated for continuous operation at 300 °C. For extended use above 250 °C, periodic verification of door gasket integrity and fan performance is advised.
Can the oven be validated for IQ/OQ/PQ protocols?
Yes—its stable thermal performance, independent safety circuit, and digital data logging capability support full qualification per ISO/IEC 17025 and GxP requirements.
Is the USB data export function compliant with 21 CFR Part 11?
The device provides electronic records with time stamps and event logs; however, full Part 11 compliance requires implementation of site-specific access controls, audit trails, and electronic signatures at the system level—not embedded in the oven itself.
How is temperature uniformity verified during commissioning?
Uniformity assessment follows ISO 17025-accredited procedures using ≥9 calibrated Pt100 sensors placed across the working volume, per DIN 12880 Annex B.
Does the oven support nitrogen purging or inert atmosphere operation?
No—this model lacks gas inlet/outlet ports or pressure-rated seals; for inert atmosphere applications, consider IKA’s Oven 125 control – inert variant.
