IKA Oven 125 basic dry Drying Oven

Overview

The IKA Oven 125 basic dry is a precision-engineered forced-convection drying oven designed for routine and demanding laboratory applications requiring stable thermal environments. Based on the principles of uniform air circulation and precise proportional-integral-derivative (PID) temperature control, this oven maintains exceptional thermal homogeneity across its 125 L stainless steel chamber—critical for drying, conditioning, sterilization validation, thermal aging, and stability testing in compliance with ISO 17025, ASTM E145, and DIN 12880 standards. Its robust architecture features double-wall insulation with low-emission, odorless mineral wool, minimizing heat loss and reducing energy consumption without compromising structural integrity or operator safety. The unit operates within a calibrated range from ambient +5 °C to 250 °C, with a typical temperature stability of ±0.3 K under steady-state conditions—a specification validated during factory calibration and traceable to national metrology institutes.

Key Features

• Forced-air convection system with electronically adjustable damper ensures reproducible airflow distribution and minimizes thermal gradients across the chamber volume.
• Stainless steel interior (AISI 304) provides corrosion resistance, ease of decontamination, and long-term dimensional stability under repeated thermal cycling.
• High-resolution LED display with intuitive 7-segment interface supports real-time monitoring of setpoint, actual temperature, and elapsed time.
• Programmable timer (1 min to 144,000 min) enables unattended operation and supports GLP-compliant test protocols requiring defined exposure durations.
• Dual-level safety architecture: primary PID controller plus independent mechanical overtemperature cut-off (DIN 12880 Class II), preventing thermal runaway during fault conditions.
• USB-B interface allows direct connection to a host PC for time-stamped temperature logging—compatible with standard CSV export for audit-ready data archiving and post-processing in Excel or LIMS platforms.
• Keypad lock function prevents unauthorized parameter modification, supporting lab access control policies aligned with ISO/IEC 17025 clause 6.4.10.

Sample Compatibility & Compliance

The Oven 125 basic dry accommodates a broad spectrum of sample formats—including Petri dishes, weighing boats, glassware, polymer specimens, pharmaceutical packaging materials, and electronic components—within its 550 × 525 × 450 mm working chamber. Up to six adjustable stainless steel shelves (30 kg load capacity each) support flexible configuration for heterogeneous batch processing. The unit conforms to DIN EN 60529 (IP20), EN 61010-1 (safety requirements for electrical equipment), and EU Directive 2014/30/EU (EMC). It is suitable for use in GMP-regulated environments when integrated into documented validation protocols (IQ/OQ/PQ) and operated under controlled environmental conditions (5–40 °C ambient, ≤80 % RH).

Software & Data Management

No proprietary software is required. Temperature logging via USB-B outputs timestamped ASCII-formatted data streams compatible with open-source tools (e.g., Python pandas, R) or commercial LIMS systems. Each recorded entry includes date/time, setpoint, measured chamber temperature, and operational status flags. The absence of embedded firmware-based analytics ensures deterministic behavior and simplifies 21 CFR Part 11 compliance when paired with institutional electronic signature workflows and audit-trail-enabled host systems.

Applications

• Moisture content determination (ASTM D229, ISO 712)
• Thermal aging of polymers and composites (ISO 188, ASTM D573)
• Drying of filter papers, crucibles, and analytical reagents prior to gravimetric analysis
• Pre-conditioning of samples for tensile testing, adhesion evaluation, or SEM preparation
• Stability studies of active pharmaceutical ingredients (APIs) and excipients per ICH Q1A(R2)
• Calibration of temperature-sensitive sensors and reference materials
• Post-curing of coatings and adhesives in QC laboratories

FAQ

Is the Oven 125 basic dry suitable for sterilization applications?

No—it is not certified for microbiological sterilization (e.g., steam or dry-heat sterilization per ISO 17665 or EN 285). Its design meets drying and thermal conditioning requirements, not bioburden reduction validation protocols.
Can multiple ovens be synchronized or networked?

The Oven 125 basic dry does not support Ethernet, Wi-Fi, or RS-485 networking. Synchronization requires external PLC or SCADA integration via analog/digital I/O modules (not included).
What calibration documentation is provided?

Each unit ships with a factory calibration certificate (traceable to PTB, Germany) covering three points across the operating range (100 °C, 150 °C, 200 °C), including uncertainty budgets per ISO/IEC 17025 Annex A.
Are replacement shelves and dampers available as spare parts?

Yes—original IKA stainless steel shelves (part no. 3020000000), damper assemblies (3020000001), and door gaskets (3020000002) are stocked globally through authorized distributors.
Does the oven comply with energy efficiency regulations such as EU Ecodesign Directive 2019/2022?

Yes—the unit meets Tier 2 requirements for laboratory ovens, with standby power consumption ≤2 W and thermal insulation performance exceeding minimum U-value thresholds for Class B equipment.
