IKA Oven 125 basic dry – glass

Overview

The IKA Oven 125 basic dry – glass is a precision-engineered natural convection drying oven designed for routine laboratory thermal processing tasks including drying, sterilization, aging, and low-temperature heat treatment. Built in Staufen, Germany, it operates on the principle of gravity-driven air circulation—eliminating forced-air fans to ensure laminar, vibration-free thermal environments ideal for moisture-sensitive or particulate-prone samples. Its temperature range spans from ambient +5 °C to 250 °C, with high-stability control delivering ±0.3 K uniformity across the entire 125 L stainless steel chamber (AISI 304). The transparent double-glazed door enables real-time visual monitoring without compromising thermal integrity or operator safety—critical for time-sensitive protocols such as solvent evaporation kinetics or polymer curing validation.

Key Features

• Natural convection heating architecture ensures minimal sample disturbance and eliminates cross-contamination risks associated with fan-driven airflow
• High-efficiency thermal insulation using odorless, low-conductivity mineral wool reduces standby energy consumption to just 2 W and improves long-term operational cost efficiency
• Intuitive LED display with 0.1 K resolution and tactile membrane keypad supports precise setpoint entry, timer configuration (1–144,000 min), and real-time temperature readout
• Integrated safety features include overtemperature cut-off (independent hardware limiter), key-lock function to prevent accidental parameter changes, and IP20-rated enclosure compliant with DIN EN 60529
• USB interface enables direct connection to Windows-based PCs for time-stamped temperature logging—supporting audit-ready data capture aligned with GLP and ISO/IEC 17025 documentation requirements
• Modular interior accommodates up to six adjustable stainless steel shelves, each rated for 30 kg load capacity; optimized cavity geometry (550 × 525 × 450 mm) ensures uniform thermal distribution validated per DIN 12880

Sample Compatibility & Compliance

The Oven 125 basic dry – glass is compatible with standard laboratory glassware (e.g., Petri dishes, weighing boats, crucibles), metal trays, ceramic substrates, and polymer film carriers. Its stainless steel chamber resists corrosion from residual acids, solvents, and saline residues common in pharmaceutical stability testing or materials science workflows. The unit complies with essential European directives including EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. While not certified for Class II biological safety or explosion-proof operation, its design meets baseline requirements for ISO 14644-1 cleanroom-adjacent environments when used with appropriate procedural controls. Temperature performance validation follows DIN 12880 Part 2 methodology, supporting traceable calibration against NIST-traceable reference thermometers.

Software & Data Management

No proprietary software installation is required. The integrated USB port exports raw temperature/time logs in CSV format, enabling seamless import into Excel, MATLAB, or LIMS platforms. Timestamped records include setpoint, actual chamber temperature, elapsed time, and system status flags—fully compliant with FDA 21 CFR Part 11 requirements when paired with institutional electronic signature policies and audit trail governance. Data retention intervals are user-defined via host PC; no internal memory or cloud dependency is involved, preserving data sovereignty and simplifying IT validation.

Applications

• Moisture content determination per AOAC 950.46 and ASTM D2216 in soil, feed, and pharmaceutical excipients
• Thermal aging of polymers and composites per ISO 2578 and ASTM D3045
• Drying of filter papers and gravimetric precipitates in environmental water analysis (EPA Method 160.1)
• Pre-conditioning of test specimens prior to tensile or impact testing (ISO 291, ASTM D618)
• Low-temperature sterilization of non-critical lab tools and glassware where autoclaving is unsuitable
• Stability studies under ICH Q1A(R2) guidelines for intermediate storage conditions (e.g., 40 °C/75% RH accelerated testing support)

FAQ

Does the Oven 125 basic dry – glass support programmable ramp-soak profiles?

No—it is configured for single-setpoint operation with timer-based dwell control only. For multi-step thermal protocols, consider the IKA Oven 125 pro series with PID-based program logic.
Can the glass door be replaced with a solid stainless steel door?

No—the glass door is an integral part of the model’s structural and thermal design; retrofitting is not supported or certified by IKA.
Is the USB data logging function compatible with macOS or Linux systems?

Data export requires a Windows host running IKA’s freely available “labworldsoft” driver suite; native macOS/Linux support is not provided.
What is the recommended recalibration interval for routine GLP compliance?

Annual verification using a calibrated reference thermometer is advised; full sensor recalibration should follow ISO/IEC 17025-accredited service providers every 24 months.
Does the oven meet UL or CSA safety certification for North American laboratories?

The unit carries CE marking and complies with EN 61010-1; UL/cULus certification is available only on the IKA Oven 125 basic dry – US variant (model suffix “-US”).
