Overview
The IRM IFE115 Precision Incubator is an engineered-for-reliability benchtop incubation system designed for demanding life science applications requiring high thermal stability and reproducible environmental control. Unlike general-purpose incubators, the IFE115 employs a forced-air convection architecture with adjustable fan speed, enabling precise temperature regulation across its full operating range—from ambient +5°C up to 220°C—making it suitable not only for microbial or cell culture but also for accelerated stability testing, enzyme inactivation studies, and materials aging protocols. Its core control system utilizes a dual-PID algorithm architecture, supporting independent tuning for low-, mid-, and high-temperature zones, with auto-tuning capability to optimize response dynamics under varying load conditions. Temperature resolution is 0.1°C, and the system achieves ≤±0.2°C temperature fluctuation (measured over 24 h at setpoint), with uniformity validated per ISO 15265:2021 Annex B methodology at key reference points (center, corners, top/mid/bottom). The chamber is constructed from electropolished stainless steel (interior) and cold-rolled steel with epoxy-powder coating (exterior), ensuring corrosion resistance and long-term dimensional stability.
Key Features
- Forced-air convection with continuously adjustable fan speed for optimized heat distribution and reduced thermal stratification
- Dual- or triple-zone PID temperature control with auto-tuning function and manual parameter override
- Temperature correction offset function (±9.9°C range) for calibration traceability against NIST-traceable reference thermometers
- Comprehensive safety architecture: independent mechanical over-temperature protector (cut-off at 230°C), integrated electronic over-temperature alarm, residual-current circuit breaker (30 mA sensitivity), and door-interlock switch that deactivates heating upon opening
- Real-time operational logging: run time, elapsed time, segment progress, cycle count, and fan speed—all simultaneously displayed on the 4.3-inch LCD interface
- Programmable operation modes: constant setpoint, timed run, delayed start (up to 9999 h), and multi-segment ramp-soak profiles (up to 50 segments, 99 cycles)
- Power-loss recovery with memory retention: resumes prior program state—including active segment and remaining time—after grid interruption
Sample Compatibility & Compliance
The IFE115 accommodates standard laboratory vessels including Petri dishes, flasks (up to 2 L), multi-well plates, and glassware up to 300 mm in height. Internal dimensions (500 × 450 × 510 mm W×D×H) support up to six 470 × 420 mm stainless steel shelves (standard: two; fully equipped: six), each rated for 30 kg static load. All internal surfaces are seamless and crevice-free to facilitate cleaning and minimize contamination risk. While humidity control is not integrated, the unit complies with IEC 61010-1:2010 for electrical safety and meets EMC requirements per IEC 61326-1:2021 Class B. It supports GLP/GMP-aligned workflows through optional data integrity add-ons (e.g., external temperature recorder with 21 CFR Part 11–compliant audit trail).
Software & Data Management
The embedded controller provides native USB port connectivity for U-disk-based data export: temperature logs (CSV format), real-time curve snapshots, and event timestamps (door open/close, over-temp alarm, power loss). No proprietary software is required—exported files are compatible with Excel, MATLAB, and LIMS platforms. Optional accessories include a standalone temperature recorder (model TR-16) offering continuous 16-channel monitoring with password-protected configuration and encrypted SD-card storage. For integration into centralized lab networks, RS-485 Modbus RTU protocol support enables bidirectional communication with building management systems or SCADA platforms.
Applications
- Bacterial and fungal cultivation under elevated temperature conditions (e.g., thermophile screening at 60–80°C)
- Protein denaturation kinetics and thermal stability assays (e.g., DSC pre-screening support)
- Accelerated shelf-life testing of pharmaceutical excipients and medical device packaging materials
- Controlled drying of moisture-sensitive reagents and lyophilized intermediates
- Pre-heating and conditioning of test samples prior to mechanical or rheological analysis
- Environmental stress testing of electronic components per JEDEC JESD22-A108F guidelines
FAQ
Does the IFE115 support humidity control?
No—this model is a dry-heat precision incubator. Humidity control is not available as a factory option or field retrofit.
Can the unit be validated for GxP environments?
Yes—when paired with an external 21 CFR Part 11–compliant temperature recorder and IQ/OQ documentation package (available upon request), the system meets baseline qualification requirements for non-sterile stability chambers.
What is the maximum shelf loading capacity?
Each shelf supports up to 30 kg; total chamber load must not exceed 60 kg to maintain specified uniformity and airflow dynamics.
Is the internal chamber volume verified per ISO 15265?
Yes—the stated 115 L net volume is measured per ISO 15265:2021 Section 6.2 using calibrated volumetric displacement methods.
Can I upgrade from LCD to touch interface post-purchase?
No—the IFE and IFEP series use distinct controller hardware platforms; interface upgrades require full control module replacement and are not cost-effective.
