IRM A100 Vertical High-Pressure Steam Sterilizer

Overview

The IRM A100 Vertical High-Pressure Steam Sterilizer is an engineered solution for reliable, repeatable, and compliant terminal sterilization of heat-stable laboratory materials—including culture media, glassware, surgical instruments, and biohazardous waste. It operates on the fundamental principle of saturated steam under elevated pressure to achieve microbial inactivation through protein denaturation and nucleic acid disruption. At 0.3 MPa (≈3 bar gauge), the chamber achieves a maximum operating temperature of 141 °C—exceeding the standard 121 °C/15 psi benchmark required by ISO 17665-1 and EN 285 for porous load sterilization validation. Its 100 L cylindrical chamber (Ø400 × 778 mm) supports high-throughput processing while maintaining uniform thermal distribution, validated per ANSI/AAMI ST79:2017 Annex E for temperature mapping and load penetration.

Key Features

• Robust dual-safety architecture: integrated active safeguards (real-time pressure/temperature monitoring, SSR-controlled heating, door interlock verification) and passive protections (mechanical safety valve, independent overpressure cutoff, dry-run prevention, dual overtemperature sensors).
• iSpeed rapid-cooling system enables safe lid opening in approximately 6 minutes post-cycle—reducing turnaround time by up to 40% compared to conventional gravity-displacement units, as verified under routine operational qualification (OQ) protocols.
• 7-inch full-color TFT touchscreen with intuitive iSmart interface supports multi-language operation (English, Spanish, French, German), programmable user profiles, and context-sensitive help prompts—designed for compliance with human factors engineering guidelines per IEC 62366-1.
• Eight preconfigured sterilization modes: Media Sterilization, Instrument Sterilization, Solid Load, Liquid Load, Waste Decontamination, Sterilize-Hold, Dissolution-Hold, and Vessel Preheat—each with adjustable time/temperature parameters across 0–999 h 59 min ranges.
• Three programmable exhaust strategies—full exhaust, pulsed vacuum-assisted exhaust, and no-exhaust hold—allow precise control over cooling rate and moisture retention, critical for liquid media stability and glassware drying efficiency.
• Upward-swinging lid with infinitely adjustable positioning and mechanical gas spring assist ensures ergonomic sample loading/unloading and eliminates traditional hinge fatigue or lid-drop hazards.
• SUS304 stainless steel chamber and titanium alloy heating elements ensure long-term corrosion resistance and thermal stability under repeated autoclave cycles.

Sample Compatibility & Compliance

The A100 accommodates a broad range of load types: wrapped or unwrapped instruments, Petri dishes, flasks, pipette tips, agar plates, and regulated biohazardous waste bags. Its chamber geometry and steam distribution design support validation for mixed-load configurations per ISO 11140-1 and USP . The unit meets essential electrical safety requirements per IEC 61010-1 and carries CE marking for conformity with the EU Medical Device Regulation (MDR) Annex I essential requirements for Class IIa sterilizers. Optional data logging (via RS485 or USB) supports 21 CFR Part 11-compliant audit trails when paired with validated third-party software—enabling traceability for GLP, GMP, and ISO/IEC 17025-accredited laboratories.

Software & Data Management

The embedded iSmart controller logs all critical process parameters—including chamber temperature, jacket pressure, elapsed time, and door status—with timestamped records stored internally (≥10,000 cycles). Optional printer or thermal recorder modules generate hard-copy cycle reports meeting FDA and EU Annex 11 documentation standards. All programs support password-protected access levels (operator, technician, administrator), electronic signature capability, and automatic backup to external USB drives. Firmware updates are performed via secure authenticated protocols, preserving configuration integrity during version upgrades.

Applications

• Routine sterilization of microbiological growth media (e.g., LB, TSA, Sabouraud Dextrose Agar) without caramelization or pH shift.
• Terminal decontamination of sharps, forceps, scalpels, and reusable labware in academic, clinical, and pharmaceutical QC labs.
• Pre-sterilization conditioning of bioreactor vessels and fermentation tanks per cGMP Annex A guidelines.
• Regulatory-compliant inactivation of Category B biological waste prior to disposal, satisfying WHO BSL-2 and CDC/NIH biosafety recommendations.
• Temperature-controlled dissolution and holding of thermolabile reagents where precise thermal ramping and dwell control are required.

FAQ

What is the maximum validated sterilization temperature and corresponding pressure?
The A100 achieves a maximum sterilization temperature of 141 °C at 0.3 MPa (gauge), exceeding the minimum requirements for extended-cycle sterilization per ISO 17665-1 Annex C.

Does the unit support automated validation protocol execution?
Yes—when equipped with optional temperature and pressure transducers, the A100 can execute IQ/OQ/PQ sequence scripts with real-time deviation alerts and auto-generated validation reports.

Is the chamber volume calibrated and traceable to national standards?
Chamber volume is determined geometrically per ASTM E2500-13 and verified during factory acceptance testing using NIST-traceable dimensional metrology tools.

Can the sterilizer be integrated into a central lab management system?
Via Modbus RTU or Ethernet/IP protocols (optional communication module), the A100 supports bidirectional integration with LIMS and MES platforms for centralized cycle monitoring and alarm forwarding.

What maintenance intervals are recommended for regulatory compliance?
Daily checks (seal integrity, water level, drain function), weekly chamber inspection, and annual calibration of temperature/pressure sensors per ISO/IEC 17025-accredited service providers are advised.
