Overview
The IRM G75 Vertical High-Pressure Steam Sterilizer is an engineered solution for reliable, repeatable, and fully traceable terminal sterilization of heat-stable laboratory materials—including culture media, glassware, surgical instruments, and biohazardous waste. Operating on the validated principle of saturated steam under pressure, the G75 achieves microbiological lethality through precise control of temperature (up to 141 °C) and corresponding absolute pressure (0.3 MPa), ensuring compliance with internationally recognized sterilization kinetics defined in ISO 17665-1 and EN 285. Unlike conventional autoclaves, the G75 integrates zero-steam-emission technology—condensing all process vapor internally via a built-in cooled water reservoir—eliminating ambient humidity rise, reducing HVAC load, and maintaining cleanroom-compatible environmental conditions. Its vertical configuration optimizes footprint efficiency while accommodating standard 75 L chamber volume for high-throughput workflows in academic labs, QC facilities, and small-scale bioproduction environments.
Key Features
- Integrated iSmart dual-controller architecture: PID-based thermal regulation combined with PLC-driven logic sequencing ensures ±0.3 °C temperature stability and <±5 kPa pressure repeatability across cycles.
- iSpeed rapid-cooling system reduces post-cycle dwell time to approximately 6 minutes before safe lid access—enhancing throughput without compromising sterility assurance.
- Dual-layer dry-run protection: Real-time ultrasonic water-level sensing at startup plus redundant thermal cutoffs prevent heater activation below minimum fill level.
- Full mechanical and electronic door interlock: Lid position is continuously monitored; sterilization cycle initiates only when full sealing torque is confirmed and maintained throughout operation.
- Three programmable exhaust strategies—full, pulsed, or non-exhaust—allow tailored pressure decay profiles for liquid, solid, or porous load types per ISO 11140-5 recommendations.
- 7-inch capacitive touchscreen interface with intuitive icon-driven navigation, multilingual support (English, Spanish, German, French), and user-accessible calibration logs.
- Comprehensive self-diagnostic suite: Monitors SSR output integrity, CPU health, sensor continuity, valve actuation timing, and circuit-level anomalies—each logged with timestamp and error code.
Sample Compatibility & Compliance
The G75 accommodates standard stainless-steel baskets (Ø370 mm × 220 mm height, 5×5 mesh), compatible with Petri dishes, Erlenmeyer flasks, pipette tips, forceps, and wrapped instrument packs. Chamber geometry supports uniform steam penetration verified by thermocouple mapping per ANSI/AAMI ST79 Annex B. The system meets essential requirements of GB 8599–2008 (Chinese national standard for sterilizers), aligns with key clauses of ISO 13485:2016 for medical device manufacturing environments, and provides audit-ready documentation trails suitable for GLP and GMP-aligned laboratories. Optional accessories—including calibrated PT100 sample temperature probes, pressure transducers, and FDA 21 CFR Part 11-compliant data loggers—enable full validation support for IQ/OQ/PQ protocols.
Software & Data Management
The embedded iSmart OS stores ≥10,000 complete cycle records locally—including start/stop timestamps, setpoints, actual temperature/pressure curves, exhaust mode selection, and diagnostic flags. USB export enables CSV-formatted data transfer for external analysis in MATLAB, JMP, or LIMS platforms. Optional Ethernet/WiFi modules support remote monitoring via browser-based dashboards with role-based user permissions. All critical parameters are digitally signed at cycle completion to prevent post-hoc tampering—meeting ALCOA+ data integrity principles required under regulatory inspections.
Applications
- Autoclaving of nutrient agar, tryptic soy broth, and other heat-stable liquid media in research and clinical microbiology labs.
- Sterilization of reusable glassware, stainless-steel tools, and textile wraps in hospital central sterile supply departments (CSSD).
- Decontamination of Category B biological waste prior to disposal per WHO and CDC biosafety guidelines.
- Pre-sterilization conditioning of bioreactor components and filtration housings in pilot-scale upstream processing.
- Thermal validation studies requiring reproducible exposure at 121 °C (15 min), 134 °C (3 min), or extended hold at 141 °C for spore challenge testing.
FAQ
Does the G75 require external steam supply?
No—the G75 generates saturated steam internally via electric heating elements and distilled/deionized water; no external boiler or steam line is needed.
Can the system be validated for pharmaceutical use?
Yes—when equipped with Class A PT100 probe ports, integrated pressure transducers, and 21 CFR Part 11-compliant data logging, it supports full GMP validation per EU Annex 1 and USP <1229>.
What maintenance intervals are recommended?
Weekly chamber seal inspection, monthly drain filter cleaning, and annual verification of safety valves and temperature sensors per manufacturer’s service manual.
Is the zero-steam-emission design certified?
Yes—the internal condensation system complies with ISO 15883-1 Annex C for vapor containment and has been independently verified for <0.1 g/m³ ambient humidity increase during operation.
How is firmware updated?
Firmware updates are delivered via encrypted USB stick with digital signature verification; version history and update logs are retained in the system audit trail.
