BOXUN YXQ-100G Vertical Steam Sterilizer

Overview

The BOXUN YXQ-100G Vertical Steam Sterilizer is a fully integrated, microprocessor-controlled autoclave engineered for precision sterilization and post-cycle drying of heat-stable laboratory and clinical materials. It operates on the validated principle of saturated steam under pressure—leveraging the thermodynamic properties of pressurized water vapor to achieve microbial inactivation through protein denaturation and nucleic acid disruption. Designed to meet fundamental requirements for sterility assurance in regulated environments, the YXQ-100G delivers consistent, repeatable cycles across diverse load types, including wrapped instruments, unwrapped metal tools, glassware, liquid media (with vented bottles), and porous textile loads such as gauze and surgical drapes. Its vertical orientation optimizes floor space utilization while maintaining full compliance with internationally recognized sterilization process fundamentals defined in ISO 17665-1 (Sterilization of health care products — Moist heat) and aligned with key elements of EN 285 (Large sterilizers) for cycle validation readiness.

Key Features

• Microcomputer-based intelligent control system with real-time digital display of temperature, pressure, time, and phase status
• Self-sealing silicone gasket with auto-expansion design ensures leak-tight chamber integrity during pressurization
• Interlocked handwheel door mechanism with mechanical safety lock prevents accidental opening during operation above 0.02 MPa
• Dual independent safety systems: overtemperature cutoff (activated at ≥138 °C) and overpressure relief valve (set at 0.25 MPa design limit)
• Automated cold air purge via dynamic self-venting before heating phase, ensuring uniform steam penetration
• Integrated low-water level detection with audible/visual alarm and automatic heater shutdown
• Three-stage programmable cycle logic: sterilization → exhaust → drain → drying; supports three standard operational modes (sterilize-only, sterilize+exhaust, sterilize+exhaust+drain+dry)
• Internal recirculating exhaust configuration with 3 L condensate collection bottle minimizes ambient humidity impact and improves energy efficiency
• Standard sample test port (Ø10 mm) enables integration with external temperature/pressure validation probes per IQ/OQ protocols
• Optional accessories include thermal printer (for cycle log traceability) and melt-hold function (melting range: 60–98 °C; hold range: 40–60 °C; both adjustable in 1-minute increments up to 999 minutes)

Sample Compatibility & Compliance

The YXQ-100G accommodates a broad spectrum of sterilizable items within its 100 L stainless-steel chamber (SUS304 construction throughout chamber, jacket, and baskets). Compatible loads include stainless-steel surgical instruments, borosilicate glassware (e.g., flasks, pipettes), cotton gauze packs, rubber tubing, and agar or broth media in vented containers. The unit’s chamber geometry (Ø400 mm × 850 mm) and triple-tier basket system (Ø360 mm × 240 mm × 3) support efficient load arrangement without compromising steam circulation. While not certified to FDA 510(k) or CE Class IIa medical device standards out-of-box, the sterilizer’s architecture—including documented cycle repeatability, calibrated sensor feedback loops, and audit-ready operational logs—supports user-led validation per ISO 13485 quality management systems and GLP/GMP-aligned laboratory practices. Its pressure and temperature tolerances align with minimum performance thresholds referenced in USP Sterility Assurance and ASTM E535-22 Standard Specification for Steam Sterilizers.

Software & Data Management

The embedded controller records all critical process parameters—including chamber temperature, jacket temperature, absolute pressure, elapsed time, and phase transitions—with timestamp resolution of ±1 second. Cycle data are retained onboard for ≥100 runs and can be exported via optional RS232/USB interface to external PCs for archiving. When equipped with the thermal printer option, hard-copy output includes date/time stamp, operator ID (manually entered), cycle type, setpoints, actual peak values, and pass/fail indicators based on preset deviation thresholds. All electronic records comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and support retrospective review during internal audits or regulatory inspections. Firmware supports password-protected parameter modification to prevent unauthorized changes to sterilization protocols.

Applications

This sterilizer serves core functions across academic research laboratories, hospital central sterile supply departments (CSSD), pharmaceutical QC labs, agricultural biotechnology facilities, and veterinary clinics. Typical use cases include: terminal sterilization of reusable surgical kits prior to packaging; depyrogenation of glass vials used in parenteral formulation development; preparation of microbiological growth media (e.g., nutrient agar, Sabouraud dextrose); decontamination of biohazardous waste prior to disposal; and routine sterilization of lab consumables such as Petri dishes and inoculation loops. Its robust 4.5 kW heating capacity and optimized chamber volume enable throughput scalability for medium-volume institutions requiring daily batch processing of 50–120 items per cycle.

FAQ

What is the maximum allowable working pressure and temperature?
The YXQ-100G has a maximum working pressure of 0.22 MPa and a maximum working temperature of 135 °C, with safety-rated design limits of 0.25 MPa and 138 °C.
Does the unit support validation for ISO 13485 or GMP environments?
Yes—the sterilizer’s repeatable thermal profiles, calibrated sensors, and cycle documentation capabilities provide foundational infrastructure for user-performed Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) per ISO 13485 Annex A and EU GMP Annex 15 guidelines.
Can liquid media be sterilized without boil-over?
Yes—when using vented containers and selecting appropriate slow-exhaust or gravity-displacement mode settings, the controller modulates pressure release rate to prevent violent boiling and container rupture.
Is the chamber material compatible with aggressive cleaning agents?
Yes—SUS304 stainless steel resists corrosion from common alkaline detergents, enzymatic cleaners, and diluted acidic descalers used in routine maintenance.
What electrical infrastructure is required for installation?
A dedicated 220 V ±10%, 50 Hz ±2% single-phase circuit with minimum 32 A breaker rating and proper grounding is required to accommodate peak power draw during simultaneous sterilization and drying phases.
