BOXUN YXQ-30SII Vertical Steam Sterilizer

Overview

The BOXUN YXQ-30SII Vertical Steam Sterilizer is a fully self-contained, microprocessor-controlled autoclave engineered for reliable saturated steam sterilization in laboratory, clinical, and research environments. It operates on the fundamental principle of moist heat sterilization—utilizing pressurized saturated steam at elevated temperatures to achieve microbial inactivation through protein denaturation and nucleic acid disruption. Designed to meet internationally recognized sterilization process requirements—including those aligned with ISO 17665-1 (Sterilization of health care products — Moist heat — Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices)—the YXQ-30SII delivers consistent, traceable, and repeatable cycles across diverse load types. Its vertical orientation optimizes floor space usage without compromising chamber volume or thermal uniformity, making it particularly suitable for institutions requiring compact yet high-capacity sterilization capability.

Key Features

• Patented handwheel-type quick-opening safety interlock system ensures mechanical and electronic dual verification before door release—preventing accidental opening under pressure.
• SUS304 stainless steel construction throughout critical components (chamber, door, basket, and outer shell) provides long-term resistance to corrosion from repeated exposure to steam, condensate, and cleaning agents.
• Intelligent microcomputer control system with real-time digital display of temperature, pressure, and remaining time; supports programmable cycle selection for liquid, solid, and wrapped instrument modes.
• Automatic cold air purge function initiates prior to sterilization phase to ensure complete air removal—critical for achieving uniform steam penetration and eliminating cold spots.
• Integrated safety protections include low-water level alarm, dry-run prevention, overtemperature cutoff (138 °C design limit), overpressure relief valve (set at 0.25 MPa), and automatic pressure release upon cycle completion.
• Acoustic end-of-cycle alert and optional RS232 interface support integration into lab-wide equipment monitoring systems; standard sample test port enables thermocouple validation during qualification studies.

Sample Compatibility & Compliance

The YXQ-30SII accommodates a broad spectrum of sterilizable materials, including surgical instruments, glassware, textile dressings, rubber tubing, culture media (in sealed containers), and polymer-based labware compatible with moist heat. Load configuration adheres to ISO 11140-1 guidelines for packaging integrity and steam permeability. While not certified for terminal sterilization of implantables per ISO 11135, the unit satisfies essential performance criteria for non-critical and semi-critical item reprocessing as defined in AAMI ST79:2023. Its operational parameters align with national standards GB 8599–2008 (China) and support GLP-compliant documentation when paired with external data loggers or optional thermal printer accessories.

Software & Data Management

The embedded controller records cycle parameters—including start time, target temperature/pressure, hold duration, and final exhaust status—in non-volatile memory for up to 99 completed runs. Cycle logs are retrievable via front-panel navigation and support manual audit trail review. For enhanced data integrity, optional thermal printers (sold separately) provide hard-copy output compliant with basic ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate). Though the base unit does not natively support FDA 21 CFR Part 11 electronic signature functionality, its deterministic cycle execution and hardware-enforced safety interlocks facilitate validation under GMP and ISO 13485 quality management systems.

Applications

This sterilizer serves core functions across academic laboratories, hospital central sterile supply departments (CSSD), pharmaceutical QC labs, veterinary clinics, and agricultural research facilities. Typical use cases include: depyrogenation of glass vials prior to aseptic filling; sterilization of agar plates and broth media for microbiological assays; decontamination of reusable PPE and surgical kits; validation of autoclave performance using biological indicators (e.g., Bacillus stearothermophilus spore strips); and routine processing of animal husbandry tools in biosafety Level 2 (BSL-2) containment settings. Its 30 L chamber supports mixed loads up to 20 kg (including packaging weight), enabling efficient batch throughput without compromising thermal homogeneity.

FAQ

What is the maximum allowable load weight for the YXQ-30SII chamber?
The recommended maximum load mass is 20 kg, inclusive of container weight and moisture content—exceeding this may impair steam circulation and compromise sterilization efficacy.
Does the unit comply with international sterilization validation standards?
Yes—the YXQ-30SII meets thermal performance benchmarks outlined in ISO 17665-1 for routine sterilization cycles; full validation (IQ/OQ/PQ) requires user-conducted thermocouple mapping and biological indicator testing.
Can the sterilizer be used for liquid media sterilization?
Yes, it includes a dedicated “Liquid” cycle mode with controlled cooling and pressure release to prevent boil-over; users must ensure containers are vented or loosely capped.
Is third-party calibration and certification available?
BOXUN-certified service engineers provide on-site calibration of temperature and pressure sensors, along with IQ/OQ documentation packages traceable to NIST standards.
What maintenance intervals are recommended?
Daily: chamber inspection, gasket cleaning, and water level check. Quarterly: safety valve functional test and door seal integrity verification. Annually: full sensor recalibration and control system firmware update.
