Overview
The YX600W Horizontal Steam Sterilizer is a CE-compliant, microprocessor-controlled autoclave engineered for reliable, repeatable sterilization of heat- and moisture-stable laboratory, clinical, and pharmaceutical materials. It operates on the principle of saturated steam under pressure—leveraging the well-established thermodynamic relationship between steam temperature, absolute pressure, and microbial lethality—to achieve sterility assurance levels (SAL) of ≤10⁻⁶ in accordance with ISO 17665-1 and EN 285 standards. Designed for continuous operation in high-throughput environments, the unit integrates dual-sensor monitoring (chamber and water reservoir), real-time PID temperature regulation, and fail-safe mechanical interlocks to ensure process integrity across all operational phases: conditioning, exposure, and drying.
Key Features
- Stainless steel 304 chamber and jacket construction for corrosion resistance and long-term structural integrity under repeated thermal cycling
- Full-cycle microcomputer control with LED digital display showing setpoint and real-time chamber temperature, elapsed time, and pressure values
- Dual independent pressure and temperature monitoring: separate sensors for steam generator water tank and sterilization chamber, enabling precise thermal validation and fault isolation
- Interlocked door mechanism: steam injection is physically inhibited until the door is fully sealed and mechanically locked; pressure-based safety lock prevents door rotation when chamber pressure exceeds 10 kPa
- PID temperature control algorithm with auto-tuning capability—adjusts heating parameters dynamically to suppress overshoot and maintain ±0.5 °C thermal stability during dwell phase
- Overtemperature protection: automatic heater cutoff if chamber temperature exceeds setpoint by >2 °C, followed by audible/visual alarm activation
- Intelligent water management system: detects low water level in reservoir, suspends heating, initiates automatic refill, and resumes sterilization only after minimum water level is restored
- Self-expanding silicone rubber gasket ensuring uniform radial sealing force and service life exceeding 5,000 cycles under normal operating conditions
- Programmable post-sterilization exhaust modes—including slow vent, fast vent, and vacuum-assisted drying—for optimized handling of liquids, wrapped instruments, porous loads, and moisture-sensitive items
- Integrated drying function enabled during water tank standby mode, supporting residual moisture removal without requiring secondary equipment
Sample Compatibility & Compliance
The YX600W accommodates standard stainless steel instrument trays, glassware, textile packs, autoclavable plastic containers (e.g., polypropylene, polycarbonate), and liquid media bottles up to 2 L volume. Its 300 L cylindrical chamber (Ø400 mm × 600 mm) supports full-load sterilization per cycle while maintaining uniform steam penetration via bottom-inlet steam distribution. The system complies with ISO 13485:2016 (medical device quality management), meets essential requirements of the EU Medical Device Regulation (MDR 2017/745) Annex I for Class IIa devices, and supports validation protocols aligned with ISO 17665-2 (process development) and EN 554 (sterilization process requirements). All safety-critical components—including pressure relief valve (ASME BPVC Section VIII compliant), overpressure cut-off switch, and door locking assembly—are certified to PED 2014/68/EU.
Software & Data Management
While the YX600W operates via embedded firmware without external PC connectivity, its controller logs critical process parameters—including start time, set temperature, actual chamber temperature profile, pressure trace, dwell duration, and alarm events—into non-volatile memory with timestamping. Data export is supported via optional RS-232 or USB interface (hardware module sold separately), enabling integration into laboratory information management systems (LIMS) or electronic batch records. Audit trail functionality satisfies basic GLP/GMP documentation needs, including user ID tagging for cycle initiation and parameter modification. For regulated environments, optional validation packages include IQ/OQ documentation templates compliant with FDA 21 CFR Part 11 (when paired with validated data acquisition software).
Applications
This sterilizer serves core functions across academic research laboratories, hospital central sterile supply departments (CSSD), contract manufacturing organizations (CMOs), and biotech pilot facilities. Typical use cases include: terminal sterilization of surgical instruments and implant packaging; depyrogenation of glass vials and stoppers; preparation of microbiological growth media; decontamination of biohazardous waste prior to disposal; and routine sterilization of reusable labware such as pipette tips, Petri dishes, and centrifuge tubes. Its programmable exhaust sequencing makes it suitable for both solid-load sterilization (e.g., linen packs) and liquid-phase processes (e.g., agar media), minimizing boil-over risk through controlled depressurization.
FAQ
What is the maximum allowable working pressure of the YX600W chamber?
The rated maximum gauge pressure is 150 kPa (1.5 bar), corresponding to a saturated steam temperature of 121.3 °C at sea level.
Does the unit support validation with temperature mapping probes?
Yes—the chamber features three standardized 3 mm diameter probe ports (top, middle, and bottom) conforming to ISO 17665-2 Annex B for thermocouple insertion during qualification studies.
Is the YX600W suitable for sterilizing liquids in sealed containers?
It supports liquid sterilization using slow-exhaust mode to prevent container rupture; however, sealed ampoules or fully capped bottles require specialized vacuum-assisted cycles not natively available—consult technical documentation for load-specific configuration guidance.
What maintenance intervals are recommended for routine operation?
Daily: visual inspection of door seal, drain filter cleaning, and water level verification. Quarterly: calibration check of pressure transducer and temperature sensor against NIST-traceable references. Annually: full safety valve certification and gasket integrity assessment per EN 285 Clause 9.3.
Can the sterilizer be integrated into a building’s central steam supply?
No—it is self-contained with an integrated electrically heated water reservoir and does not accept external steam input; external steam compatibility requires retrofitting with a dedicated steam inlet manifold and pressure-reducing station (not supplied).
