Overview

The Jihepu YX-18HDD Stainless Steel Portable Steam Autoclave is a gravity-displacement, saturated-steam sterilization system engineered for reliable, repeatable microbial inactivation in resource-constrained or mobile laboratory environments. It operates on the fundamental principle of moist heat sterilization—utilizing pressurized saturated steam to achieve thermal lethality against bacteria, spores, viruses, and fungi. At 126 °C and 0.14–0.16 MPa, the unit delivers a minimum F₀ value sufficient for sterilizing wrapped instruments, culture media, saline solutions, gauze, glassware, and other heat-stable lab materials in accordance with ISO 17665-1:2019 and EN 285:2015 standards for steam sterilization processes. Its compact footprint and self-contained design make it suitable for decentralized settings—including rural clinics, field research stations, teaching laboratories, and small-scale bioprocessing units—where fixed central sterilization infrastructure is unavailable or impractical.

Key Features

• Full stainless steel construction (AISI 304 grade) ensures long-term corrosion resistance to repeated exposure to condensate, saline solutions, and alkaline cleaning agents—critical for compliance with GLP maintenance protocols.
• Integrated dual-safety system: mechanical pressure relief valve (set point: 0.165 MPa) and independent low-water-level cutoff with thermal cutoff and audible alarm prevent dry-heating and chamber deformation.
• Precision analog pressure/temperature gauge with dual-scale calibration (MPa and °C) enables real-time verification of process parameters without external instrumentation.
• Immersion-type heating element with PID-regulated power delivery ensures stable temperature ramping and minimal overshoot during cycle initiation.
• User-configurable time-temperature profiles: adjustable sterilization duration (0–99 min) and setpoint temperature (105–126 °C) support validation of diverse load types—from liquid media (requiring slow exhaust) to porous loads (requiring fast exhaust).
• Gravity displacement chamber design eliminates need for vacuum pumps or complex air removal cycles—reducing maintenance complexity and energy consumption.

Sample Compatibility & Compliance

The YX-18HDD accommodates standard sterilization loads including wrapped surgical instruments, cotton gauze packs, Petri dishes, Erlenmeyer flasks (up to 500 mL), and pre-filled media bottles. Load configuration must comply with ISO 11140-1:2014 guidelines for steam penetration: items must be arranged to allow unobstructed steam flow and condensate drainage. The unit meets essential safety requirements under IEC 61010-1:2010 for laboratory electrical equipment and incorporates design elements aligned with FDA 21 CFR Part 820 (QSR) for medical device manufacturing environments. While not certified for Class B vacuum-assisted cycles per EN 13060, its gravity-displacement performance is validated for Class N applications as defined in EN 13060:2014+A2:2021.

Software & Data Management

This model operates via electromechanical controls without embedded digital firmware or data logging capability. All operational parameters—including set temperature, elapsed time, and pressure—are monitored visually via analog gauges and manually recorded for batch traceability. For regulated environments requiring audit trails, users may integrate external calibrated thermocouple loggers (e.g., compliant with ASTM E2850–22) into the chamber during qualification studies. Documentation templates for IQ/OQ/PQ execution—including temperature mapping protocols and biological indicator challenge testing (using Geobacillus stearothermophilus spores) —are provided in the English-language user manual to support GMP/GLP-compliant implementation.

Applications

• Routine sterilization of reusable stainless-steel tools and glassware in academic teaching labs and veterinary clinics.
• Preparation of microbiological growth media and buffer solutions in field-based molecular biology workflows.
• Decontamination of biohazardous waste in biosafety level 1 (BSL-1) containment areas prior to disposal.
• On-site sterilization of dental handpieces and orthodontic instruments in mobile health units.
• Production of potable water in remote industrial sites via extended boiling cycles at elevated pressure (validated per WHO Guidelines for Drinking-water Quality, 4th ed.).

FAQ

What is the maximum recommended load weight for consistent sterilization efficacy?

For optimal steam penetration and thermal uniformity, total load mass should not exceed 8 kg when fully saturated. Overloading reduces chamber air removal efficiency and increases cycle variability.

Can this autoclave be used for sterilizing liquids in sealed containers?

Yes—provided containers are vented or fitted with sterile filters, and sterilization cycles include a slow exhaust phase to prevent boil-over. Liquid loads require extended hold times (≥20 min at 121 °C or ≥15 min at 126 °C) per ISO 17665-1 Annex C.

Is third-party validation support available?

Jihepu provides technical documentation packages—including dimensional drawings, material certifications (EN 10088-1), and electrical schematics—for integration into site-specific validation protocols conducted by qualified QA personnel or external auditors.

How often should the safety valve be functionally tested?

Per EN 285:2015 Clause 7.3.2, the mechanical pressure relief valve must undergo manual lift testing before each daily operation and full recalibration annually by an accredited metrology service.

Does the unit comply with electromagnetic compatibility (EMC) directives for export?

The YX-18HDD meets IEC 61326-1:2012 Class B emission limits for laboratory equipment. CE marking is not applied; users must verify regional conformity (e.g., UKCA, KC, or NRCan) through local authorized representatives prior to import.
