Overview
The Shanghai Yilong LDZX-50KBS is a vertical, full stainless steel autoclave engineered for reliable, repeatable steam sterilization under saturated steam pressure conditions. It operates on the fundamental principle of moist heat sterilization—utilizing pressurized saturated steam at elevated temperatures (typically 121 °C at 103 kPa or 134 °C at 206 kPa) to achieve microbial inactivation through protein denaturation and nucleic acid disruption. Designed to meet national medical-grade sterilization standards equivalent to GB 8599–2008 and aligned with ISO 17665-1:2012 requirements for sterilization by moist heat, the LDZX-50KBS serves as a core sterilization platform in regulated laboratory environments where consistent bioburden reduction is mandatory.
Key Features
- Full 304 stainless steel construction—including chamber, door, jacket, and internal components—for exceptional corrosion resistance, long-term structural integrity, and compliance with cleanroom-compatible surface finish requirements.
- Vertical orientation with front-loading design optimizes floor space utilization in compact laboratories while enabling ergonomic loading/unloading of standard sterilization trays, instrument baskets, and media bottles.
- Microprocessor-controlled PID temperature and pressure regulation ensures precise setpoint maintenance, minimal overshoot, and automatic cycle termination upon completion.
- Integrated safety mechanisms include overtemperature/overpressure cutoffs, door interlock system preventing opening during pressurized operation, steam trap with automatic condensate discharge, and dual-pressure gauge (analog + digital) for real-time monitoring.
- Programmable sterilization cycles support gravity displacement and pre-vacuum modes (where applicable), accommodating variable load types including wrapped instruments, porous materials, liquids, and heat-labile solutions via slow-cool and liquid-specific ramp profiles.
Sample Compatibility & Compliance
The LDZX-50KBS accommodates a broad range of sterilizable items: surgical instruments, cotton gauze and linen packs, glassware (e.g., flasks, pipettes), stainless steel containers, nutrient agar and broth media, pharmaceutical aqueous solutions, and polymer-based labware rated for autoclaving (e.g., polypropylene centrifuge tubes). All sterilization cycles are validated per ISO 11134 and ISO 11140-1 for biological indicator response, supporting routine verification using Bacillus stearothermophilus spore strips or self-contained indicators. The unit conforms to GB/T 30690–2014 (Sterilization Equipment for Laboratory Use) and supports documentation traceability required under GLP and GMP frameworks, including manual logbook entries and optional external data logging interfaces.
Software & Data Management
While the LDZX-50KBS features an embedded microcontroller without built-in PC connectivity, it provides comprehensive local cycle documentation via LED display showing real-time temperature, pressure, elapsed time, and phase status (heat-up, sterilize, exhaust, dry). Optional RS-232 or USB data export modules enable integration with laboratory information management systems (LIMS) for audit-ready record retention. Cycle parameters—including set temperature, hold time, and pressure profile—are user-configurable and retained in non-volatile memory. For regulated environments, users may implement supplementary electronic records compliant with FDA 21 CFR Part 11 via third-party validation packages that include electronic signatures, audit trails, and user access controls.
Applications
This autoclave is routinely deployed across academic research laboratories, hospital central sterile supply departments (CSSD), pharmaceutical QC labs, food safety testing facilities, and biotechnology R&D centers. Typical use cases include sterilization of microbiological culture media prior to inoculation; decontamination of reusable surgical tools and dental handpieces; preparation of sterile saline and buffer solutions; validation of sterilization protocols for Class B loads per EN 13060; and routine processing of biohazardous waste in BSL-2 settings. Its robust thermal uniformity and reproducible lethality (F0 ≥ 12 min for standard 121 °C/15 min cycles) make it suitable for both routine and validation-grade operations.
FAQ
What is the chamber volume of the LDZX-50KBS?
The nominal chamber capacity is 50 liters, optimized for standard sterilization trays measuring up to 320 × 280 × 120 mm.
Does the unit support vacuum-assisted air removal?
The base LDZX-50KBS model utilizes gravity displacement; optional vacuum pump integration is available for enhanced air removal in porous or multi-layered loads.
Is third-party IQ/OQ/PQ validation support provided?
Yes—Shanghai Yilong supplies protocol templates and factory test reports; certified validation engineers can perform on-site qualification per ISO 13485 and Annex 1 requirements.
Can liquid media be sterilized without boil-over?
Yes—the programmable slow-cool and liquid cycle modes regulate exhaust rate and pressure decay to prevent container rupture and medium evaporation.
What maintenance intervals are recommended?
Daily: Chamber inspection and gasket cleaning. Weekly: Drain valve function check and water level sensor verification. Annually: Pressure transducer calibration and safety valve certification by accredited metrology service.
