Chu Ding Technology LDZM-60KCS Intelligent Vertical Steam Sterilizer (60 L)

Overview

The Chu Ding Technology LDZM-60KCS Intelligent Vertical Steam Sterilizer is a Class B (EN 285-compliant) gravity-displacement and pre-vacuum capable steam sterilization system engineered for reliable, repeatable microbial inactivation in laboratory, clinical, and research environments. Operating on saturated steam under controlled pressure and temperature, the unit achieves sterility assurance levels (SAL) of 10⁻⁶ for wrapped and unwrapped instruments, culture media, glassware, and porous loads. Its vertical chamber design optimizes floor space utilization while maintaining full compliance with ISO 17665-1 (Sterilization of health care products — Moist heat) and supports validation protocols aligned with FDA 21 CFR Part 820 and EU Annex 1 requirements for sterile processing. The integrated microprocessor-based control system enables precise regulation of cycle parameters—including temperature ramp rate, dwell time, exhaust rate, and jacket preheating—ensuring consistent thermal delivery across heterogeneous load configurations.

Key Features

• Vertical stainless-steel chamber (60 L capacity) constructed from medical-grade 304 stainless steel with electropolished interior surface for corrosion resistance and ease of cleaning
• Rotary quick-opening door mechanism with dual safety interlocks: mechanical overpressure lockout and electronic lid-seal verification prior to cycle initiation
• Intelligent PID-controlled steam generation and chamber temperature regulation (50–134 °C range, ±0.5 °C accuracy at setpoint)
• Programmable cycle timer (0–99 hours) with memory for up to 12 user-defined sterilization profiles
• Digital LCD display with Chinese-language interface showing real-time status: phase (heat-up, sterilize, exhaust, dry), temperature, pressure, elapsed time, and error codes
• Internal exhaust system eliminates external steam venting during cooldown, reducing ambient humidity and improving lab safety
• Automatic water-level monitoring with audible/visual alarm and power cutoff if low-water condition is detected
• Built-in acoustic end-of-cycle alert followed by automatic power-down; optional RS232 or USB interface for external printer integration
• Factory-configurable drying phase (optional accessory) supporting post-sterilization moisture removal for wrapped instrument packs and textiles

Sample Compatibility & Compliance

The LDZM-60KCS accommodates a broad spectrum of sterilizable materials including but not limited to: stainless-steel surgical instruments, borosilicate glassware, rubber tubing, textile wraps, agar and broth media in sealed containers, and non-porous polymer components. It meets the functional requirements of EN 13060 (Small steam sterilizers) for Type B cycles and supports both gravity displacement (for solid, non-porous items) and pre-vacuum-assisted air removal (for porous and hollow loads). All electrical components conform to IEC 61010-1 safety standards. The sterilizer’s documentation package includes IQ/OQ templates compatible with GLP and GMP audit trails, and its control firmware supports audit-log generation (time-stamped event records) required under FDA 21 CFR Part 11 when paired with compliant data management software.

Software & Data Management

While the base unit operates via embedded firmware without cloud connectivity, its control architecture supports traceable data capture through optional serial output (RS232) or USB host mode. When connected to a validated PC-based logging application, users can export cycle reports—including start/end timestamps, peak temperature, minimum/maximum pressure, and fault logs—for inclusion in quality records. Firmware versioning, parameter lockout settings (admin vs. operator access levels), and password-protected profile editing ensure procedural integrity. Cycle validation files (e.g., thermocouple mapping reports, Bowie-Dick test logs) may be archived externally per ISO 13485 clause 7.5.10.

Applications

This sterilizer serves core functions across academic research laboratories (microbiology, cell culture, molecular biology), hospital central sterile supply departments (CSSD), pharmaceutical QC labs, food safety testing facilities, and veterinary diagnostic centers. Typical use cases include: sterilization of Petri dishes and pipette tips prior to aseptic technique; decontamination of biohazardous waste before disposal; preparation of autoclavable media formulations; reprocessing of reusable surgical kits; and validation of sterilization process parameters during equipment qualification (IQ/OQ/PQ). Its 60 L chamber volume balances throughput efficiency with benchtop footprint constraints common in mid-sized labs.

FAQ

What sterilization standards does the LDZM-60KCS comply with?
It conforms to EN 13060 (Type B small steam sterilizers), ISO 17665-1 (moist heat sterilization), and incorporates design elements aligned with ISO 11140 (chemical indicators) and ISO 11737-1 (microbiological methods for sterilization validation).
Can this unit perform vacuum-assisted cycles?
Yes—the LDZM-60KCS includes a built-in vacuum pump option enabling pre- and post-sterilization vacuum phases, essential for effective air removal from lumened devices and porous loads.
Is third-party validation support available?
Chu Ding Technology provides IQ/OQ protocol templates and factory calibration certificates; final PQ must be conducted on-site by qualified personnel using calibrated thermocouples and biological indicators (e.g., Geobacillus stearothermophilus spore strips).
Does the unit require a dedicated steam generator?
No—it features an integrated electric heating element and water reservoir; connection to municipal steam lines is not supported or recommended.
What maintenance intervals are recommended?
Daily: chamber wipe-down and gasket inspection; weekly: drain valve flush and door seal lubrication; annually: pressure transducer recalibration and safety valve certification by an accredited service provider.
