Lingda LDZH-150KBS & LDZX-100KBS Vertical Steam Sterilizers (Class B / N-Type, Full Stainless Steel, Manual-Lever Quick-Opening)

Overview

The Lingda LDZH-150KBS and LDZX-100KBS are vertical, full-stainless-steel steam sterilizers engineered for reliable, repeatable moist-heat sterilization under saturated steam conditions at elevated pressure and temperature. These units operate on the fundamental principle of thermal inactivation—utilizing pressurized saturated steam to achieve microbial lethality across a broad spectrum of vegetative bacteria, spores, viruses, and fungi. Designed to meet national medical-grade sterilization standards equivalent to ISO 17665-1 and GB 8599–2008 (Chinese standard for steam sterilizers), they deliver validated sterilization cycles compliant with Class B (EN 13060) or N-type (non-porous load only) applications. The sterilizers are suitable for routine decontamination and terminal sterilization of wrapped/unwrapped instruments, surgical drapes, glassware, culture media, saline solutions, and laboratory consumables in environments requiring GLP-aligned documentation and operational traceability.

Key Features

• Manual lever-actuated quick-opening door mechanism ensures secure sealing and rapid access without hydraulic or pneumatic assistance—ideal for labs prioritizing mechanical simplicity and long-term maintenance predictability.
• Microprocessor-based control system with real-time digital display (LED/LCD) provides continuous monitoring of chamber temperature, pressure, elapsed time, and cycle phase.
• Programmable sterilization parameters: temperature adjustable from 50 °C to 134 °C; exposure time configurable from 0 to 99 hours—enabling customization for heat-labile media (e.g., agar plates at 121 °C/15 min) or high-bioburden loads (e.g., 134 °C/3–5 min).
• Integrated safety interlocks prevent door opening during pressurized operation; automatic pressure release activates within 0.145–0.208 MPa range to safeguard structural integrity.
• Fully AISI 304 stainless steel construction—including chamber, jacket, and outer casing—ensures corrosion resistance, cleanability, and compatibility with repeated steam exposure and cleaning agents used in regulated lab environments.
• Acoustic end-of-cycle alert followed by automatic power cutoff enhances operational discipline and reduces risk of post-cycle handling errors.

Sample Compatibility & Compliance

These sterilizers accommodate both porous and non-porous loads, including autoclavable metal instruments, textile packs, PET/PP containers, borosilicate glassware, and liquid-filled vessels (with appropriate venting protocols). While LDZH-series models support gravity-displacement and pre-vacuum-assisted cycles (where applicable per configuration), LDZX-100KBS is optimized for standard gravity displacement—suitable for non-packaged items and liquids. All units comply with GB/T 30690–2014 (sterilizer performance testing), and their design aligns with essential requirements of ISO 13485:2016 for medical device manufacturers. Optional validation accessories (e.g., thermocouple ports, biological indicator holders) facilitate IQ/OQ/PQ execution in accordance with FDA 21 CFR Part 820 and EU MDR Annex I.

Software & Data Management

The embedded controller supports manual cycle initiation and stores up to 10 user-defined programs. Though not equipped with Ethernet or USB data export, the unit provides timestamped cycle logs visible on the display panel—including start time, setpoint temperature/pressure, actual values, duration, and fault codes. For laboratories requiring electronic record retention, third-party data loggers can be integrated via external PT100 or 4–20 mA interfaces (available upon request). Cycle documentation meets minimum ALCOA+ principles for attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available records—supporting internal audits and regulatory inspections under GLP, GMP, or CAP-accredited workflows.

Applications

• Hospital central sterile supply departments (CSSD) for instrument reprocessing.
• University and industrial microbiology labs performing routine media preparation and glassware sterilization.
• Pharmaceutical R&D facilities sterilizing excipients, buffers, and lab-scale bioreactor components.
• Food safety and agricultural testing labs validating pathogen reduction in sample processing tools.
• Biosafety Level 1 and 2 laboratories requiring validated decontamination of PPE, waste containers, and work surfaces.

FAQ

What sterilization standards do these units conform to?
They comply with GB 8599–2008 and GB/T 30690–2014, and their performance aligns with ISO 17665-1 for moist-heat sterilization process validation.
Can these sterilizers handle liquid loads safely?
Yes—LDZX-100KBS and LDZH-150KBS support liquid cycle modes with slow exhaust and post-sterilization cooling phases to prevent boil-over; recommended maximum fill level is 75% of container volume.
Is third-party validation support available?
Lingda provides technical documentation packages (including factory test reports and material certifications) and collaborates with qualified validation service providers for IQ/OQ/PQ execution.
What maintenance intervals are recommended?
Daily: Chamber inspection, gasket cleaning, drain valve flushing. Quarterly: Safety valve calibration, door seal integrity check. Annually: Full pressure vessel inspection per local regulatory authority guidelines.
Are spare parts and service manuals supplied with purchase?
Yes—standard delivery includes English-language operation manual, electrical schematic, consumables kit (seal ring, filter elements), and access to Lingda’s global distributor network for certified field service.
