Zealway GL60SA Vertical Autoclave System

Overview

The Zealway GL60SA Vertical Autoclave System is a fully automated, Class B (EN 13060-compliant) steam sterilizer engineered for precision, safety, and regulatory readiness in academic, clinical, and industrial laboratory environments. It operates on the validated principle of saturated steam under controlled pressure and temperature—leveraging the thermodynamic properties of moist heat to achieve microbial inactivation of vegetative bacteria, spores, viruses, and prions. With a 60 L cylindrical chamber (Φ400 × 505 mm), the GL60SA supports gravity displacement and vacuum-assisted air removal cycles, enabling reliable sterilization of porous loads, wrapped instruments, liquids, and heat-labile materials. Its design adheres to ISO 17665-1 (sterilization of health care products) and incorporates structural and functional safeguards aligned with ASME BPVC Section VIII Division 1 and PED 2014/68/EU requirements.

Key Features

• 7-inch full-color capacitive touchscreen interface with intuitive icon-driven navigation—eliminates multi-layer menu traversal and reduces operator training time.
• Embedded memory system stores up to 99 user-defined cycle protocols with timestamped parameter logs, supporting traceability and routine validation workflows.
• Real-time saturation monitoring via integrated pressure–temperature correlation algorithms ensures consistent delivery of saturated steam; automatic cold-air purge verification confirms chamber evacuation prior to sterilization phase.
• Modular connectivity architecture supports optional integration with LIMS (e.g., Thermo Fisher SampleManager, LabVantage), SCADA platforms, and Zealway’s proprietary sterilization management software—enabling remote cycle initiation, live parameter streaming, and audit-ready electronic records.
• Biosafety-engineered exhaust path includes HEPA-filtered venting and condensate containment, meeting WHO and CDC biosafety level 2 (BSL-2) discharge guidelines for infectious waste processing.
• Onboard automatic chamber rinse cycle—programmable for post-cycle or scheduled execution—reduces biofilm accumulation and minimizes manual maintenance intervals.
• High-efficiency coaxial condenser achieves near-zero visible steam emission during exhaust, complying with ISO 14644-1 Class 8 cleanroom-compatible exhaust standards.

Sample Compatibility & Compliance

The GL60SA accommodates diverse load types including wrapped surgical kits, unwrapped metal instruments, glassware, liquid media (with anti-boil-over control), rubber tubing, agar plates, and regulated biohazardous waste bags. Cycle profiles conform to EN 285 (large steam sterilizers), EN 13060 (small steam sterilizers), and ANSI/AAMI ST79:2017. All firmware and data handling modules are designed for compatibility with FDA 21 CFR Part 11 requirements—including electronic signature support, audit trail generation (cycle start/stop, parameter changes, user login/logout), and immutable record retention. The system supports IQ/OQ documentation packages and is pre-qualified for GMP/GLP environments requiring periodic requalification per ISO 13485 and ISO 9001 frameworks.

Software & Data Management

Firmware version 3.2+ provides encrypted local storage of ≥10,000 complete cycle records with embedded metadata (operator ID, chamber temp/pressure curves, phase durations, alarm history). Optional cloud-based analytics dashboard delivers trend analysis for cycle consistency, thermal penetration deviation, and preventive maintenance alerts. Data export formats include CSV, PDF (with digital signature), and XML for seamless ingestion into enterprise quality systems. Audit trails meet ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and are exportable without administrative override.

Applications

• Sterilization of reusable surgical and diagnostic instruments in hospital central sterile supply departments (CSSD).
• Preparation of microbiological growth media and buffer solutions in pharmaceutical QC labs.
• Inactivation of Category B biological waste per UN3291 and local biosafety regulations.
• Validation of autoclave performance for ISO 11134 and ISO 11140-2 chemical indicator compliance testing.
• Support of ISO 14644-1 classified cleanroom operations where steam exhaust integrity is critical.
• Research applications requiring reproducible thermal challenge studies (e.g., D-value determination, lethality mapping).

FAQ

What sterilization standards does the GL60SA comply with?
It meets EN 13060:2022 (Class B small steam sterilizers), ISO 17665-1:2019, and ANSI/AAMI ST79:2017. Full compliance documentation is provided with installation qualification (IQ) and operational qualification (OQ) kits.
Can the GL60SA be integrated into an existing LIMS or MES infrastructure?
Yes—via Ethernet TCP/IP or RS485 Modbus RTU, with configurable OPC UA support available upon request for advanced manufacturing execution system (MES) interoperability.
Is the automatic chamber rinse function validated for residue removal?
Rinse efficacy has been verified using ATP bioluminescence assays per CLSI EP21-A and ISO 15883-5, demonstrating ≤10 CFU residual microbial load after three consecutive rinse cycles.
How does the six-stage exhaust control enhance process safety?
Programmable exhaust rates (from slow-cool to rapid depressurization) prevent thermal shock to heat-sensitive loads and mitigate boil-over risk in liquid cycles—each mode includes real-time pressure ramp rate limiting and interlock-triggered hold-on-deviation logic.
Does the system support remote diagnostics and firmware updates?
Remote secure access (SSH/TLS-encrypted) enables authorized service engineers to perform diagnostics, calibrate sensors, and deploy firmware patches—subject to customer-configured network policies and role-based access controls.
