Zealway GF54SA Vertical Fully Automatic Steam Sterilizer

Overview

The Zealway GF54SA is a vertically oriented, fully automatic steam sterilizer engineered for precision, safety, and regulatory compliance in research laboratories, clinical diagnostics, pharmaceutical QC labs, and biotechnology facilities. It operates on the principle of saturated steam under controlled pressure and temperature to achieve microbial inactivation—primarily through protein denaturation and nucleic acid disruption. With a validated working range of 105–138 °C at up to 0.30 MPa (43.5 psi) maximum working pressure—and a certified design pressure of 0.42 MPa—the GF54SA meets the mechanical and thermal requirements defined in YY 1007, China’s national standard for vertical steam sterilizers. Its 54 L stainless-steel chamber (Φ320 × 726 mm) supports diverse load configurations while maintaining uniform heat distribution and rapid steam penetration. The unit integrates real-time saturation monitoring to verify cold air removal prior to sterilization, ensuring consistent delivery of saturated steam—a critical prerequisite for effective lethality (F₀) validation.

Key Features

• 7-inch full-color capacitive touchscreen interface with glove-compatible operation and bilingual (English/Chinese) display—designed for intuitive workflow navigation and audit-ready parameter logging.
• Automated cycle memory system storing up to 99 user-defined sterilization protocols, including configurable hold times, ramp rates, and post-cycle drying parameters.
• Integrated saturation assurance algorithm that dynamically monitors exhaust phase performance and validates steam quality before initiating the sterilization dwell period.
• Biological safety–compliant exhaust management: all vented steam and condensate are thermally treated or filtered to eliminate viable microorganisms prior to release.
• Self-cleaning function with programmable intervals (e.g., daily or per-cycle), utilizing high-temperature steam flush to minimize biofilm accumulation and mineral scaling.
• Optimized condenser design achieving near-zero visible steam emission during exhaust—reducing ambient humidity impact and improving lab HVAC efficiency.
• Chamber constructed from medical-grade SUS316 stainless steel, offering superior corrosion resistance against chloride-rich media, saline solutions, and repeated thermal cycling.
• Six-stage programmable exhaust control enables precise cooling rate modulation—critical for heat-labile loads such as agar media or pre-packaged instruments.

Sample Compatibility & Compliance

The GF54SA accommodates a broad spectrum of sterilizable materials: wrapped surgical instruments, porous textile packs, liquid media (including culture broths and buffers), rubber tubing, glassware, and regulated biohazard waste. Load configuration adheres to ISO 17665-1 (Moist Heat Sterilization) guidelines for load mapping and thermocouple placement. All sterilization cycles comply with YY 1007 mechanical and performance verification criteria—including temperature uniformity (±1 °C), pressure stability (±0.01 MPa), and B&D (Bowie-Dick) test integration for porous load qualification. Optional traceability modules support FDA 21 CFR Part 11–compliant electronic signatures and ALCOA+ data integrity principles when interfaced with LIMS or SCADA platforms.

Software & Data Management

The embedded control firmware supports optional Ethernet/Wi-Fi connectivity for remote monitoring via Zealway’s proprietary sterilization management software. Cycle logs—including time-stamped temperature/pressure curves, door status, exhaust profiles, and alarm history—are stored internally (≥10,000 cycles) and exportable in CSV or PDF format. When integrated into enterprise systems (e.g., LabVantage LIMS or Siemens Desigo CC), the GF54SA transmits real-time operational metadata—including F₀ accumulation, cycle pass/fail status, and maintenance alerts—to centralized dashboards. Audit trails record all parameter modifications, user logins, and cycle initiations with immutable timestamps—meeting GLP/GMP documentation requirements for quality-controlled environments.

Applications

• Terminal sterilization of reusable surgical tools and dental handpieces in hospital SPD departments.
• Pre-sterilization of cell culture consumables (pipette tips, flasks, filters) in academic and industrial life science labs.
• Media preparation workflows requiring validated depyrogenation of liquid growth media (e.g., LB, DMEM, MRS).
• Biocontainment support: decontamination of BSL-2 waste streams using extended 134 °C cycles with vacuum-assisted exhaust.
• Pharmaceutical manufacturing: sterilization of excipient containers and process equipment components under cGMP-aligned SOPs.
• Regulatory submissions: generation of IQ/OQ/PQ documentation packages compliant with ISO 13485 and ICH Q5A.
