Esco GPPI Sterile Isolation System for Aseptic Testing

Overview

The Esco GPPI Sterile Isolation System is an engineered solution designed specifically for pharmaceutical aseptic testing in compliance with global regulatory frameworks—including the Chinese Pharmacopoeia (ChP), United States Pharmacopeia (USP and ), European Pharmacopoeia (Ph. Eur. 5.1.1), and Japanese Pharmacopoeia (JP XVII). Based on the principle of physical barrier containment and dynamic air management, the GPPI system utilizes positive-pressure unidirectional vertical laminar airflow—validated to ISO 14644-1 Class 5 (ISO Class 5)—to maintain a sterile internal environment during microbiological testing of sterile drug products, APIs, and medical devices. Its stainless-steel construction, seamless welds, and radius-rounded internal corners eliminate cleaning dead zones, satisfying GMP requirements for cleanability and residue control as outlined in Annex 1 (2022 revision) and FDA Guidance for Industry: Sterile Drug Products Produced by Aseptic Processing.

Key Features

• Positive-pressure vertical unidirectional airflow system with ≥99.995% HEPA filtration (EN 1822 H14) and uniform velocity distribution (±15% across working plane), ensuring consistent microbial challenge protection and optimal VHP penetration during decontamination cycles.
• Integrated dry-fog vaporized hydrogen peroxide (VHP) bio-decontamination system employing Esco’s proprietary flash-vaporization technology—capable of achieving ≥6-log reduction of Geobacillus stearothermophilus spores without condensation or filter saturation.
• Leak-tight chamber architecture validated to ≤0.5% vol/hr (per ISO 10648-2:1995), verified via pressure decay testing under both static and dynamic operational conditions.
• Modular, fully customizable design accommodating site-specific spatial constraints, workflow integration, and process-specific accessories—including glove ports, pass-through chambers, integrated particle counters (ISO 21501-4 compliant), and active air samplers (ISO 14698-1).
• GAMP 5-compliant control system with audit trail, electronic signature capability, and data integrity features aligned with FDA 21 CFR Part 11 and EU Annex 11 requirements.

Sample Compatibility & Compliance

The GPPI system supports aseptic handling of diverse sample formats including vials, ampoules, syringes, IV bags, and pre-filled cartridges. All internal surfaces are electropolished 316L stainless steel (Ra ≤ 0.4 µm), compatible with common disinfectants (e.g., 70% IPA, sodium hypochlorite) and VHP exposure. The system meets ISO 14644-1:2015 (Class 5), ISO 14698-1:2003 (biocontamination control), and EN ISO 13485:2016 for medical device manufacturing environments. It is suitable for installation in background environments classified as ISO Class 8 (C-grade) or ISO Class 7 (D-grade), as defined in EU GMP Annex 1.

Software & Data Management

The embedded HMI touchscreen interface enables real-time monitoring of critical parameters: differential pressure (±0.1 Pa resolution), airflow velocity (0.3–0.5 m/s range), VHP concentration (ppm), chamber temperature/humidity, and leak rate trends. All operational logs—including cycle start/stop timestamps, operator IDs, alarm events, and environmental monitoring data—are stored locally with optional export to CSV or PDF. Electronic records include immutable audit trails with time-stamped user actions, role-based access control, and digital signature support for validation documentation. Data archiving complies with ALCOA+ principles and supports retrospective review during regulatory inspections.

Applications

• Aseptic testing of sterile pharmaceuticals per ChP Section 1101, USP , and Ph. Eur. 2.6.1.
• Environmental monitoring during media fill simulations and process validation studies.
• Handling of high-potency compounds requiring operator protection (when operated in dual-mode configuration with optional negative-pressure annex).
• Microbial recovery studies using membrane filtration or direct inoculation methods under controlled ISO Class 5 conditions.
• Supporting QC laboratories in meeting ICH Q5C stability testing requirements for sterility assurance.

FAQ

Does the GPPI system support full-cycle VHP validation per ISO 14644-3?
Yes—the system includes built-in VHP sensors, thermohygrometers, and spore strip holders for mapping and biological indicator placement. Esco provides IQ/OQ/PQ protocol templates and on-site cycle development services.
Can the GPPI be integrated with existing LIMS or MES platforms?
Yes—via configurable Modbus TCP or OPC UA interfaces; custom API integration is available upon request.
What maintenance intervals are recommended for HEPA filters and VHP generator components?
HEPA filters require integrity testing every 6 months (DOP/PAO scan); VHP nozzles and vaporizers undergo preventive maintenance annually, with calibration traceable to NIST standards.
Is training provided for operators and maintenance personnel?
Yes—Esco delivers comprehensive GMP-aligned training covering operation, decontamination protocols, routine checks, troubleshooting, and documentation practices, including hands-on sessions using full-scale wooden mock-ups.
Are spare parts and consumables available regionally?
Yes—all critical wear items—including gloves, gaskets, and VHP reagent cartridges—are stocked and distributed through Esco’s authorized service hubs in Asia, Europe, and North America.
