Sterility Test Isolator
A stable Grade A (ISO 5) environment for pharmacopoeia sterility testing — protecting the sample from false positives and the operator from the tested product, with a reserved VHP generator port for 6-log decontamination.

The Fenggu Sterility Test Isolator delivers a stable Grade A (ISO 5) environment for pharmacopoeia sterility testing, protecting both the sample from false positives and the operator from the tested product. A rigid stainless-steel platform combined with a transparent enclosure maintains positive or negative pressure as required, while a VHP cycle, via a reserved generator port, achieves a 6-log sporicidal reduction of the chamber and all exposed surfaces before testing begins. The design supports both membrane-filtration and direct-inoculation methods per pharmacopoeia requirements.
A combined main chamber and transfer chamber allow material to enter without breaking sterility; each can also be operated independently. The standard work chamber has 4 front-mounted gloves, with single- or double-sided configurations and additional transfer-chamber ports available to suit the application.
Key Features
- Grade A / ISO 5 (Class 100) unidirectional (laminar) airflow environment with sustained positive pressure
- Reserved port for a vaporized hydrogen peroxide (VHP) generator, achieving 6-log sporicidal reduction of the chamber air and exposed surfaces (subject to validation)
- Supports both membrane-filtration and direct-inoculation sterility test methods
- Main chamber plus independent transfer chamber for sterile material entry (custom sizes available)
- SUS304 exterior / SUS316L internal chamber, 4 front-mounted gloves standard, CSM chemical-resistant sleeves
- Siemens PLC and touchscreen, pressure-loss alarm
- Electronic data storage and export; software compliant with FDA 21 CFR Part 11; validation per USP <1208>
