What are the key features of an ISO 5 isolator?
ISO 5 isolators are designed with specific features to maintain a sterile environment and facilitate safe and efficient sterility testing procedures. These isolators are equipped with high-efficiency particulate air (HEPA) filters, which remove 99.97% of particles 0.3 microns or larger from the air. The isolator's design includes a sealed chamber with glove ports, allowing operators to manipulate materials without compromising the sterile environment.
Key features of ISO 5 isolators include:
- HEPA filtration systems
- Positive pressure differential
- Continuous airflow monitoring
- Sealed chamber design
- Glove ports for material manipulation
One of the most critical aspects of ISO 5 isolators is their ability to maintain a positive pressure differential between the isolator chamber and the surrounding environment. This pressure difference prevents the ingress of contaminants from the outside, ensuring the integrity of the sterile space within.
ISO 5 isolators must maintain a positive pressure differential of at least 10-15 Pascal (Pa) to prevent contamination from the external environment.
| Feature | Specification |
|---|---|
| HEPA Filter Efficiency | 99.97% for particles ≥ 0.3 μm |
| Pressure Differential | 10-15 Pa (minimum) |

The design and implementation of these features ensure that QUALIA ISO 5 isolators provide a reliable and efficient environment for sterility testing, meeting the stringent requirements of regulatory bodies and industry standards.
How does an ISO 5 isolator maintain sterility?
Maintaining sterility within an ISO 5 isolator is a complex process that relies on multiple systems working in harmony. The primary mechanism for maintaining sterility is the continuous flow of HEPA-filtered air through the isolator chamber. This unidirectional airflow sweeps away any potential contaminants and maintains a constant supply of clean air.
The sterility maintenance process involves:
- Continuous HEPA filtration of incoming air
- Unidirectional airflow patterns
- Regular integrity testing of the isolator system
- Strict decontamination procedures before and after use
In addition to the airflow system, ISO 5 isolators employ rigorous decontamination procedures. Before each use, the isolator is typically sterilized using methods such as vaporized hydrogen peroxide (VHP) or chlorine dioxide gas. These sterilization processes ensure that the interior surfaces of the isolator are free from microbial contamination.
The sterilization efficacy of ISO 5 isolators must be validated to achieve a sterility assurance level (SAL) of at least 10^-6, meaning a probability of not more than one viable microorganism in one million sterilized items.
| Sterility Maintenance Factor | Description |
|---|---|
| Air Change Rate | 240-480 times per hour |
| HEPA Filter Efficiency | 99.97% at 0.3 μm |
| Sterilization Method | VHP or Chlorine Dioxide Gas |
| Sterility Assurance Level | 10^-6 |
The ISO 5 isolator systems are designed to provide a robust barrier against contamination, ensuring the integrity of sterility testing procedures and the safety of both products and operators.
