Understanding Isolator
What Are Isolator?
An isolator is an enclosed system that separates the inside environment from the outside. It consists of a transparent front panel, glove ports, air filtration systems, and various monitoring and control mechanisms. Isolators are typically made from stainless steel or other materials that are easy to clean and sterilize. They provide a physical barrier that protects both the products and operators from potential contamination.
Types of Isolator
Isolators come in different types, each tailored to specific applications and requirements. The common types include:
- Pharmaceutical Isolator: Designed for aseptic processing and handling of pharmaceutical products, ensuring product protection and sterility.
- Containment Isolator: Engineered to handle hazardous materials and protect operators from exposure to toxic substances.
- Biocontainment Isolator: Specifically designed for working with biological agents, preventing their release into the surrounding environment.
- Research Isolator: Used in research laboratories to provide a controlled environment for experiments and handling sensitive materials.
How Isolator Work
Airflow and Filtration Systems
Isolators maintain a controlled environment by employing advanced airflow and filtration systems. HEPA (High-Efficiency Particulate Air) filters are used to remove particles and microorganisms from the air, ensuring a sterile environment. The airflow within the isolator is carefully managed to maintain positive or negative pressure, depending on the application requirements.
Glove Port Systems
Isolators feature glove ports that allow operators to perform tasks inside the enclosure while maintaining the isolation. These glove ports are equipped with gloves made from materials compatible with the process or application. Operators can manipulate the products or equipment within the isolator without compromising sterility.
Gas Decontamination
To ensure complete decontamination, isolators are equipped with gas decontamination systems. These systems use sterilizing agents such as hydrogen peroxide vapor or ozone to eliminate any residual contaminants present within the isolator. Gas decontamination provides a reliable and efficient method for maintaining the integrity of the isolator environment.
