Isolators are clean air devices providing a complete separation between an aseptic process (hazardous/non-hazardous), the technical personnel, and the surrounding work environment. Isolators are generally used in applications requiring a high degree of protection from external elements or contaminants, and they can serve as alternatives to sophisticated cleanrooms.
Isolators typically feature built-in air filtration systems capable of significantly lowering the particle count in an enclosed area. The relatively compact size of the isolator’s interior makes it easier to clean with gas or vapor sterilizing agents. Isolators can be configured to have either positive or negative pressure relative to the surrounding environment depending on the application. Positive pressure isolators provide product protection against contaminants, hence maintaining sterility; while negative pressure isolators, on the other hand, provide personnel and or environmental protection by containing the hazardous or toxic materials inside the isolator.
