Aseptic Process & Sterility Test Isolators:

Aseptic Filling Machine Isolator:

Designed to enclose the filling, stoppering, and capping operations of a powder or liquid filling machine while providing an aseptic environment for the process. It features unidirectional airflow, hinged, "easy-lift" window panels and a special "mouse hole" for the exit of filled vials.

Sterility Test Isolators: 

Sterility-testing isolators are used to perform trials on both in-process and finished products.  They are intended to replace traditional sterility-testing practices and to reduce "false-positives" and subsequent wasted product, as a result of flawed sterility testing.  Reducing the number of false-positive results in a sterility-testing isolator depends on the efficacy of the isolator bio-decontamination.  Bio-decontamination of an isolator and its contents eliminates or reduces the number of biological contaminants in the isolator, reducing the risk of sample contamination and a false-positive result.  A chemical sterilant, typically vaporized hydrogen peroxide (VHP), is used in the bio-decontamination process.  VHP bio-decontamination is accomplished by connecting the isolator to a commercially available VHP generator, which pretreats the interior of the isolator and then introduces VHP into the isolator's interior.  After sufficient VHP dwell time (validated duration), the residual VHP is
removed from the isolator interior during an aeration stage.
