Restricted-access barrier systems are more than just a Actual physical barrier. The systems also need cautious dealing with of interfaces, interventions, and material transfers. Processes surrounding the isolator and sanitation have to be tailored and consistently noticed to choose complete advantage of RABS.
Managed airflow is a crucial element of RABS systems. Air filtration and sterilization systems are employed to keep up a sterile environment within the enclosure, stopping the entry of contaminants in the course of the production course of action.
Currently, almost two hundred many years later on and with around 2200 business production lines in regular cleanrooms in operation worldwide (1), we nonetheless handle the introduction on the human ingredient as we search for the very best feasible level of sterility and the prevention of cross contamination in aseptic production.
Equally isolator and RABS present Bodily barriers to shield the product or service as well as the employee from likely dangerous substances. They tend to be made use of in the course of critical procedures to safeguard the merchandise from feasible organisms and particulate contamination.
Originally, technological problems and discussions on sterilization validation or decontamination from the isolator posed worries.
RABS and C-RABS purpose is to supply a controlled surroundings with high amount of defense to transfer and procedure elements or products by way of little openings (termed “mouse holes”) made to enter and exit this kind of equipments.
Exclusive aseptic-transfer methods and answers can be used with RABS, and they supply Considerably operational flexibility. Sanitation processes tend to be more complex in the RABS system than in a standard sterile area. Moreover, equally as in isolation systems, glove dealing with and assembly within the gloveports in RABS are more intricate due to sterility demands.
The proper interface methods and the right managing are hugely sizeable. RABS enable extended creation runs, but impose additional limits than isolation systems. The definition draft very carefully states:

RABS could be categorised as possibly Energetic or passive systems. A passive RABS doesn't have its own air recirculation, filtering, or conditioning. Its superior-purity air provide comes from the cleanroom.
One or multiple EC impellers provide 20 air adjustments for every minute of HEPA filtered air to your ISO Class five inside. Objects could be released to your transfer chamber and later on handed website on a sliding tray by way of a door into the get the job done chamber the place the operator can perform compounding by way of a set of connected gloves. Capable to adapt to every pharmacy’s workflow, one can configure the device Along with the transfer chamber over the still left or correct aspect and alternatives like an IV bar with six hooks inside or possibly a waste disposal system beneath.
You will find key differentiators in between isolators and RABS. Every single system has special validation systems and levels of leak tightness. Moreover, RABS should be contained inside an aseptic zone, whereas an isolator would not should be within an aseptic area.
These points are the main main reasons why manufacturing corporations are beginning to lean far more to the use of isolators within their procedures.
