RABS: definition
Restricted
Access
Barrier
System
“Restricted Access Barrier System (RABS) is
an advanced aseptic processing system that
can be utilized in many applications in a fill-
finish area. RABS provides an enclosed
environment to reduce the risk of contamination
to product, containers, closures, and product
contact surfaces compared to the risks
associated with conventional cleanroom
operations.” ISPE definition, August
2005
