Bosch offers complete Restricted Access Barrier Systems (RABS) as another Advanced Aseptic Processing solution. The RABS units that we supply are rigid wall enclosures supplied with HEPA filtered unidirectional air to yield an ISO 5 classified space. All air handling equipment is built into the system. Glove port access for personnel is standard with RABS. Glove ports, sleeves and gloves are secured to the walls using well designed and reliable seals. Pre-sterilized equipment and parts are introduced using aseptic procedures including available built in transfer systems and double door airlocks. Doors on the systems are also designed to be opened as necessary for process interventions.

Locations for glove ports, transfer systems and other equipment are determined using full-scale system mockups. This ensures the customer is involved in the process and is fully satisfied with the final product. Glove testing using our GloveFIT system can be seamlessly integrated to ensure compliance with regulatory expectations.

A variation of RABS that Bosch supplies is Closed RABS. These systems consist of fully sealed chambers for use with toxic or highly potent product applications. Personnel protection can be further assured by using negative pressure within the chamber. Filtration systems in the air return system ensures containment of product that may enter the chamber. Manual spray cleaning and clean-in-place systems are available to remove product before opening the chamber for access. These closed RABS systems also offer all of the same features as our standard RABS units.
