� Containment connections

� Containment isolator

� C-RABS



� Split valve

� High containment split valve

� RTP port

� Liner


Containment connections: split valves

� Simple operating principle

� Made up of two parts:

- active part sealed on the process equipment

- passive part sealed on the container

� Concept: once docked, the two parts then operate as one

disc and together can be opened to allow product transfer

� Residual powder


Containment connections: split valves

couplingdocking dischargingactive part

(cont’d)

passive part


Containment connections: high containment split valves

� Concept: same as standard split valve

� High containement assurance (inflatable sealing, vacuum, ...)

� High cleaning capability (air purge, CIP, ...)

� Optimized balance between GMP and HSE requirements


Containment connections: high containment split valves (cont’d)


Containment connections: RTP ports

� For the transfer of both sterile and/or toxic products

� Made up of two parts:

- the fixed part (alpha port)mounted on the wall of the isolator

- the mobile part (beta port)sealed to the rigid or flexible container

� Concept:

- 2 sealings meeting at a point

- 4 elements mutually shielding each other’s faces, locked

together by rotation of beta port


Containment connections: RTP ports(cont’d)

� Sampling options


Containment isolator: main features

� Tight enclosure in negative pressure

� Exhaust system through double HEPA filter

� Exhaust system able to increase the fan speed in case of serious

damage on the glove (break of the glove). Safety inflow velocity

throught the glove-hole of 0,7 m/s

� Interlocked closed doors during production

� Use of gloves to access any working area needed to be reached

by operator during production

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


RABS: main features

� Rigid wall enclosure

� Unidirectional air flow system providing an ISO 5 environment

� Surrounding room classification ISO 7 minimum in operation

� Interlocked closed doors during production

� Use of gloves to access any working area needed to be reached by operator during production

� Aseptic transfer of materials


RABS: tipes

� Passive RABS

� Active RABS

� Open RABS

� Closed RABS

� Air handling system

� Independent unit

� Integrated with room HVAC

� Containment grade

� Air exhausted into the production room

� Aseptic application

� Air recirculated and exhausted outside

� Containment application


Passive RABS

�air handling unit integrated with

room HVAC

� possibility to additionally protect

an area outside


Active RABS

� air handling unit independent

from room HVAC

� outside area protection possible

as option

� possibility to specifically treat the

air in the RABS


Air inlet

filtro HEPAfiltro HEPA

“Filter Fan Unit”“Filter Fan Unit”

da HVAC + filtro HEPAda HVAC + filtro HEPA


Open RABS

� air exhausted in the room

� no possibility to create

differential pressure (+ or -)

AIR FROM THE ROOM


Closed RABS

� air not exhausted into the

production room but

recirculated and exhausted

outside (return duct and exhaust

duct)

� proper for powder handling

(depending on OEL)

� possibility to create differential

pressure (+ or -)

� possibility to specifically treat the

air in the RABS


RABS: application

� O-RABS

� Aseptic process

� C-RABS

� Barrier to avoid cross-contamination for liquid and solids with medium

potency

� Containment barrier for high potent liquid with capability to generate

aerosol

� Containment barrier for medium potent solids with not very powdery

operations
