Compounding Aseptic Containment Isolator

What is the Compounding Aseptic Containment Isolator?

A Compounding Aseptic Containment Isolator is a sealed glovebox for sterile hazardous drug compounding. It gives high operator protection and an ISO 5 work zone with no direct operator contact during preparation.

Overview

The isolator is a sealed enclosure with glove ports and a HEPA-filtered unidirectional airflow of 0.45 m/s over the work zone, giving ISO 5 conditions for sterile compounding. All air is HEPA filtered on supply, and exhaust passes HEPA filtration to a dedicated duct, usually with no recirculation. The interior is held at negative pressure so leaks draw inward, and drugs and materials pass through an interlocked transfer hatch or a sterile pass-through. Working height is lower than an open cabinet, and the operator relies on gloves and sleeve length, so tasks are planned for reach. The isolator reduces operator exposure and the need for a full gowning room, and it can be installed in a controlled area rather than a cleanroom depending on the pharmacy's risk assessment and local rules.

How does it work?

Cytotoxic cabinets combine the airflow of a Class II biosafety cabinet with a design that keeps hazardous drug particles and vapours away from the operator and out of the room. Room air enters at the front grille, forming an air curtain across the opening, and HEPA-filtered air flows downward over the work zone to protect the preparation. Exhaust is HEPA filtered, and the cabinet is typically operated without recirculation into the work zone, with all exhaust sent to a dedicated duct. Many designs hold the work surface at negative pressure and use a split or closed front so drug aerosols cannot escape. Some pharmacy units use sealed glove ports, giving isolator-style containment with no direct operator contact. Surfaces are smooth stainless steel or plastic for frequent decontamination, and the cabinet is a classified environment for aseptic operations. Certification covers HEPA integrity, airflow and containment testing.

What are the key features?

• Sealed enclosure with glove ports
• ISO 5 unidirectional airflow at 0.45 m/s
• HEPA supply and exhaust, no recirculation
• Negative pressure with inward leakage
• Interlocked transfer hatch or sterile pass-through
• Reduced gowning requirement

What are the technical specifications?

A typical compounding aseptic containment isolator configuration offers device type of Compounding aseptic containment isolator, work zone class of ISO 5, downflow velocity of 0.45 m/s ± 20 %, recirculation of 0 %, total exhaust, HEPA grade of H14 supply and exhaust and interior pressure of Negative, 20–100 Pa below room. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Compounding Aseptic Containment Isolator is used in sterile hazardous drug compounding, high-volume pharmacy preparation, centralised cytotoxic services and hospital and oncology pharmacies. Across the wider Cytotoxic Cabinets class, laboratories also deploy it for antineoplastic drug compounding, hospital pharmacy aseptic preparation and hazardous drug dose preparation.

Which standards and certifications apply?

Relevant standards and methods include EN 12469 (biosafety cabinets), NSF/ANSI 49 (biosafety cabinetry), USP <800> (hazardous drugs handling in healthcare settings), USP <797> (pharmaceutical compounding, sterile preparations), ISO 14644-1 (cleanroom classification) and EU GMP Annex 1 (sterile manufacturing). Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Place the cabinet in a controlled area with correct room pressure relationships, commonly a negative-pressure buffer room, and away from doors and air diffusers. Change gloves and sleeves on a defined schedule and inspect them for pinholes, since operator protection depends on intact barrier and airflow. Decontaminate the work surface and interior after every session and use a closed-system transfer device where required. Verify HEPA integrity, inflow and containment at installation and at least annually, and after relocation or filter change. Do not exceed the maximum drug volume or use unapproved agents that would overwhelm the exhaust. Manage waste, sharps and spill kits according to the hazardous drug procedure, and keep a log of certification and decontamination.

How do I select the right Compounding Aseptic Containment Isolator?

Choose an isolator when the highest operator protection and a compact pharmacy footprint are priorities and glove access is acceptable. Confirm ISO 5 performance, transfer method and room requirements. RFQ: drug list and volume, glove layout, transfer needs, exhaust and certification.

How does it compare with other Cytotoxic Cabinets variants?

Select the cabinet from the hazardous drug list, the required dose accuracy and the pharmacy's aseptic requirements. Use a Class II Type B2 cytotoxic cabinet with 100 % dedicated exhaust when volatile hazardous drugs are prepared. Choose a Compounding Aseptic Containment Isolator where the highest operator protection is needed and full isolation is acceptable, since glove access reduces dexterity. A Type A2 cytotoxic cabinet with canopy exhaust suits lower-risk drugs when recirculation is limited and local rules allow it. Confirm compatibility with USP <800> and USP <797> requirements, the pharmacy's risk assessment and any local rules on where the cabinet is placed, including a negative-pressure buffer room. Verify certification, plan for HEPA leak and containment testing, and specify the transfer method for drugs and waste.
