Cytotoxic Glovebox Isolator

What is the Cytotoxic Glovebox Isolator?

A cytotoxic glovebox isolator is a sealed negative-pressure enclosure with glove ports for hazardous drug handling. It gives the highest operator protection for potent or volatile agents and for high aerosol loads.

Overview

The glovebox isolator seals the work zone entirely, with long gloves bonded to the front panel and interlocked transfer ports for materials and waste. Interior pressure is negative relative to the room, and supply air is HEPA filtered; exhaust passes HEPA filtration, and usually a second stage or carbon filter for volatile agents, before a dedicated duct. Drug aerosols cannot reach the operator because there is no open front, and the sealed enclosure also protects the environment. Airflow is unidirectional over the work zone at 0.45 m/s to support ISO 5 conditions for aseptic compounding. The design suits potent compounds, volatile agents and operations with high aerosol risk, at the cost of reduced dexterity and a fixed working height. Leak tightness and airflow are both verified at certification.

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 bonded long gloves
• Negative pressure with HEPA supply and exhaust
• Carbon or second stage for volatile agents
• Interlocked transfer ports for materials and waste
• ISO 5 unidirectional airflow at 0.45 m/s
• Leak tightness verified at certification

What are the technical specifications?

A typical cytotoxic glovebox isolator configuration offers device type of Cytotoxic glovebox isolator, interior pressure of Negative, 20–100 Pa below room, work zone class of ISO 5, downflow velocity of 0.45 m/s ± 20 %, exhaust filtration of HEPA plus carbon optional and recirculation of None, total exhaust. 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 Cytotoxic Glovebox Isolator is used in potent hazardous drug handling, volatile agent compounding, high-aerosol-risk operations and research and phase trials. 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 Cytotoxic Glovebox Isolator?

Choose a glovebox isolator for potent or volatile agents and high aerosol risk where no open front is acceptable. Confirm glove reach and transfer arrangements for the workflow. RFQ: agent list, activity, glove layout, exhaust filtration, transfer needs and leak test standard.

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.
