LFGI (Laminar Flow Glovebox / Isolator)

The Laminar Flow Glovebox/Isolator provides the ultimate in product and personnel protection. Germfree's LFGI functions as a Compounding Aseptic Containment Isolator (CACI) while operating under strong negative pressure to meet NIOSH recommendations. Additionally, the unit functions as a Compounding Aseptic Isolator (CAI) under positive pressure to meet USP 797 regulations. The operator is provided with a complete barrier from the materials being manipulated by working with a highly ergonomic glove system.

The ultimate in product and personnel protection for sterile compounding and USP 797 compliance.

The Laminar Flow Glovebox/Isolator (LFGI) uses HEPA (High Efficiency Particulate Air) filters to provide the highest level of operator and product protection. The supply HEPA filter provides laminar flow air which bathes the entire work area. The exhaust HEPA filter handles all air exiting the Laminar Flow Glovebox/Isolator. Additionally, there are two HEPA filters located inside the HEPA Purge airlock that filter the purged air. All filters are rated to remove particulates and aerosols 0.3 micron in size with a minimum efficiency of 99.99%. These filters are even more effective at removing particulates both larger and smaller than 0.3 microns.

The Laminar Flow Glovebox/Isolator provides personnel and product protection from particulates, dust, powders and aerosols. Microbiological particulates and aerosols, with the possible exception of Prions, are also removed. Operator and product protection from gas and fumes are NOT provided by HEPA filtration, but limited protection from gas and fumes can be provided by venting or ducting. In accordance with the NIOSH alert on the handling of hazardous drugs, the LFGI can be configured for no recirculation and total exhaust of all air exiting the work area.

The LFGI is constructed of high quality all welded stainless steel with a pharmaceutical grade finish. The unit incorporates an integrated manual height-adjusting stand with locking cleanroom grade casters. The ergonomic, stainless steel sliding tray inside the airlock pulls into the work area, eliminating reaching strains. Further, the stainless steel interior work area trays slide over one another and are removable. This facilitates easy cleanup under the work deck. The extra large oval gloveports incorporate a two-part sleeve/glove system that allows for the use of most types and sizes of commercially available gloves. Glove changes can be made while maintaining containment, furthering personnel protection.

The fluorescent light housing is externally mounted to provide optimum lighting in the work area. The Acrylic viewing panel is encased in a stainless steel frame and set at an angle to reduce glare and enhance operator comfort. The LFGI's system for waste and sharps removal has seals to maintain work area containment. A fully adjustable shelf is included to accommodate most commercially available wide-mouth or hinged-top sharps collectors.

The LFGI Series of barrier isolators meet or exceed ISO 14644-1 for Class 5 air quality. Each LFGI undergoes rigorous physical testing before shipping to assure the unit meets all performance requirements. It is required that independent certification be performed before use.

Compounding Aseptic Containment Isolators:
USP 797 Regulations for Compounded Sterile Preparations

USP 797 provided the first official and enforceable requirements for preparing CSPs -Compound Sterile Preparations. USP 797 is the U.S. Pharmacopeia's (USP) Revised General Chapter <797> for Pharmaceutical Compounding Sterile Preparations. According to the organization these requirements set “practice standards to help ensure that compounded sterile preparations are of high quality”. Chapter <797> fundamentally changed the way that facilities that prepare compounded sterile preparations approach their work.

USP 797 applies to the diverse range of facilities that prepare
Compounded Sterile Preparations

Chapter 797 applies to all facilities that prepare CSPs. This includes hospital and health-system pharmacies that prepare compounded sterile preparations including main hospital pharmacy operations and satellite pharmacy units. USP 797 also applies to clinics, hospital care units as well as other facilities that handle the compounding of sterile preparations. As facilities change their procedures to meet USP 797 requirements, they are finding that barrier isolators can provide an ideal alternative to a more costly cleanroom.

The Food and Drug Administration states that a barrier isolator is: "a decontaminated unit supplied with HEPA filtered air that provides uncompromised continuous isolation of its interior from the external environment, including surrounding cleanroom air and personnel." Installing a Compounding Aseptic Containment Isolator provides cleanroom conditions within a contained workspace. Compounding Aseptic Containment Isolators provide an ISO Class 5 (Class 100) environment for product preparation, with work occurring inside a closed, pressurized work space, accessible only via a sealed gloves system.

General Standards for USP 797 Compounding Aseptic Containment Isolators:

Germfree’s Compounding Aseptic Containment Isolators are an ideal solution for providing a clean work environment in the pharmacy industry when compounding sterile preparations.

As there no true uniform industry standards for manufacturing isolators, there are significant design differences among manufacturers. A well-designed isolator that will significantly reduce microbial contamination should meet a range of minimal standards. Germfree’s LFGI Series meets or exceeds these standards:

Unidirectional airflow showers the work zone with a continuous supply of filtered air that sweeps contaminants out through the air exhaust system.
Negative air pressure maintains containment of hazardous substances within the isolator
Easy to clean and disinfect inside and out
Pass-through system that isolates the interior of the unit from the room when materials are transferred in and out
Made of durable materials (stainless steel, glass, and high-performance, scratch-resistant plastics)
Includes height adjustors to make the work environment ergonomic
