Class III Biological Safety Cabinets Features and Options
Germfree’s Class III Biosafety Cabinets are available with a wide range of options and accessories that can be designed and fitted to meet your exact needs.
Pass-throughs and airlocks can be virtually any size and can be equipped with the following:
Through-wall embeds are equipped with seamless bioseals and gaskets to prevent the ingress and egress of contaminants into or out of the containment zone.
Examples of Through-wall Embeds Include:
Stainless Steel Transport Containers
The U.S. Army’s SCBCOM developed these transport containers to enable a first responder or field collector to safely and securely transport samples containing hazardous chemicals, potential chemical warfare agents, and infectious biological materials. These materials can then be transported from the point of collection to the Laboratory Response Network (LRN), Public Health Lab, or other facilities for analysis. Transport Containers utilize RTP technology to maintain sample containment during transport and transfer. The unit passes military and industrial hazardous sample container tests. Triple packaged samples are contained in a 60 ml primary container, placed in a 500 ml secondary container, and placed within the Stainless Steel Transport Container.
Chemical Dunk Tanks
Chemical dunk tanks are available in a variety of configurations and materials.
Back-Up Power Supply
A back-up power supply system is available for Class III Biosafety Cabinets. These systems are designed to supply necessary power for safe and proper shut-down of equipment in the event of a power failure.
Based on the intended use, Germfree can equip the Class III BSC with round, oval or oversized oval gloveports and wide panel polycarbonate viewing screens on one or both sides.
We offer a range of biosecurity options, including:
Cameras mounted inside Class III Biosafety Cabinets provide additional biosecurity. These allow additional viewers to witness manipulations while monitors inside the glovebox allow the user to review and adjust images prior to sending. The monitors also allow users to observe activity outside of the laboratory. All of the captured audio and video can be recorded internally or remotely to document chain of custody.

Exhaust Filtration Systems
Designed originally for military mobile laboratory applications, the N.B.C. (Nuclear, Biological, and Chemical) filter system unit has been incorporated into Class III BSC for civilian first responders and public health laboratories.
Air that is exhausted from the Class III BSC passes through an exhaust HEPA filter prior to reaching the N.B.C. Filter System Unit. The air then passes through an additional HEPA filter and two MIL Spec Carbon filters prior to discharge to the outside environment.
The air sampling port located between the two Carbon filters is used to monitor any breakthrough from the first filter to determine whether both Carbon filters should be replaced during maintenance. A bubble-tight inlet and exhaust dampers allow for gas decontamination of the HEPA filter and housing prior to filter change. The filter unit is designed with a Bag-Out system for safe removal and disposal of the HEPA and Carbon filters.
The N.B.C. (Nuclear, Biological, and Chemical) filtration system is designed for work in conjunction with the Class III Glovebox but can also be used with other containment equipment. It utilizes redundant HEPA and Carbon filters with a breakthrough monitor placed between the two carbon filters. If desired, the Carbon filters supplied can be Mil Spec ASZM-TEDA. Developed by the U.S. Army to handle chemical weapons, ASZM-TEDA carbon is activated and impregnated carbon specifically for this use.
