Baker SterilGARD e3 SG404 4-Foot Class II Type A2 Biological Safety Cabinet

Description

Baker SterilGARD e3 SG404 4-Foot Class II Type A2 BSC – Product Highlights

• 44-inch usable work surface accommodates high-throughput workflows including simultaneous multi-flask cell culture, automated liquid handling systems, and multiple ancillary instruments, making the SG404 the standard configuration for labs requiring more workspace than a 3-foot BSC provides without the footprint of a 5- or 6-foot cabinet.
• StediFLOW auto-adjusting airflow technology continuously monitors and compensates for HEPA filter loading across the full filter lifecycle, maintaining verified inflow and downflow velocities without manual recalibration to ensure consistent NSF/ANSI Standard 49-compliant containment performance from installation through end of filter service life.
• Class II Type A2 recirculating design provides personnel, product, and environmental protection for BSL-2 and BSL-3 biological agent handling by exhausting approximately 30% of cabinet air through a HEPA filter back into the room, eliminating the need for a dedicated building exhaust duct under standard biological application conditions.
• UniPressure Preflow Plenum delivers uniform laminar downflow across the entire interior work zone, eliminating turbulent dead zones that compromise sterile conditions in cell culture, tissue culture, microbiological research, and cGMP biological safety cabinet applications requiring consistent aseptic processing performance.
• ReadySAFE low-flow standby mode reduces power consumption to approximately 207 W between active work periods while sustaining HEPA-filtered airflow, and the high-efficiency DC motor and LED lighting system further reduce normal operating consumption to 414–483 W — significantly below conventional biosafety cabinet operating levels.
• Standard utility package includes left and right cable ports, two GFCI outlets, right-side plumbing port, two plugged penetrations, and one vacuum valve for flexible integration of gas lines, liquid handling connections, and other laboratory equipment without additional cabinet modification.
• Optional equipment includes a UV light for surface decontamination between procedures and a FlexAir canopy connection for facilities that require the ability to exhaust cabinet air to a building duct system when working with trace volatile chemicals alongside biological agents — providing installation flexibility not available on standard Type A2 recirculating cabinets.
• One-piece stainless steel work surface with radiused coved corners eliminates seams that harbor biological contaminants and enables rapid decontamination between procedures, supporting stringent cleaning protocols for aseptic processing, compounding, and regulated clean air and containment environments.
• Front-loading HEPA filters, detachable side panels, and diagnostic LED indicators minimize downtime during annual NSF recertification, preventive maintenance, and filter replacement, reducing total cost of ownership across the cabinet’s operational lifespan.
• ARES Scientific is an authorized distributor for Baker, ensuring every SterilGARD e3 SG404 ships as a genuine product backed by a 72-month manufacturer warranty, expert installation support, and Baker-certified annual NSF recertification services.

Frequently Asked Questions – Baker SterilGARD e3 SG404

What is the Baker SterilGARD e3 SG404 and how is it different from the 3-foot SG304?

The Baker SterilGARD e3 SG404 is a 4-foot Class II Type A2 biological safety cabinet that shares the same StediFLOW airflow technology, NSF/ANSI Standard 49 certification, and containment performance as the 3-foot SG304 but provides a significantly larger 44-inch usable work surface — approximately 18 additional inches of interior width — making it the preferred configuration for workflows requiring simultaneous multi-flask cell culture, automated liquid handling systems, or larger equipment setups within a single Class II A2 biological safety cabinet.

What is the FlexAir canopy connection option on the SG404?

The FlexAir canopy connection is an optional accessory that allows the SG404 to be connected to a building exhaust duct system via a canopy (non-sealed) exhaust interface, providing an additional layer of chemical containment when working with small quantities of volatile toxic chemicals alongside biological agents. Unlike a Class II Type B2 total-exhaust cabinet, the SG404 with FlexAir remains a Type A2 recirculating design — the canopy connection supplements rather than replaces the cabinet’s internal HEPA recirculation, and the building exhaust system must be capable of accommodating the required exhaust volume; consult ARES Scientific’s technical team to confirm suitability for your specific application and facility infrastructure.

Does the SterilGARD e3 SG404 require ducted exhaust for standard biological applications?

No — the SG404 operates as a recirculating Type A2 biosafety cabinet and exhausts HEPA-filtered air back into the laboratory without requiring a hard-ducted exhaust connection for standard biological workflows including cell culture, tissue culture, microbiological research, and clinical specimen processing. The optional FlexAir canopy connection is available for facilities that work with trace volatile chemicals and want exhaust flexibility, but it is not required for standard biological containment applications covered by the NSF/ANSI 49 certification.

Is the Baker SterilGARD e3 SG404 NSF/ANSI 49 certified?

Yes — the SG404 meets NSF/ANSI Standard 49 requirements for Class II Type A2 biosafety cabinet design, construction, and performance, providing verified inflow and downflow airflow velocities and HEPA filtration efficiency for safe handling of biological agents at BSL-2 and BSL-3 containment levels. This certification supports the annual recertification programs required by most institutional biosafety committees, regulatory agencies, and accreditation bodies governing research and clinical laboratory operations.

What applications is the Baker SterilGARD e3 SG404 used for?

The SG404 is used across a broad range of laboratory workflows requiring simultaneous personnel, product, and environmental protection, including mammalian and primary cell culture, tissue culture, virological and microbiological research, BSL-2 and BSL-3 infectious agent handling, pharmaceutical aseptic processing and compounding, clinical specimen processing, and vivarium animal transfer procedures — and its 44-inch work surface makes it particularly well suited to high-throughput research settings, biological safety cabinet applications requiring multiple simultaneous equipment setups, and core facility environments where operator ergonomics and workspace area are primary selection criteria.

What optional equipment is available for the SterilGARD e3 SG404?

The SG404 is available with three optional configurations: a UV light for surface decontamination of the work area between procedures; a FlexAir canopy connection that interfaces the cabinet with a building exhaust duct system for applications involving trace volatile chemicals; and a combined UV light with FlexAir canopy connection for facilities requiring both features. A channel stand with casters is also available for laboratories that need to reposition the cabinet between work areas; the standard configuration ships with a fixed channel stand included.
