Description

Baker SterilGARD e3 SG504 5-Foot Class II Type A2 BSC – Product Highlights

• 56-inch usable work surface supports large-format and multi-operator workflows including concurrent cell culture flask arrays, robotic liquid handling systems, incubators, and additional instruments — making the SG504 the preferred Class II A2 biological safety cabinet configuration for core facility environments, high-throughput biotech labs, and production-scale aseptic processing workflows.
• StediFLOW auto-adjusting airflow technology continuously monitors and compensates for HEPA filter loading throughout the filter’s service life, maintaining NSF/ANSI Standard 49-compliant inflow and downflow velocities without manual recalibration — eliminating the containment performance drift that occurs in conventional biosafety cabinets as filters accumulate particulate load over time.
• Class II Type A2 recirculating design exhausts approximately 30% of cabinet air through a HEPA filter back into the laboratory, providing personnel, product, and environmental protection for BSL-2 and BSL-3 biological agent handling without a dedicated building exhaust duct connection for standard biological applications.
• UniPressure Preflow Plenum delivers uniform laminar downflow across the full 58-inch interior work zone, eliminating dead zones and turbulent air patterns that compromise sterile conditions in cell culture, tissue culture, microbiological, virological, and cGMP biological safety cabinet applications.
• ReadySAFE standby mode reduces power consumption to approximately 219 W while maintaining HEPA-filtered airflow between active work periods, and the high-efficiency DC motor and LED lighting system reduce normal operating draw to 472–598 W — providing meaningful operating cost reductions in continuous-use laboratory environments.
• Standard utility package includes left and right cable ports, two GFCI outlets, right-side plumbing port, two plugged penetrations, and one vacuum valve, supporting flexible integration of gas lines, liquid handling connections, and laboratory instrumentation without additional cabinet modification.
• Optional equipment includes a UV light for work surface decontamination between procedures and a FlexAir canopy connection for facilities requiring a building exhaust duct interface when working with trace volatile chemicals alongside biological agents — with a combined UV light and FlexAir configuration also available for maximum flexibility.
• One-piece stainless steel work surface with radiused coved corners eliminates seams and crevices that harbor biological contamination, enabling thorough surface decontamination between procedures and supporting GLP, GMP, and clean air and containment compliance requirements.
• Front-loading HEPA filters, detachable side panels, and diagnostic LED indicators streamline annual NSF recertification, preventive maintenance, and filter replacement to minimize cabinet downtime and reduce total cost of ownership across the full 72-month warranty period.
• ARES Scientific is an authorized distributor for Baker, ensuring every SterilGARD e3 SG504 ships as a genuine product with full manufacturer warranty, expert installation support, and access to Baker-certified annual NSF recertification services.

Frequently Asked Questions – Baker SterilGARD e3 SG504

What is the Baker SterilGARD e3 SG504 and who is it designed for?

The Baker SterilGARD e3 SG504 is a 5-foot Class II Type A2 biological safety cabinet that provides NSF/ANSI Standard 49-certified personnel, product, and environmental protection for BSL-2 and BSL-3 containment applications, with a 56-inch usable work surface designed for laboratories requiring large-format aseptic workspace — including core facilities, high-throughput biotech and pharmaceutical research labs, production-scale cell culture operations, and multi-operator biological safety cabinet workflows where workspace area and equipment capacity are primary selection criteria.

How does the SG504 differ from the 4-foot SG404?

The SG504 shares the same StediFLOW airflow technology, NSF/ANSI 49 certification, containment classification, electrical service, and optional equipment as the SG404, but provides a 56-inch usable work surface versus the SG404’s 44-inch surface — approximately 12 additional inches of interior width — along with a larger exterior footprint (65¾ in wide vs. 53¾ in) and greater cabinet weight (~714 lb vs. ~582 lb), making it the appropriate choice when workflow throughput, equipment staging requirements, or multi-operator use justify the additional bench space over the 4-foot configuration.

Does the SterilGARD e3 SG504 require ducted exhaust installation?

No — as a Type A2 recirculating biosafety cabinet, the SG504 exhausts HEPA-filtered air back into the laboratory room and does not require a hard-ducted exhaust connection for standard biological applications including cell culture, tissue culture, microbiological research, and clinical specimen processing. The optional FlexAir canopy connection is available for facilities that want a building exhaust interface when working with trace volatile chemicals alongside biological agents, but is not required for standard NSF/ANSI 49-covered containment workflows.

Is the Baker SterilGARD e3 SG504 NSF/ANSI 49 certified?

Yes — the SG504 meets NSF/ANSI Standard 49 requirements for Class II Type A2 biosafety cabinet design, construction, and performance, confirming verified inflow and downflow airflow velocities and HEPA filtration efficiency at ≥99.99% for 0.3 µm particles across both supply and exhaust filters. This certification supports the annual recertification protocols required by institutional biosafety programs, federal regulatory agencies, and laboratory accreditation bodies governing BSL-2 and BSL-3 research operations.

What optional equipment is available for the SterilGARD e3 SG504?

The SG504 is available in three optional configurations beyond the standard cabinet: a UV light for surface decontamination of the work area between procedures; a FlexAir canopy connection that provides a building exhaust duct interface 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, with the standard fixed channel stand included in the base configuration.

What applications is the Baker SterilGARD e3 SG504 best suited for?

The SG504 is well suited for high-throughput mammalian cell culture, primary tissue culture, virological and microbiological research, BSL-2 and BSL-3 infectious agent handling, pharmaceutical aseptic processing, clinical specimen processing, vivarium animal transfer, and Class II A2 biosafety cabinet applications in core facility and production-scale laboratory environments where a 56-inch work surface enables concurrent procedures, multi-instrument staging, and two-operator workflows without the full exterior width of a 6-foot cabinet.
