Baker SterilGARD e3 SG304 3-Foot Class II Type A2 Biological Safety Cabinet

Description

Baker SterilGARD e3 SG304 3-Foot Class II Type A2 BSC – Product Highlights

• StediFLOW auto-adjusting airflow technology continuously monitors inflow and downflow velocities and automatically compensates for HEPA filter loading, maintaining NSF/ANSI Standard 49-compliant containment performance throughout the filter’s operational lifespan without manual recalibration or service intervention.
• Class II Type A2 recirculating design provides simultaneous personnel, product, and environmental protection for BSL-2 and BSL-3 biological agents, exhausting HEPA-filtered air back into the room and eliminating the need for a dedicated building exhaust duct connection for standard biological applications.
• UniPressure Preflow Plenum delivers uniform downflow air velocity across the full interior work zone, eliminating turbulent dead zones that compromise aseptic conditions in cell culture, tissue culture, microbiological research, and cGMP biological safety cabinet applications.
• Momentum air curtain technology creates a continuous inward airflow barrier at the work opening that captures aerosolized biological agents before they can escape the containment zone, supporting personnel safety and culture integrity for infectious agent handling in accordance with NSF/ANSI 49 requirements.
• ReadySAFE low-flow standby mode reduces operating amperage to 1.1 A between active work periods while maintaining HEPA-filtered airflow, and the high-efficiency DC motor and full LED lighting system together lower total power consumption to approximately 126 W in standby — significantly below conventional biosafety cabinet operating costs.
• Standard utility package includes left and right cable ports, two GFCI outlets, right-side plumbing port, two plugged penetrations, and one vacuum valve, providing flexible integration for liquid handling systems, gas lines, and other laboratory equipment without additional cabinet modifications; a UV light option is available for surface decontamination between procedures.
• One-piece stainless steel work surface with radiused coved corners eliminates seams and crevices that harbor biological contaminants, enabling rapid decontamination between procedures and supporting stringent cleaning protocols required for aseptic processing, compounding, and regulated clean air and containment environments.
• Front-loading HEPA filters and detachable side panels simplify annual NSF recertification, routine preventive maintenance, and filter replacement to minimize downtime and reduce total cost of ownership throughout the cabinet’s operational lifespan.
• Channel stand is included for ergonomic, stable bench-height placement; an optional channel stand with casters is available for laboratories requiring cabinet repositioning between work areas.
• ARES Scientific is an authorized distributor for Baker, ensuring every SterilGARD e3 SG304 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 SG304

What is the Baker SterilGARD e3 SG304 and what does it do?

The Baker SterilGARD e3 SG304 is a 3-foot Class II Type A2 biological safety cabinet (BSC) that provides simultaneous personnel, product, and environmental protection when working with biological agents requiring BSL-2 or BSL-3 containment. It uses HEPA-filtered laminar downflow air and a momentum air curtain at the work opening to prevent aerosolized pathogens from escaping the work zone, making it suitable for cell culture, tissue culture, microbiological research, clinical specimen processing, and pharmaceutical aseptic processing workflows.

What is the difference between a Class II Type A2 and a Class II Type B2 biological safety cabinet?

A Class II Type A2 cabinet like the SG304 is a recirculating design that exhausts approximately 30% of its air through a HEPA filter back into the room and recirculates the remaining 70%, which means it does not require a hard-ducted exhaust connection for standard biological applications. A Class II Type B2 biological safety cabinet exhausts 100% of its air through a dedicated building exhaust duct and is required when working with appreciable quantities of volatile toxic chemicals or radionuclides alongside biological agents. The SG304 is the appropriate choice for the majority of cell culture, microbiology, and aseptic compounding workflows that do not involve volatile hazardous chemicals.

Does the SterilGARD e3 SG304 require ducted exhaust installation?

No — as a Type A2 recirculating biosafety cabinet, the SG304 exhausts HEPA-filtered air back into the laboratory and does not require a dedicated exhaust duct for standard biological applications, making it significantly less expensive to install than ducted cabinets and compatible with laboratory spaces where building exhaust infrastructure is unavailable. If your application involves small quantities of volatile toxic chemicals used in combination with biological agents, a canopy exhaust connection to a building exhaust system may be recommended; consult ARES Scientific’s technical team to confirm the appropriate configuration for your specific workflow.

Is the Baker SterilGARD e3 SG304 NSF/ANSI 49 certified?

Yes — the SterilGARD e3 SG304 meets NSF/ANSI Standard 49, the governing U.S. standard for biosafety cabinet design, construction, and performance, confirming verified inflow and downflow airflow velocities, HEPA filtration efficiency, and containment integrity for BSL-2 and BSL-3 biological agent handling. NSF certification also supports the annual recertification requirements maintained by most institutional biosafety programs, regulatory agencies, and accredited laboratory facilities.

What optional equipment is available for the SterilGARD e3 SG304?

The SG304 is available with an optional UV light for surface decontamination of the work area between procedures, and an optional channel stand with casters is available for laboratories that need to reposition the cabinet between workstations. The standard configuration ships with a fixed channel stand included; both the standard and caster stand options position the cabinet at ergonomic bench working height.

What applications is the Baker SterilGARD e3 SG304 used for?

The SG304 is used across a broad range of laboratory workflows requiring simultaneous personnel and product protection, including mammalian cell culture, primary tissue culture, microbiological and virological research, clinical specimen processing, BSL-2 and BSL-3 infectious agent handling, pharmaceutical aseptic processing and compounding, and vivarium animal transfer procedures. Its compact 3-foot footprint makes it well suited to smaller laboratory spaces, satellite labs, and bench alcoves where larger Class II A2 biological safety cabinets cannot be accommodated.
