Baker SterilGARD III Advance SG403M Overview
The Baker SterilGARD III Advance SG403M is a modified 4-foot biosafety cabinet engineered for laboratory environments requiring contamination control, sterile airflow, and customized workflow integration. Baker SterilGARD cabinets have long been recognized throughout biotechnology laboratories, pharmaceutical facilities, hospital laboratories, academic research institutions, and cleanroom environments for their durable construction, stable airflow performance, and long-term containment reliability.
Unlike standard production biosafety cabinet models, the SG403M designation typically indicates that the cabinet has been modified from its original factory configuration to support a specific laboratory workflow or application. Depending on the original installation, modifications may include customized interior layouts, integrated accessories, animal handling configurations, equipment pass-throughs, modified work surfaces, altered cabinetry, or workflow-specific containment adaptations.
Please note that this specific unit has been modified with a circular dumping port located in the center of the work surface. Laboratories evaluating this cabinet should confirm that the dumping port configuration is compatible with their intended workflow, containment procedures, and certification requirements prior to installation. Depending on the original application, this type of modification may have been used for powder handling, waste transfer, specialized process integration, or custom laboratory procedures.
The SG403M operates using a HEPA-filtered airflow system designed to maintain sterile working conditions while supporting containment protection for biological workflows. Features may include pressure-resistant plenums, stainless steel interior construction, fluorescent lighting, airflow monitoring systems, removable work trays, ergonomic sash positioning, and heavy-duty welded-steel cabinet construction depending on the specific configuration of the unit.
Many SG403M cabinets were configured with Baker’s hydraulic adjustable stand system, allowing operators to raise or lower the cabinet working height to improve ergonomics during extended laboratory procedures. Adjustable-height biosafety cabinets may help reduce operator fatigue during repetitive tissue culture, microbiology, pharmaceutical, or animal handling workflows involving multiple users.
Because modified biosafety cabinets may vary significantly from standard factory configurations, buyers should carefully review photographs, dimensions, electrical requirements, and interior layout details prior to installation.
Laboratories outfitting complete containment workflows may also be interested in refurbished CO2 incubators, ultra-low freezers, autoclaves, and water baths available through American Instrument Exchange.
