The Baker SterilGARD III Advance SG603TX is a durable machine built not just with functionality and user comfort in mind but with longevity.
A quick primer in case you’re not familiar with the difference between biosafety cabinet classifications. Close to 90% of the units sold on an annual basis and in use now are designated as Class II, Type A2 or Class II Type A/B3. Class II Type A2 cabinets meet requirements for protection of product, personnel and the environment and are widely used to clinical, research, hospital, life science, and pharmaceutical settings. All BSCs with Class II designation have front access with inward airflow, HEPA filtered vertical airflow in the work area, and HEPA-filtered recirculated air.
Class II Type B2 cabinets, also known as total exhaust bio safety cabinets, are used in applications that require protection from hazardous particulates, vapors and gases. These models are almost hybrids of a Class II Type A2 model and a chemical fume hood. Toxicology labs often utilize Class II Type B2 biosafety cabinets, as well as labs working with tissue culturing of possibly infectious subjects, antineoplastic drugs, genetic material, asbestos, volatile toxic chemicals, radionuclides or any substance that generates hazardous airborne particulates or where chemical effluent is present. These units must be hard ducted to a dedicated exhaust system and/or remote blower motor to discharge 100% of the filtered air from the laboratory.
Like other biosafety cabinets, when the total exhaust Baker SG603TX is in operation room air enters the front access opening of the cabinet (i.e. the raised glass sash) at a minimum of 100 FPM then enters the front work surface perforation. The cabinet down flow blower draws room air in at the top of the cabinet and pushes it into the down flow plenum and through the supply HEPA filter. Most of the HEPA filtered down flow air passes through a diffuser but some of the air is directed down the back of the viewscreen creating a high velocity air curtain at the front access opening. The HEPA filtered down flow air in the work area splits at the work surface. Some of the air enters the rear work area perforation while the remainder of the air enters the front work surface perforation. The air is pulled through the drain pan area, up the rear and side wall plenums, through the exhaust HEPA filter and out through the 12” exhaust collar at the top of the cabinet.
Before purchasing a total exhaust bio safety cabinet, talk to your facilities management team or HVAC technician. Because of the hard ducting and external ventilation requirements modifications to the building may be required for installation. Because of the risk that contaminated air will flow back into the laboratory in the event of a ventilation failure operators will need to install a monitor to gauge the exhaust flow when the BSC is in use.
The Baker SterilGARD SG603, the SterilchemGARD SG603TX features a 10° tilt to the glass sash viewing screen and a padded armrest, both of which contribute to overall comfort and ergonomic benefit of users. The membrane switch pad is clearly labeled and typically at eye level (depending on installation height and height of users, of course).
Like all Baker products, the SG603TX is durable and efficiently designed. And while you can always call American Instrument Exchange with questions about refurbished lab equipment you’ve purchased from us or plan to purchase from us, tech support at The Baker Company provides is always superb and the staff is knowledgeable, polite, and patient. In short, like all Baker products, we give the SG603TX a hearty thumbs up.
