Purair Bio Class II, Type A2 biological safety cabinets from Air Science, Fort Myers, Fla, provide a primary containment work area for life science research, cell culture processing, and other applications that require mitigation of cross-contamination on the work surface, and protection of the user, the work product, and the environment.
Biosafety in the laboratory is critical when work involves infectious diseases and toxins, as well as in cell and tissue culturing, where product contamination must be avoided. Protection of personnel against lab-acquired infections can also be achieved by reducing potential exposure to droplets or splashes, preventing contaminants from escaping the work area.
A biological safety cabinet provides a safe laboratory workspace using optimal airflow design combined with an integrated high-efficiency particulate air (HEPA) filtration system. Room air is drawn in through the intake grille on the front of the unit, and is then directed under the work surface to the top of the cabinet, where it passes through a HEPA filter.
Negative pressure is created inside the cabinet, resulting in a primary containment work area, while HEPA filtration supplies clean air to the work surface in a vertical laminar flow pattern. The airflow patterns provide an optimal air curtain on the front opening, maintaining personnel and product protection. The exhaust HEPA filter traps biohazardous particles prior to the air being exhausted back into the laboratory, preserving environmental protection.
