Class II Type B2 Biosafety Cabinet Manufacturers in Chennai
Among Class II cabinets, Class II Type B2 cabinets provide the maximum level of protection. With a unique circulation pattern that draws air downward across the work surface and exhausts it via HEPA filters, they safeguard both employees and products. This “total exhaust” design guarantees that all of the air within the cabinet is securely filtered and evacuated. Class II Type B2 cabinets are appropriate for handling dangerous biological agents and volatile chemicals.
