BIOLOGICAL SAFETY CABINET (CLASS II TYPE B2) “MAC” MSW-164 (B2)

Inclusive of all taxes

The BIOLOGICAL SAFETY CABINET (CLASS II TYPE B2) “MAC” MSW-164 (B2) by MACRO SCIENTIFIC WORKS PVT LTD is a high-performance biological safety cabinet designed for laboratories requiring stringent contamination control and user protection. This Class II Type B2 cabinet ensures near 100% exhaust of contaminated air by operating at negative pressure around all biologically contaminated parts, thereby eliminating air recirculation within the work area. Constructed with a durable stainless steel (SS-304) internal working table and a cold-rolled steel powder-coated exterior, it offers robustness and long-term reliability. The cabinet channels room air through a top-mounted blower and HEPA supply filter, delivering vertical unidirectional airflow into the workspace. Air is pulled through perforated front and rear grilles and exhausted completely outside without any recirculation, connected to an external exhaust system, guaranteeing maximum safety. The HEPA filtration exceeds EU-14 standards with over 99.999% efficiency for particulates of 0.3 microns, accompanied by a EU-4 class pre-filter. Designed for ergonomic use, it features a sloped front window with transparent toughened glass sash that counterbalances for smooth operation and provides clear visibility, ensuring operator comfort and safety. Additional functionality includes lockable heavy tubular stands, UV and fluorescent light interlocks, easy-to-maintain removable covers for filters and blowers, an electric power socket for equipment, and a liquid spill trough for quick cleanup. With an internal work area of 600x610x675 mm, this model, STERIMAX-2 (B2-CRC), is optimized for safe handling and containment of biological materials in high-risk lab environments, making it an ideal solution for hospitals, research institutes, and pharmaceutical industries.
