Labconco 4′ Cell Logic Class II Type B2 Biological Safety Cabinet Model 343481102
Scope-Ready with Temp-Zone™, Service Fixture, Vacu-Pass™ Portals & Base Stand
The Labconco Cell Logic Class II Type B2 Biological Safety Cabinet is engineered to provide maximum personnel, product, and environmental protection when working with hazardous biological particulates, including applications requiring BSL-1 through BSL-4 containment.
Class II Type B2 biosafety cabinets—also known as 100% Exhaust or Total Exhaust BSCs—maintain a minimum average inflow velocity of 100 feet per minute (fpm) through the sash opening and require a dedicated exhaust system with a remote blower. All inflow and downflow air is HEPA-filtered and exhausted from the laboratory, making this cabinet appropriate for volatile chemical use as an adjunct to microbiological work.
Designed specifically for cell research, Cell Logic Type B2 cabinets feature a modified sash compatible with microscopy and a Temp-Zone™ temperature-controlled work area to help maintain cell viability during sensitive procedures.
