PHCbi brand's 1.8 cu.ft (50L) Cell-IQ stackable CO2 incubator is designed to help deliver a contamination-free environment. CO2 quickly returns to setpoint after door openings. Its compact design allows the units to be double or triple stacked for maximized footprint. A streamlined interior optimizes space and reduces contamination risk while improving ease of maintenance when combined with passive decontamination controls such as the patented inCu-saFe® interior.
