All Logic+ Type C1 biosafety
cabinets meet the airflow
requirements of ANSI/NSF Standard
49. The Chem-Zone
TM
(center work
surface) air is filtered and exhausted
via a remote building exhaust
system, while the inflow and outer
work surface air is filtered and
recirculated. All Type C1 Logic+
biosafety cabinets feature
intrinsically safe designs, jacketing
contaminated positive pressure
areas with negative pressure zones.
