Uses of isolators for aseptic processing are far reaching. The earliest use of aseptic isolators were for sterility testing. Sterility test isolators make up most of aseptic isolator use and are available in many different sizes and configurations. Sterility test isolators do not need to be installed in a classified area. No formal requirement exists for a Grade D environment, but the area should be controlled to allow only trained personnel. The room should also have temperature and humidity control.
