Claire® total models are particularly suitable for work in combination with volatile toxic compounds or also with radioactive labelled substances and viruses particles. They represent a special device type for the handling of biological and chemical hazardous substances under aseptic, low particle conditions. The concept uses an air conveyance system without recirculation into the work space. In the working space a uniform laminar flow is generated. A series of high-efficiency cartridge filters as the main filter stage retain particulate matter from the total airflow which is removed by a fixed exhaust air system.
