A size selective inlet separates dif ferent fractions of aerosol according to the installed nozzle plate. The Inlet is adjustable to PM1, PM2,5 and PM10. Inlet with particle separation The base module accepts up to 6 cell culture inserts. Each cell culture compartment has an independent media reservoir. A transparent control window facilitates the external monitoring of media levels. The temperature is controlled by means of a water bath; therefore an additional incubator is not required during the experiment. The temperature for each module is individually monitored. The base module is made of electropolished stainless steel. It is autoclavable at 121° C (250° F) for 20 min. Exposure modules The aerosol is guided into the central reactor of the system where it is humidified if needed. Distribution to the modules via isokinetic sampling probes enables high reproducibility and uniformity of results. Isokinetic sampling system The aerosol inlet stream flows through specifically shaped inlets which are optimized for electrostatic deposition. They are made of stainless steel with VITROGLIDE surface treatment . The stainless steel / VITROGLIDE inlets are specifically designed for the work with nanoparticles. The aerosol flow rate is controlled by mass flow controllers with data recording by the central data management system. Aerosol exposure top 84
