Skin Exposure Auxiliary Equipment Dose Monitoring Racks & Carts Dilution Dose Supply Exposure Systems The system comes with a choice of 3 types of vibrating mesh nebulizers having droplet MMAD ranges of : ○ 2.5 – 4.0 µm ○ 2.5 – 6.0 µm ○ 4.0 – 6.0 µm Recommended nebulisation volumes are 200 µl. So the device is par ticularly suitable for testing whenever small quantitities of testing materials are available. Different choices of nebulizers Af ter pipetting the suspension, exposure to the cell cultures takes place in two steps, each with three phases: How the Vitrocell ® Cloud works Phase 1 Emission Of Cloud Step 1 Clean Air Control Step 2 Test Aerosol Phase 2 Homogeneous Mixing Phase 3 Gravitational Settling ○ Integrated controller for aerosol generator ○ Optional integrated microbalance controller ○ Defined experiment recipes ○ Automatisation of the experiment by nebulization time or by user-defined volume ○ Output rate database for nebulizers ○ Heating system ○ Optional PowerVent function: evacuation of potentially residual aerosols via vacuum pump ○ Designed for virus research, screening of inhaled drugs and toxicity testing of inhaled substances such as chemicals or nanoparticles Features 63
