The VITROCELL® Cloud can be used for aerosols generated from liquids and suspensions. Possible fields of application are screening for inhaled drugs and toxicity testing of inhaled substances including nanoparticle suspensions. There is a choice among 4 options of Aeroneb® ­nebulizers:

  • 4.0 – 6.0 µm
  • 2.5 – 6.0 µm
  • 2.5 – 4.0 µm
  • 10 µm (special version)

The Cloud aerosol chamber is made of Polycarbonate.


  • Exposure system for liquid aerosols
