Advanced in vitro exposure systems.

For the exposure to liquid aerosols


This system is specifically designed for dose-controlled and spatially uniform deposition of liquid aerosols on cells cultured at the air/liquid interface. The aerosol is applied for a short time of approx. 3 – 4 minutes.

VITROCELL® Cloud System Phase 1

Phase 1 - Emission of Cloud

VITROCELL® Cloud System Phase 2

Phase 2 - Homogeneous Mixing

VITROCELL® Cloud System Phase 3

Phase 3 - Gravitational Settling

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.
