When using the Continuous Flow Exposure Systems, cell cultures are exposed to a continuous flow of gases, complex mixtures or particles. Only this exposure principle is suitable for aerosols containing a gas and particle phase.
The advantage of this method is a longer exposure duration. In the VITROCELL® standard systems exposure durations are normally up to 6 hours, whereas the VITROCELL® Automated Exposure Stations make exposures for 24 hours possible.
Continuous Flow Exposure is used for gases, chemicals or materials which are available in larger quantitities (several g) under a constant delivery. When scarce and very expensive materials need to tested, this method is less suitable. We recommend in these cases Single Droplet Sedimentation or Dry Powder Systems.
