Universal aerosol generator 7811

GRIMM 7811
Universal aerosol generator

For generation of aerosols from liquids, suspensions and solutions. 


Functionality: Aerosol generation by atomization of liquids

  • Generation of aerosols from all kinds of liquids, suspensions and solutions e.g. NaCl, DEHS, PSL
  • Integrated pumps
  • No compressed air needed
  • Independently adjustable air flows (nebulizer flow and dry air flow)
  • Flexible, user-selectable aerosol generation
  • Easy-to-use
  • Smart cartridge storage
  • Suitable for small liquid volumes
  • Calibration and testing
  • Fundamental aerosol research
  • Inhalation and toxicology studies
  • Filter testing
  • Technical data
