Azzota® High performance AAS Atomic Absorption Spectrometer, Flame/Graphite Furnace
  • The A3 Atomic Absorption Spectrometer is a high performance automated instrument designed to meet the requirements of the modern laboratory. Due to its versatility and performance it can be used for a wide range of applications. 
  • Three flame options are available to the user with the Air/Acetylene being the standard configuration. This flame can be used for nearly all standard elements while the N2O/Acetylene and the Air/LPG (natural gas) are available as an option for the more demanding of elements. All three flame configurations offer coded burner for full safety protection. 
  • The graphite head is fixed into the optical path to maximize performance and eliminate drift. The temperature of the transversely heated graphite tube is accurately controlled by means of a precision feedback system. Pyrolytically coated platform tubes are supplied as standard to improve the performance and eliminate many analytical problems associated with this technique. 
  • The flame and graphite furnace can be changed over by a simple selection in versatile AA Win Pro software.
  • One Year Warranty, Lifetime technical support
  • On-site Installation available
  • Accessories available upon request

  • Features 

  • Easy to use, complete software control
  • Integrated safety precautions for user protection
  • Flexible configuration for a wide array of industrial apps
  • Time-saving high-speed analysis
