Combustion Tube Conversion Kit for Leco® CS844/CS744

Elemental Microanalysis offers a conversion kit, E4356, that adapts the Leco® CS844 and CS744 analysers to be able to use a much lower cost combustion tube (C4356) than the Leco® equivalent tube.

Customers need only purchase this easy-to-use kit once, to adapt the analyser, and then the combustion tube C4356 from Elemental Microanalysis can be used, instead of the Leco® equivalent, each time a new combustion tube is required.

 Benefits to customers of E4356 conversion kit 

  • Saves time because the lower O-ring needn't be removed during replacement.
  • Allows more precise vertical alignment.
  • Tube remains in lower tube ring during multiple cleanings, or until replaced.
  • Easily installed, and can quickly be returned to original configuration.
  • Considerable cost savings over the life of the CS844/744.
