The Claisse M4 is a standard in sample preparation by fusion. The M4 is a three-position automatic gas instrument that prepares glass disks for XRF analysis as well as solutions for AA and ICP analysis. It is very useful as it can process a broad range of samples such as:

  • Polymers, catalysts
  • Sulfides
  • Cement, slag, ceramic, silica, glass, carbonates
  • Mining and geological samples
  • Bauxites, fluorides
  • Pure metals, ferroalloys, and other alloys

Improved analytical results can be acquired by using the M4 fusion instrument as it is known for its fast and excellent homogenization of the melt. Its uniform heating leads to extremely reproducible results and all its fusion parameters can be changed so as to obtain the preferred fusion conditions.

The M4 fusion instrument is also very cost-effective as it has low maintenance and operation costs. It ensures a quick ROI.

Other Benefits of Using the M4 Fusion Instrument

  • Automatic spark ignition
  • Easy to install and to operate
  • Optimal agitation by rotation while inclined
  • No calibration, compressed air or oxygen needed
