GS Rapidox II™ Furnace

REDOX Measurement is provided as a service to our customers.

Redox Measurements GS Rapidox II™

For those customers who need this type of observation frequently or do not want to disclose the results, we can supply the equipment/machinery.

We also provide all necessary consumables for smooth operation, for example crucibles or sensors.


GS Rapidox II™ furnace can be used for a variety of applications in the glass industry:

  • Batch redox control for the characterization of “unknown” components, such as recycled cullet and filter dust, an aspect of importance to container glass producers

  • Monitoring of the melting process by analysis of scoop samples taken from the melting tank, e.g. during a color change of a container of float glass furnace

  • Evaluation of the samples taken from the feeder and the final glass products; it is important to obtain a stable forming process and to ensure consistent color quality



By means of rapid measurement of oxygen activity with fast response times, wide dynamic range
and high reproducibility GS Rapidox II™ furnace:


  • Reduces waste
  • Increases the use of recycled cullet
  • Filters dust
  • Lowers environmental contamination
  • Optimizes fining processes
  • Minimizes changeover times
  • Decreases energy consumption
