12.7 mm Dry Pellet Pressing Die for FTIR KBr Pellet

  • $ 35900


12.7mm Dry Pellet Pressing Die for FTIR KBr Pellet

This dry pellet pressing die is specially designed to create pellets of potassium bromide (KBr) for use in infrared spectroscopy. The die is made from high quality, high hardness tungsten carbide, which ensures a successful compression of both ceramic and metal powders into pellet form. 

Not using enough powdered mixture or excess moisture in KBr can cause the pellets break. For a typical pellet preparation, 400 mg total KBr/sample mixture under a load of 6 to 7 tons press will produce an approximately 1 to 1.5 mm thick pellet. Usually 0.1 to 2% weight to weight of sample to KBr is preferred for pellet pressing. Please use spectroscopic grade KBr or halide salt powder for the best quality pellets. 

In order to grind the desired materials into the correct granularity of powder (from millimeters to microns), we recommend using either our powder processing ball milling products & accessories or our agate mortar & pestle sets.
