Agate Pestle + Mortar Grind Solid Samples - Specac

Agate Mortar and Pestles are the ideal tool for manually grinding solid samples with an appropriate mull agent (such as KBr powder, Nujol, or Fluorolube) in preparation for mull FTIR transmission analysis, diffuse reflectance, and KBr pellet press applications. Pure agate is non-absorbing in the infrared spectroscopic region.
