GeoPyc, a Micromeritics Technology, is an Envelope Density Analyser that rapidly measures the envelope density of porous objects of irregular size and shape. Envelope density or bulk density is the mass of an object divided by its volume where the volume includes that of its pores and small cavities. Envelope density information is useful in characterising catalysts, structural foams, insulators, ceramics, powder metallurgy objects, and other manufactured goods.
GeoPyc follows a unique displacement measurement technique that uses a quasi-fluid called DryFlo which is composed of small, rigid spheres having a high degree of flow-ability. The sample is placed in a bed of Dry Flo which is agitated and gently consolidated about the sample. The GeoPyc collects the displacement data, performs the calculations, and displays or prints the results. The unit also reports percentage porosity and specific pore volume when absolute density information (density excluding pore and small cavity volume obtained from a Micromeritics Accu-Pyc helium pycnometer) is entered.
