The GeoPyc 1360 Envelope Density Analyzer is a revolutionary instrument for rapidly measuring the envelope density of porous objects of irregular size and shape. Particle Size should exceed 2 mm for best results.Envelope density, or bulk density as it is sometimes called, is the mass of an object divided by its volume where the volume includes that of its pore and small cavities.Envelope density information is useful in characterizing catalysts, structural foams, insulators, ceramics, powder metallurgy objects, and other manufactured goods.
The GeoPyc follows a unique displacement measurement technique that uses a quasi-fluid composed of small, rigid spheres having a high degree of flow-ability; we call this medium DryFlo . The sample is placed in a bed of Dry Flo , and the Dry Flo 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.
