GeoPyc 1360 Micromeritics

The GeoPyc 1360 Envelope Density Analyzer rapidly measures the envelope density of porous objects of irregular size and shape by using a unique displacement measurement technique. Envelope density is the mass of an object divided by its volume where the volume includes that of its pores and small cavities.

The instrument is based on the Archimedes principal and utilizes a quasi-fluid displacement medium composed of nonhazardous microspheres having a high degree of flowability. This novel approach eliminates the need for oils, solvents, and mercury that are traditionally required as a displacement medium. Micromeritics’ patented DryFlo displacement material does not wet the sample or fill its external or internal pores. A light shaking or dusting completely removes the DryFlo after analysis; therefore the roller compaction ribbon can be reused or retested. The GeoPyc collects the displacement data, performs the calculations, and displays or prints the results. A variety of sample chambers is available to accommodate a wide range of sample sizes.
