Envelope Density Analyzer

Translated information:

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.

Brochure

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 Dry Flo . 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.

The analyzer is operated from a full character-set keypad. Data acquisition and reporting are fully automated for convenient incorporation in LIMS or other data concentrating systems.

A variety of sample chambers is available to accommodate a wide range of sample sizes. After the analysis, a light shaking or dusting completely removes the Dry Flo so the samples can be reused or retested. The GeoPyc has multiple operating modes including full blank, computed blank, and reference solid calibration with variance, which allows you to optimize speed and accuracy for your individual needs. During analysis, indications of progress and preliminary results make it possible to track what is occurring. Sample-specific information can be entered and the report generated in English, German, Italian, or Spanish.

T.A.P. Density Option

When equipped with the T.A.P. Density option, the GeoPyc measures the packing volume and calculates the bulk density of granular and powdered samples under a wide range of compaction conditions.

To determine T.A.P. density, the sample chamber is rotated and agitated while a precise specified force is applied to the sample. A force transducer measures the consolidation force in Newtons and the distance over which the consolidation piston and plunger travel is measured in steps. The user specifies the force applied and the number of consolidations per analysis. The GeoPyc averages the measurements from each consolidation and automatically calculates volume and density, and reports the results in cm³ and g/cm³. The GeoPyc T.A.P. density option obtains precise results comparable to conventional tap density analyzers, only it does it faster, quieter, and with greater reproducibility.

A Note About 32- and 64-Bit Windows and Micromeritics' Software
Micromeritics products are designed to operate in most Microsoft Windows environments. However, more current versions of Microsoft Windows, specifically the 64-bit version of Windows 7, lack some of the services once offered by Microsoft. Because of this, Micromeritics applications will not operate with 64-bit operating systems. Micromeritics software applications are directly compatible with 32-bit version operating systems only. In cases where a 64-bit operating system may be corporate-required or essential for running other software programs, Virtual PC software and a 32-bit operating system should be installed on the host computer (64 bit) as a guest operating system. This will allow proper installation and operation of the Micromeritics application.
