Micromeritics introduces the new AccuPyc II 1340 gas displacement pycnometry system: fast, fully automatic analyzers that provide high-speed, high-precision volume measurements and density calculations on a wide variety of materials. The AccuPyc completes most analyses in less than three minutes with excellent accuracy by using a gas displacement technique to determine absolute density of powders, solids, and slurries having volumes from 0.01cm³ to 350cm³.

The instrument can be operated with a keypad or an optional Windows µ interface that provides exceptional reporting and archiving capabilities. Both versions include direct sample mass input from a balance and cycle-based displacement volume reporting. With the Windows interface, features such as time-based pressure equilibration reporting and additional calculations such as percent solids content and total pore volume are included.

For those who require high throughput, an integrated control and analysis module can control up to five additional external analysis modules. Each module can have a different size sample chamber (1 cm³, 10 cm³, 100 cm³, 350 cm³) providing even more versatility.

A multivolume option allows analysis of a variety of sample sizes in a single analysis module. A temperature-controlled version of the analysis module performs analyses at user-selectable temperatures. The AccuPyc can measure open- and closed-cell foam materials in accordance with ASTM method D 6226 with optional FoamPyc software. A glove box model is also available for analyses in applications where the control module and analysis module must be in separate environments.
