The AccuPyc II TEC – The Temperature-Controlled Gas Displacement Pycnometer Solution

The AccuPyc II Series are fast, fully automatic gas displacement pycnometers that provide high-speed, high-precision volume measurements and true density calculations on a wide variety of powers, solids, and slurries. Micromeritics has added a versatile temperature-control solution to this series with the introduction of the AccuPyc II TEC.

Gas pycnometry is recognized as one of the most reliable techniques for obtaining true, absolute, skeletal, and apparent volume and density. However, materials subjected to changing temperature may have a direct effect on their volume, thereby affecting accurate density determination. The AccuPyc II TEC is an excellent option for use with temperature sensitive or viscous samples where environmental temperature cannot be adequately controlled.

The AccuPyc II TEC features a Peltier thermoelectric device to deliver temperature stability and accurate temperature control from 15 to 36 oC, adjustable in 0.1 oC increments.

Available in stand-alone models with sample chamber sizes of 10-cm3 and 100-cm3, the instrument also comes in an analysis module version for remote operation when utilizing an AccuPyc II control module.

Optional software can also enable the instrument to determine the density of semi-solid bituminous materials. With this TEC software solution, data can be closely correlated to those obtained with ASTM Test Method D70-09, but with much faster specific gravity, volume, and density results. This option includes disposable sample cups to limit contamination and minimize cleaning of the sample chamber between analyses.
