Micromeritics Accupyc II 1340 TEC gas displacement pycnometer

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 the series with the introduction of the AccuPyc II TEC.

Gas pycnometry is a reliable technique 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 suitable for use with temperature-sensitive or viscous samples where environmental temperature cannot be adequately controlled.

The product features a Peltier thermoelectric device to deliver temperature stability and accurate temperature control from 15 to 36°C, adjustable in 0.1°C increments. Available in stand-alone models with sample chamber sizes of 10 and 100 cm³, the instrument also comes in an analysis module version for remote operation when utilising an AccuPyc II control module.

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