Micromeritics has added a versatile temperature-control solution to its AccuPyc II Series of fast, fully automatic gas displacement pycnometers series with the introduction of the AccuPyc II TEC.
Gas pycnometry is recognised as one of the most reliable techniques for obtaining true, absolute, skeletal, and apparent volume and density.
However, subjecting materials to changing temperature may affect on their volume and accurate density determination. The AccuPyc II TEC is suitable for use with temperature sensitive or viscous samples where environmental temperature cannot be adequately controlled.
It 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 utilising an AccuPyc II control module.
Optional software can enable the instrument to determine the density of semi-solid bituminous materials.
With the TEC software solution, data can be closely correlated to those obtained with ASTM Test Method D70-09, but with faster specific gravity, volume, and density results.
The option includes disposable sample cups to limit contamination and minimise cleaning of the sample chamber between analyses.
