Micromeritics's Accupyc II 1340 1cm3 gas displacement pycnometer from Particle and Surface Sciences performs fully automatic volume measurements and density calculations on various powders and solids.
The Accupyc II features improvements in design that allow the volume of small amounts of sample to be accurately detected and measured with enhanced reliability to within a fraction of a microlitre.
A manifold design is said to utilise high-reliability, high-precision valves that seal more securely so that small leaks do not contribute to the variability of results.
High-compression, minimum-volume seals around the pressure transducer are intended to minimise helium storage and leakage.
This shortens the time to complete a run cycle and eliminates the development of temperature gradients that may otherwise compromise results.
The Accupyc II 1340 1cm3 also features an ultra-low noise transducer amplifier that results in faster equilibration.
The instrument can be operated with a keypad or an optional Windows interface, which provides a reporting and archiving capability.
Both versions include direct sample mass input from a balance and cycle-based displacement volume reporting.
The Windows interface also includes time-based pressure equilibration, per cent solids content and total pore volume reports.
For high throughput, an integrated control and analysis module can control up to five additional external-analysis modules of the same or different volume capacities.
A glove-box model is also available for analyses in applications where the control module and analysis module must be in separate environments.
The Accupyc may be operated in English, French, German, Italian or Spanish.
