Micromeritics AccuPyc II 1340 Series pycnometers are available through Particle & Surface Sciences. The company claims the fully automatic pycnometers provide rapid, precise volume measurements and density calculations on a wide variety of powders, solids and slurry shaving volumes from 0.01 to 350 cm3. The instruments claim to accurately complete most sample analyses in less than 3 mins.
Suitable for analysing a limited amount of material, Micromeritics’ AccuPyc II 1340 1 cm3 gas displacement pycnometer performs fully automatic, high-speed, high-precision volume measurements and density calculations on a variety of powders and solids. The pycnometer has a design that allows the volume of small amounts of sample to be accurately detected and measured with reliability to within a fraction of a microlitre.
Its manifold design uses reliable, high-precision valves that seal securely so that small leaks do not contribute to variability of results. High-compression, minimum-volume seals around the pressure transducer minimise helium storage and leakage. This shortens the time to complete a run cycle and reduces the development of temperature gradients that may otherwise compromise results. The pycnometer also features a low-noise transducer amplifier that can result in faster equilibration.
The instrument can be operated with a keypad or an optional Windows interface that provides good 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, percent solids content and total pore volume reports.
For users requiring 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.
