UltraPyc-1200e for Gas Pycnometry
The UltraPyc-1200e is a fully automated gas pycnometer, for the measurement of volume and density of powders, granular materials, and solid objects. Typical applications include:
- porous materials such as catalysts and activated carbons
- pharmaceuticals and excipients
- foods (raw, refined and end products)
- ceramics and refractory materials
- geological samples (soils, rocks, sediments)
- building materials (concrete, cement)
- polymers and composites
For cellular foam materials, the specially adapted UltraFoam-1200e version is available. For small samples(<4.25cm3), as in typical pharmaceutical applications, the micro-UltraPyc allows the highest precision measurements.
Key features:
- Accuracy: Careful thermal design and the use of high quality sensors assures precise and repeatable measurements.
- Ease of use: Measurements are controlled from the front panel or from a remote computer. Each sample is given a unique identification which is recorded in the results report, along with the operator identifier.
- Versatility: The full analysis protocol can be programmed, including purge mode and duration, measurement configuration, number of repeats and end criteria. A single protocol can be repeated for multiple samples, and saved protocols can be reloaded for later runs.
- Connectivity: Measurement reports are accessible from a connected PC, via remote network access, or saved directly to a USB key connected to one of the built-in USB ports.
- Calibration: A set of NIST tracable calibration spheres is supplied with every instrument. The built-in calibration procedure requires user intervention only to load the appropriate Stainless Steel sphere.
- Multiple purging methods: Continuous flow, pulsed, vacuum outgassing (with optional vacuum pump).
- Gases: Nitrogen, Helium or SF6 are recommended. Other non-corrosive gases may be used for special applications.
- Programmable target pressure: Allows to adapt the maximum pressure for sensitive samples.
- Temperature Control: as an option, the UltraPyc can be configured for connection to a recirculating water bath, permitting measurements at specified temperature(s). This is particularly useful for samples with a large coefficient of thermal expansion.
Standard Sample cell volumes for the UltraPyc-1200e
The UltraPyc-1200e is supplied as standard with three different sizes of cell. Additional cells are available, as shown in the table below.
| Sample Cell Sizes (approximate dimensions) | Nominal Volume | Internal Diameter | Internal Depth |
| (approximate dimensions) | |||
| Standard sample cells | 135 cm3 | 49 mm | 75 mm |
| 50 cm3 | 40 mm | 39 mm | |
| 10 cm3 | 24 mm | 23 mm | |
| Optional micro cell | 4.25 cm3 | 15 mm | 24 mm |
| Optional meso cell | 1.75 cm3 | 13 mm | 13 mm |
| Optional nano cell | 0.25 cm3 | 8 mm | 6.5 mm |
For applications where only small samples are available, the Micro-UltraPyc gives an enhanced sensitivity.
Some related possibilities include:
- PentaPyc-5200e: a multiple sample version of the Ultrapyc-1200e, for high throughput applications.
- UltraFoam-1200e and PentaFoam for characterisation of cellular foam materials.
