BULKINSPECTOR Gas pycnometer PYC 130-A
high precision, for the determination of the true density of solids & bulk solids
With the BULKINSPECTOR, the first fully automatic gas pycnometer in the world, weighing and volume determination are performed automatically in the instrument – therefore no manual intervention is necessary during the measurement.
Determine the true density (also called skeletal density or pure density) of solids & bulk materials and analyze them in terms of purity & porosity.

Usability and advanced functionality
The pycnometer is controlled via a mobile control unit (tablet), which is included in the scope of delivery.
After opening the app, you are presented with a user-friendly interface with a modern design for operating the device. Through this interface, you can set and manage formulas for different samples. You also have the ability to manage and export measurement logs, as well as customize the basic settings of the instrument. Depending on the user level, some of these functions are password protected.
You can also access the operating instructions via the tablet. If necessary, you can order the required spare and wear parts directly from us online via the app.
Principle of operation
After the material sample has been picked up in a measuring cup, this is inserted into the measuring cell (sample chamber) via a handling device and the volume of the sample is determined there according to the selected presetting.
After the multiple determination of the volume, the handling device transports the material to the balance for the determination of the sample mass.
The two parameters volume and mass are now known, and the density of the sample is automatically calculated from these.
Finally, the handling device removes the measuring cup and empties the material sample into the emptying device. There, the measuring cup is additionally cleaned with compressed air and is then ready for the next sample.
Since the sample volume must be matched to the volume of the measuring cup for precise measurements, the fully automatic gas pycnometer offers the option of holding different measuring cups in parking positions in the device.
For automatic calibration, one of the measuring cup parking positions can be provided with a calibration volume so that recurring measurements for recalibration can be performed during operation.
When selecting the components, special care was taken to ensure that both the mechanical measurement setup and the selection of the measuring transducers, as well as the evaluation electronics, lead to reproducible measured values with a low standard deviation.
In addition, the inside of the insulated housing is heated or cooled via Peltier elements as required to keep the temperature for the measurement constant.
