Five-station gas pycnometers for true density:
PentaPyc and PentaFoam
- True density analysis of powders, bulk solids, and foams
- Built-in test methods and calculations of ASTM D6226 to describe open-cell content of foams
- Measure up to 5 samples simultaneously
PentaPyc 5200e and PentaFoam 5200e measure the true and skeletal density of solids and powders to track their purity and porosity via gas displacement. PentaFoam 5200e is also equipped with the test methods for measuring the open-cell content of foam according to ASTM 6226. Set up in just a couple of minutes and start as many as five density measurements in a single session – particularly convenient if your lab handles a variety of measurement types. The devices occupy about as much bench space as a laptop.
TruPyc technology for unmatched accuracy in all sample cells
PentaPyc 5200e and PentaFoam 5200e deliver accurate results whether you have only enough sample to fill the smallest sample cell or enough for the largest sample cell. This is of special importance as pycnometry relies on proper matching of the void space within the sample chamber to the volume of the reference chamber in order to avoid uncertainties. Each device has multiple reference chambers and automatically selects and uses the appropriate reference chamber based on the selected cell size.
Load up to 5 samples and walk away
PentaPyc 5200e and PentaFoam 5200e are ideal for high sample throughput in environments where space and operator time may be limited. Once the samples are loaded and the test methods have been entered, all you need to do is press ‘start’ – and PentaPyc/PentaFoam takes over. Purging of the cells can be performed on all five samples simultaneously or individually. After this step, the true or skeletal density is measured by gas pycnometry for each sample in turn. When the last sample is completed, a new batch can be loaded and started.
Five gas pycnometer stations in about the same bench space as a laptop
Just two single-station gas pycnometers take up more bench space than a single PentaPyc 5200e or PentaFoam 5200e. If you have limited space in your laboratory, these instruments give you all the measurement capacity you need, on a very small footprint.
Direct connection to weighing balances to prevent transcription errors
Eliminate the risk of possible transcription errors from manually entering sample weight data from an external balance by directly connecting your PentaPyc or PentaFoam to a balance using an RS232 communication protocol.
