Pentapyc™ 5200e Gas Pycnometer

BRAND :

Five station, automatic gas pycnometer for specific volume and true (skeletal) density measurement of porous solids and powders. Each of the five stations can be individually "tailored" for different sample amounts/shapes. Features data archiving to PC (Ethernet) or USB flash/thumb drive, interface to electronic balance and USB printer port. Easy-seal™ covers ensure reproducible operation. Thermostatted version available.

FEATURES :

Automatic Functions:

Operating simplicity is achieved by user prompts or instructions via keypad or PC (see below). Measurements and printout of results are totally automatic. Continuous self-diagnostics monitor and signal fault conditions that may arise. The transducer is reset to zero prior to each run. Front panel LED's display the operational status at all times.

Sample/User Identification:

In the analysis parameters, up to 16 alphanumeric characters may be added to uniquely identify both the sample and operator.

Temperature:

Sample temperature is displayed and printed to ±0.1°C. This feature is important for (a) verifying operation at the calibration point or, (b) making corrections when analyzing larger quantities of materials whose density varies significantly with temperature. Optional temperature controlled capability is available (requires an external bath/circulator which is sold separately).

Target Pressure:

The measurement of pressure-deformable cellular foams (insulation) is made possible by this feature. A user can conveniently reduce the target pressure typically from around 18 psig to as low as 0.5 psig. Special versions, the UltraFoam ™ & PentaFoam, automatically scan for the optimum pressure for subsequent measurement of open and closed cell content, with or without for correction for cut cells, per ASTM D6226.

Sample Purge:

Before analysis, samples are automatically conditioned to remove contaminants and trapped air. The user has a choice to purge by a continuous flow, or by a pulse mode for powders. The Pentapyc purges all five stations simultaneously thus requiring no more time than for a single analysis. Evacuation mode is also included in the Ultrapyc (requires vacuum pump, sold separately).

Repeat Run Mode:

This feature eliminates the need to reenter the same set of analysis parameters prior to each run. It allows one to quickly change sample weight and sample ID, or simply to rerun a sample.

Useful Statistics:

For three or more averaged measurements the % coefficient of variation and the standard deviation of the Volume and the Density are reported. This allows a relative comparison of samples from run-to-run and a precise assessment of the absolute variation of the sample being measured.

NIST Traceability:

Pycnometer volume calibration spheres can be provided with a report of calibration using measuring devices traceable to National Institute of Standards and Technology.

PC Connectivity:

Both Pycnometers feature Ethernet connections to a PC and communication via a standard web browser. Analysis can be started and monitored from the PC, even remotely on a network. Reports can be accessed for analysis on the PC, or can be stored on an external USB flash / thumb drive.
