True density analysis of powders and bulk solids
Gas pycnometers measure the true density of solid samples using an inert gas to measure the sample volume by applying Archimedes’ principle of displacement. Unlike similar devices that use liquids (water, alcohol, or kerosene), these instruments are easy to use and do not affect the surface chemistry or physical structure of the sample during measurement. PentaPyc 5200e measures up to five samples sized from 1 cm³ to 135 cm³ with the highest level of accuracy due to its multiple built-in expansion volume chambers.
Access to Results
Detailed reports may be printed, emailed, or saved to a USB flash drive immediately following an analysis. Results are retained internally in text and pdf format for access via PC for remote printing, sharing, and archiving.
Direct Input of Sample Mass
An RS232 port for connection to an electronic balance to obtain the mass directly is included. Mass may also be entered at the keypad or via the PC interface
Direct operation
Analyses can be setup and started using the built-in keypad or PC via ethernet. Menu selections and
prompts are presented on a backlit display located on the front of the unit.
Automatic Sample Preparation
The sample chamber is automatically purged with analysis gas per operator protocol. Vacuum assisted
sample preparation is also available on the UltraPyc 1200e.
Customizable Analysis Parameters
Define sample preparation protocol, number of expansions, repeatability acceptance criteria, equilibrium conditions, and target pressure.
Automatic Repeated Analysis
Measurements are automatically repeated until a specified number of contiguous measured values agree within a specified deviation. Data averaging and statistical calculations are performed automatically.
NIST Pedigree
Calibration spheres can be purchased with a formal Report of Calibration provided by the National Institute of Standards and Technology: Not simply traceable to NIST, but actually measured by NIST.
Easy to Use
Samples are easy to load and unload. Measurement protocols are easily invoked either at the unit or via a web browser with pre-installed software.
Fast Initialization
A new analysis requires only that correct sample ID and mass be entered. The entire analysis protocol
remains in memory for the next analysis.
Time Saving Operation
Automatic analysis completely frees the operator for other tasks while the unit works totally unattended.
The PentaPyc 5200e can analyze up to five samples.
Emphasis on Precision and Accuracy
The sample chamber is vented and the pressure transducer is zeroed before every expansion, not just
when a fresh sample is initialized. The appropriate expansion chamber is automatically employed.
Focus on Reproducibility
The pycnometers retain volume calibrations in memory even when powered down – regular adjustment is not required. The system temperature is displayed in reports for verification of suitable and stable measurement conditions.
Adaptability
Optimal performance is assured by multiple sample cup sizes and multiple expansion chambers for the micro-processor, not the operator, to choose from.
Pre-Calibrated, Re-Calibrate Any Time
All pycnometers are factory calibrated and ready to use right out of the box. Re-calibration is easy to do
with the supplied set of reference volume spheres.
Automatic Troubleshooting Alerts
Loss of gas pressure, unstable pressure, and other fault conditions are automatically reported to the operator for remedial troubleshooting action.
The UltraPyc 1200e Automatic Gas Pycnometer is used for the measurement of true density and volume of solids. The UltraPyc 1200e features automatic “repeat run” measurement mode until the results fall within a user-specified tolerance or achieve a user-specified maximum number of runs.
The appropriate expansion (reference) volume is automatically chosen by a microprocessor according to the sample cell selected. Reports include density and volume results with statistics. In addition, the instrument features a USB printer port, a second USB port for a flash/thumb drive, ethernet port for PC (automatic operation via web browser) or network, RS232 balance interface, and a storage compartment. Supplied complete with three interchangeable sample cells (10, 50 & 135 cc) and a full set of calibration spheres.
