The Fastest, Easiest, Most Accurate Measurement Of True Density
Gas Displacement Pycnometry
Gas pycnometry is used to determine the true — or skeletal — density of solid materials and slurries. A sample is placed in a chamber of known volume, which is sealed and pressurized. The gas fills the empty spaces within and between the sample particles. The sample chamber is then expanded to an adjoining reference chamber of known volume. The change in pressure is used to calculate the volume of the sample. True density is calculated from the sample mass and the volume it occupies. This method is useful for determining the true density of materials, even those with small pores and irregular shapes
The AccuPyc gas pycnometer from Micromeritics is trusted around the world to provide the most reliable measurements of true density. More labs choose an AccuPyc than any other commercial gas pycnometer. The AccuPyc delivers the highest available accuracy and repeatability in a system that is fast and easy for any operator to use. Measure solid density with nitrogen, air, argon, and more with no additional steps, calibrations, or compromise. Advanced technology proven in Micromeritics’ industry-leading gas adsorption instruments enables you to switch gases and save helium when testing non-microporous and non-adsorbing materials.
Powder Safe Is Worry-free
PowderSafe mode keeps your sample and instrument safe when testing light, fluffy powders. Pressurizing the reference chamber before the sample chamber eliminates the potential for elutriation when measuring fine powders. Select it in your stored method and never worry again
Not Just Fast, The Fastest
A more stable system that equilibrates faster and exchanges gas more efficiently leads to shorter run times. Complete measurements in 20% to 30% less time than any other pycnometer
Not Just Accurate, The Most Accurate
Every element of the AccuPyc design enhances accuracy and reduces variability: the most stable temperature control, cutting-edge gas modelling, the most repeatable lid closure, and more. Superior measurements for accurate results you can trust.
The Easiest Operation Ever
A hinged, self-aligning lid makes operation easy and error-free for every user. Swing. Turn. Done. Combined with an intuitive control and display, the AccuPyc is the easiest instrument you will ever add to your lab.
The Widest Range of Measurement Temperatures
Precision control from 4 °C to 60 °C empowers you to measure density at conditions that match your process. AccuTemp is a quiet, air-cooled thermoelectric temperature control system.
The Same Results Anytime, Any Place with AccuTemp.
Every AccuPyc includes AccuTemp that guarantees temperature stability to ±0.025 °C or better. The most stable temperature ensures the most repeatable, reliable density measurement every time.
Unparalleled Measurement Gas Flexibility
Measure solid density with nitrogen, air, argon, and more with no additional steps, calibrations, or compromise. Advanced technology proven in Micromeritics’ industry-leading gas adsorption instruments enables you to switch gases and save helium when testing non-microporous and non-adsorbing materials.
