Apply nowThe Micromeritics AccuPyc gas pycnometer is globally trusted to provide the most reliable determinations of true density. Preferred by more labs than any other commercial gas pycnometer, the AccuPyc delivers the highest available accuracy and repeatability in a fast and easy system for any operator to use.
Download brochureStreamline your workflow and avoid transcription errors by connecting the AccuPyc to your lab balance via USB. Sample mass is directly transmitted, reducing manual steps and the potential for user error.
The Micromeritics AccuPyc can also integrate with other lab input devices like a keyboard or barcode reader to streamline user interaction.
The intuitive Breeze touch interface gives you everything you need at your fingertips.
Perform a measurement, review past results, send a report to print or to LIMS with the touch of a finger. Save space in your lab by eliminating a PC from the bench.
Never lose past results or worry about outdated method settings. MIC NET is an instrument-to-instrument network that shares and stores results and methods across devices, including forward compatibility with your existing Micromeritics AccuPyc.
Different materials require different operating conditions — whether you're testing light powders, granules, foams, or slurries. Define optimal conditions for your processes and save them in the Method Library. Easily recall them whenever needed, so you always measure the same way — the right way.
The density of battery cathode and anode materials is directly related to their porosity, which affects the amount of energy that can be stored per unit volume. Density is also an effective indicator of the purity and composition of the electrode materials, which is crucial for increasing battery capacity.
Monitor and control composition of API’s and excipients by measurement of product density. Differences in polymorphic, hydrated, and amorphous forms of products, as well as purity, can be detected through density measurements.
Track the purity of raw materials through density measurement. Detect the presence of occluded porosity developed during sintering processes that impact final product strength.
Determine total solids content of liquid coatings to predict coverage. Monitor density of dry pigments and powder coatings to verify composition. Detect density differences in cast films that indicate changes in crystallinity and mechanical performance.
Determine total pore volume and porosity of core samples to quantify total storage capacity. Quickly assess the composition of the solids used in drilling fluids.
Determine correct composition of catalyst supports and finished products including crystallinity, porosity, and formulation.
Determine the ratio of open and closed cell foams, which impacts heat transfer, gas transport, sound damping, mechanical energy dissipation, and buoyancy. Differentiate relative amounts of crystalline and amorphous phases of thermoplastic polymers. Design and produce composite materials with precise control of fiber loading, void content, mixing uniformity, and fiber impregnation.

The Micromeritics AccuPyc supports a wide range of measurement volume — without sacrificing accuracy or adding complexity — with simple volume insert kits.
The Micromeritics AccuPyc is a more stable system that equilibrates faster and exchanges gas more efficiently, which leads to shorter run times.
Complete your measurements in 20-30% less time than any other pycnometer.
The design of the AccuPyc reduces variability and enhances accuracy: the most stable temperature control, cutting-edge gas modeling, the most repeatable lid closure, and more.
Superior measurements for accurate results you can trust.
A hinged, self-aligning lid makes operation simple and error-free for any user.
Swing. Turn. Done.
Combined with an intuitive control and display panel, the AccuPyc is the easiest instrument you will ever add to your lab.
Precision control from 4 °C to 60 °C empowers you to measure density at conditions that match your process.
AccuTemp features a quiet, air-cooled thermoelectric temperature control system.
Every Micromeritics AccuPyc includes AccuTemp, which guarantees temperature stability to ±0.025 °C or better.
The most stable temperature ensures the most reliable, repeatable density measurement every time.
Measure solid density with no additional steps, calibrations, or compromise, utilizing nitrogen, air, argon, and more.
Advanced technology proven in Micromeritics’ industry-leading gas adsorption instruments allows you to switch gases and save helium when testing non-microporous and non-adsorbing materials.
PowderSafe mode keeps your sample and instrument safe when testing light, fluffy powders.
The reference chamber is pressurized before the sample chamber, eliminating potential elutriation during fine powder measurements. Select it in your stored method and never worry again.
