The BetterPyc 380 Gas Pycnometer offers four measurements, including volume, density, solid content, and open cell content, all while preserving sample integrity. The device guarantees exceptional accuracy and dependability through temperature control, high-resolution transducers, and calibrated chamber volumes. The BetterPyc 380 Gas Pycnometer features automatic measurement, calibration, and leak detection, making it user-friendly for operators of all skill levels. The device also includes an integrated software solution that allows for direct balance connection and remote control of the external water bath. The BetterPyc 380 Gas Pycnometer requires only a small sample size of 1-100 cm3 and ensures the integrity of your samples is maintained.

The automatic gas pycnometer is based on the gas displacement method. It operates by introducing an analysis gas, such as helium or nitrogen, into a sealed sample chamber of known volume and then expanding it into a precise reference chamber. The volume can be accurately measured by recording the pressures before and after expansion.

The gas pre-heating is achieved through a precise temperature-control system that maintains a consistent temperature within a narrow range, resulting in more accurate measurements. The temperature-control system is an essential component of the automatic gas pycnometer design.

The gas is introduced into the sample chamber, displacing the empty space and penetrating the pores of the sample. The chamber lid, which provides a tight seal, ensures that the sample chamber is completely sealed and prevents any gas leakage during the measurement process.

Pressure 1 is recorded after the first equilibrium. The temperature control system maintains a stable gas temperature, allowing pressure to equilibrate to lower 0.005 psig/min. A high-resolution transducer measures the pressure inside the sample chamber after equilibration.

The gas is then allowed to expand into a reference chamber. Dual built-in reference chambers match the free space in the sample chamber for accurate results. The appropriate chamber is selected automatically based on the sample cup size, making it an ideal choice for precise density measurements.

Pressure 2 is recorded after the second equilibrium and the gas is vented into the atmosphere. After that, the result is calculated. An integrated vacuum pump extracts gas to improve purge efficiency and reduce measurement errors.

The BetterPyc 380 Gas Pycnometer, which complies with many ASTM and ISO standards, is a versatile instrument that can be used in a wide range of industries. The BetterPyc 380 Gas Pycnometer is capable of accurately measuring the density of a wide range of materials, the solid content in slurries, and the open cell content in plastic foams, enabling process optimization and quality assurance in relevant industries.
