6. Sample Container: provide 3ml, 10ml, 15ml and 70ml standard containers, also can customize any volume containers from 1-500ml.

7. Pressure Accuracy: imported high-precision pressure transducer, accuracy can reach 0.05% F.S., stability 0.025% F.S.

8. Adsorbate Gas: high purity Helium or air or Nitrogen

G-DenPyc 2900 gas pycnometer true density analyzer features

1. Data Reduction: high-precision PρT gas density calculation model eliminates measurement errors caused by non-ideality gas state, can increase analysis accuracy

2. Thermostatic System: analysis modules designed with thermostatic system can control temperature up and down easily, also hold modules stay at the best temperature(25 C) which can restrain transducer reading’s temperature drift and keep system temperature uniformity; System can maintain temperature at a fixed value for some fixed-temperature-required samples

3. Control System: programmable logic controller (PLC) system obtains high integration and strong anti-interference, software operated fully automated analysis enables freely choose of multi measurement modes

4. Analysis Management: programmable built-in system, touch screen, USB type external keyboard and mouse, operated by connecting to computer is available

5. Manifolds System: patented V-Sorb monolithic manifolds system can improve sealing performance and reduce dead space largely, enhance system temperature’s uniformity and anti-interference ability, all lead to a high accuracy and repeatability data

6. Splash-proof Measures: installed with a detachable filter in sample cell’s bottom, can prevent samples be suctioned into manifolds; inputting gas from bottom of cavity can avoid samples splash and software controlled H-Sorb two-stage-stepping mode further ends splash happening

7. Sample Container: Exclusive G-DenPyc filling technology supports to choose different volumetric aluminum blocks to fill cell instead change other sizes cells according to samples’ volume, this innovative method realizes minimal free space in cells and improve experiment accuracy
