Micromeritics AccuPyc 1330 Pycnometer
For very precise density measurements of small samples.
The MicroMeritics AccuPyc 1330 Pycnometer is a fast, non destructive, fully
automatic density analyzer that provides high-speed, high-precision volume
and density measurements on a wide variety of materials.
This pycnometer is a device that determines the density of small samples
by actually measuring their volume very precisely. The sample mass is
measured on a high quality balance and entered into the pycnometer software
to give the sample density. The volume is measured using the Gas Displacement
Technique. MicroMeritics describes it this way:
|
The AccuPyc works by measuring the amount of displaced gas [helium].
The pressures observed upon filling the sample chamber and then discharging
it into a second empty chamber allow computation of the sample solid phase
volume. Gas molecules rapidly fill the tiniest pores of the sample; only
the truly solid phase of the sample displaces the gas.
