On delivery, the critical point apparatus is filled with
hydraulic fluid. The test gas is not included.
Before filling with the test gas, carry out a volume
calibration, as described in chapter 6, using air as an
approximation of an ideal gas.
Filling with the test gas is described in chapter 7.
Experimental investigations are described in chap-
ter 8.
Important notes on storage of the test gas and
equipment (if not in use for a long period) are stated
in chapter 9.

Owing to the inevitable diffusion of the test gas
through the conical seal, it is necessary to degas the
hydraulic fluid in the equipment, as described in
chapter 10. This must be done before the equipment
is put away for storage (after removing the test gas) or
if it has been in use for a long time.
The threaded bush in the frame must be lubricated
regularly and also inspected at lengthier intervals.
Refer to section 11 for instructions.
Maintenance work as described in chapter 12 is only
required if the rubber components get worn out and
their functionality is adversely affected.
