8 Sample Valve with Septum Port
The gas sample valve serves to draw gas samples from the head space of the ECC-
Press-Air test cell. In the closed state, the valve spindle is seated on the PTFE ferrule
and is thus preventing any bleeding from inside the cell through the septum. In order
to draw a gas sample, i) pierce the septum with the sample syringe, ii) open the valve
by turning the valve handle counter-clockwise by 90 degrees, iii) charge the syringe,
iv) close the valve by turning the valve handle clockwise till finger tight, and remove
the syringe.
