DOPAK® Process Sampler Type S32-LG
system purge configuration (F1)
The ability to purge the sample point ensures optimal retrieval of
a representative, contamination free sample. The S32-LG type
samplers provide a system purge in addition to sampling in a
sample cylinder with a predefined filling rate. The predefined
filling rate is achieved by using an expansion chamber.
The unique design offers a one handle operation by multiple
valves. These features provide sample accuracy and safety.
This sampler type is suitable for liquefied gases and liquids.

1 OPERATION/FUNCTION

Install the sample cylinder and
connect the flexible hose to
the bottom side of the sample
cylinder. Open the needle valves
of the sample cylinder.

Turn the handle to the “process”
position, allowing the sample
cylinder to be filled. To ensure
representative sampling, this
position can be held for any
required time.

2 - expansion
Turn the handle to the “expansion”
position. The internal connection
between the sample cylinder and
the expansion chamber has now
been made. Maintain this position
for any required time to enable the

cylinder and expansion chamber.
Close the two needle valves of the
sample cylinder.

3 - vent
Open the valve on the expansion
chamber. The expansion chamber
and connections are being
depressurised to the vent system.
