DOPAK® Process Sampler Type S32
back purge configuration with vacuum connection (E1)

The ability to create an under pressure in the sample bottle by a
connection to a vacuum source ensures optimal retrieval of a
representative, contamination free sample from processes at
vacuum conditions or atmospheric pressure.
The S32 type of sampler in back purge configuration allows a
gas to purge the sampler and process connection prior to
sampling ensuring a fresh sample. All S32 type of samplers offer
a one handle operation by multiple valves.

1 OPERATION/FUNCTION
0 - off
Provide a new septum on your
sample bottle. Insert the bottle,
with cap and septum into the
bottom part of the bayonet
sleeve.
Connect the bottom part of the
bayonet sleeve to the upperpart,
move the bottom part upwards
and lock it by turning it in the
slot in the top end position.

1 - back purge
Turn the handle to the “back
purge” position, allowing a flow
of purge gas through the sampler
to the process to ensure representative sampling. This position can
be held for any required time.

2 - sample
Turn the handle to the “sample”
position, allowing the vacuum to
be connected to the vent outlet
of the needle assembly to create
an under pressure in the sample
bottle. The product flows into the
sample bottle.
When the required amount has
been taken, turn the handle into
the “off” position.

3 - off
Move the bottom part of the
bayonet sleeve slightly upwards,
turn it and pull it out from the
upper part. The septum reseals
automatically. Take the bottle
out from the bottom part of the
bayonet sleeve.
