S32 Back and Needle Purge Configuration (E2) On Dopak, Inc.

The ability to create an under pressure in the sample bottle by 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 & needle purge configuration allows a gas to purge the sampler and process connection prior to sampling ensuring a fresh sample and allows purging through the needle assembly.
All S32 type of samplers offer a one-handle operation by multiple valves.
