DPM Needle Purge Configuration (A5)

The ability to purge the needle assembly ensures there is no residue or build up in the needle assembly after retrieval of a representative liquid sample. The unit offers the possibility to purge the bottle with an inert gas prior taking a sample. The DPM type sampler in needle purge configuration allows purging through the needle assembly at a recommended maximum operating pressure of 8 bar. This liquid sampler offers  one-handle operation, providing safety for the operator and zero emission.

Provide a new septum on your sample bottle. Insert the bottle, with cap and septum into the sleeve until the septum is pierced by the needles. Put the bottle retaining clip in place.

Turn the handle to the “sample” position, allowing the product to flow into the sample bottle. When the required amount has been taken, turn the handle to the “off” position.

Turn the handle to the “needle” position, allowing a flow of purge gas through the sampler to ensure any residual liquid is forced into the sample bottle. This position can be held for any required time.

Turn the handle to the “off” position. Remove the bottle retaining clip and pull the bottle out from the sleeve. The septum reseals automatically.
