Request Information
  • 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.
