  • Being able to provide a jet purge adapter to a piston (RAM) type sampling valve, ensures optimal retrieval of a representative sample of high viscosity liquids.
  • The DPJ type sampler in solvent purge configuration allows purging of the sample valve outlet thus eliminating dead volume.
  • The solvent purge allows purging with a suitable solvent or with nitrogen.
  • Recommended maximum operating pressure is 8 bar.
  • This liquid sampler is operator friendly and provides zero emission.
