• 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 purge configuration allows purging of the sample valve outlet thus eliminating dead volume.
• The jet purge adapter has two flow paths.
• The first flow path allows the product to flow to the sample bottle and the second flow path enables the jet purge adapter to be purged with an inert gas.
• Recommended maximum operating pressure is 8 bar.
• This liquid sampler is operator friendly and provides zero emission.

• The ability 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 fixed volume configuration allows purging of the sample outlet of the valve to eliminate dead volume in addition to a fixed sample volume.
• The jet purge adapter has two flow paths.
• The first flow path allows the product to flow into the sample bottle and the second flow path enables the jet purge adapter to be purged with an inert gas.
• This liquid sampler is operator friendly and provides zero emission.

• The ability 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 fixed volume with cooling/ heating jacket configuration allows purging of the sample outlet of the valve to eliminate dead volume in addition to a fixed sample volume at the required temperature.
• A separate cooler/heater is not necessary.
• The jet purge adapter has two flow paths.
• The first flow path allows the product to flow into the sample bottle and the second flow path enables the jet purge adapter to be purged with an inert gas.
• This liquid sampler is operator friendly and provides zero emission.

• 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.
