AF Deep Sampling System

(Patent N01247605)

AF DEEP SAMPLING SYSTEM has been projected and engineered to solve a specific problem quite common in water sampling for environmental and geochemical purposes: sample original volatile content preservation avoiding exsolution and consequent solute precipitation.


The applied technology allows easy deep sampling operations both in open water or boreholes using the same equipment.



  • accurate sampling depth determination;

  • avoiding contamination of the sampling chamber by fluids present at depth different from the aimed one;

  • maintenance of sample's original baric condition;

  • easy operation even in confined spaces or from small boats.


all hydro-geochemical and environmental deep water sampling operations where accurate determinations of sample original composition and quantitative volatile content is at price




  • PRESSURE SOURCE: nitrogen cylinder and pressure regulator;




TECHNOLOGY: remote pneumatic control.



  • Sampling chamber baric conditions continuously and positively controlled from surface;

  • Real time check of effective filling of the sampler;

  • Hydrostatic pressure loaded spring avoiding gas or volatile sample exolution maintaining the sample original depth pressurization;

  • Sampling chamber, interchangeable, works also as sample store and allows positively controlled gas exolutions conditions and sample spilling with very low baric gradients directly to HPLC analyzers etc...;

  • Minimum dead volume special plug type valve design avoid trapping of fluids overlying the required sampling depth;

  • Gas operating the pneumatic bailing is positively prevented to came in contact with sample;

  • OPERATING DEPTH: from 0 to -400m below WRL;

  • OPERATING TEMPERATURE: from freezing point of the fluid to be sampled to +60C;

  • SAMPLING CHAMBER VOLUME: from 0 to 1000cc;

  • CHEMICAL SAMPLE COMPATIBILITY: sampling chamber built in or lined by INOX AISI 316, PPHD, PTFE;

  • TOTAL WEIGHT: 18 Kg;

  • FEXT SAMPLER: 5 cm (2");

  • CREW: N 1 operator;
