ABSTRACT:
A fluid sampling device has an elongate tube formed substantially of polyphenylene sulfide. A top end fitting is formed to the top end of the tube and is configured for connection to a tether. A bottom end fitting is similarly formed to the bottom end of the tube and has a check valve formed therein for allowing fluid to flow therethrough into the tube when the fluid sampling device is lowered into a fluid and for inhibiting fluid flow therethrough out of the tube when the tube is being raised and handled. The tube, top end fitting, bottom end fitting, and check valve are all formed of an inert material so as to maintain the integrity of the fluid sample collected. The use of polyphenylene sulfide provides a lightweight fluid sampling device which is durable enough to resist damage during routine handling and use.
