ABSTRACT:
A device for sampling remotely either liquid or solid from the bottom of a tank or other container is provided. The device comprises an outer cylindrical body of a relatively dense material having a suspending handle and a central opening through which a piston assembly is positioned and including an enlarged portion of the central opening functioning as a liquid sampling chamber. A piston assembly provided at the upper end with a piston rod and at the lower end with an enlarged piston head is positioned within and from the bottom of the central body opening with the enlarged piston head engaging at its top the bottom of the sampling chamber. The piston assembly is held within the body by a cylindrical sleeve element which is threaded into the lower portion at the body and is adapted to core out a sample of solid deposits. The piston head contains an "O" ring which at the bottom of the piston stroke engages the lower portion of the inner tapered bore of the cylindrical sampling element thereby closing the liquid sampling chamber. The device is suspended at the top in either a liquid or solid sampling mode depending on the specimen desired and lowered by gravity into the container from which a sample is to obtained.
