ABSTRACT:
A soil sampling device for collecting samples of soil provides a single use unit with an integrally molded plunger. The soil sampling device includes a cylindrical body having a first chamber and a second chamber, with each chamber comprising a cylindrical wall having a longitudinal axis and an end wall. Optionally, the sampling device may include additional chambers depending on the application. An open end of each chamber defines a mouth which is adapted for inserting into soil. A piston may be positioned within each chamber, and the end walls include a projecting member extending outwardly therefrom which defines a plunger. The end wall includes a reduced cross-section around the projecting member and is adapted to break when a force is applied to the projecting member to thereby permit the plunger enter into the body and thereby push the piston along the longitudinal axis to expel a sample of soil collected in the body. Preferably, the piston is frictionally held in the body, for example by frictionally engaging an inner surface of the cylindrical wall. Optionally, the piston includes at least one seal for frictionally engaging the inner surface of the cylindrical wall.
