摘要： A sampler apparatus for unit dose bulk material sampling comprising an elongated housing having a first bore extending therethrough and a moveable piston rod extending through the first bore forming a sampling cavity between the front surface of the piston rod and the front end of the housing. A closure cap is attached to the front end of the housing and is adapted to selectively open and close the entrance to the sampling cavity. Also included are adjusting means for adjusting the size of the sampling cavity and compacting means for compacting the sample while the sample is contained within the sampling cavity.

摘要： A bulk material sampler comprising an elongated body having a first axial bore and an interior wall, a handle having a second axial bore and a finger grip, and a shaft assembly axially supported. inside the first and second bores. The bottom end of the handle is connected to the top end of the body. The shaft assembly comprises a tip at the shaft assembly bottom end and a button at the shaft assembly top end. The button is adapted to protrude from the handle top end. The shaft assembly is axially moveable between an actuated position in which the button is maximally depressed within the handle, and a resting position in which the button maximally protrudes from the handle. The sampler further comprises means for biasing the shaft in the resting position, and a sample collection cavity defined by a portion of the tip and a portion of the body interior wall. The tip may be removable from the shaft assembly. A plurality of tips having different configurations tailored for sampling different bulk materials are claimed, as are methods for taking a sample using the sampler.
