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.
