A bulk sampling device for sampling mixtures of powder and semi-solid compositions. The sampling device comprises an apertured hollow outer tubular casing for receiving an inner receiving rod with adjacent non-communicating sample ports for holding sampled materials. The inner rod also contains removable partitions located between each sample port thereby forming non-communicating sample ports and diminishing the risk of leakage and contamination between each port. The removable partitions, located between the sample ports, are dimensioned and positioned within the partition receiving slots such that each partition remains trapped between the outer hollow tubular casing and the receiving rod when the device is assembled. The distal end of the device has a solid cone, and the proximate end has a handle to manipulate and rotate the inner receiving rod and sample ports to obtain volumetric sampling.

1. A bulk sampling device for taking multiple volumetric samples from the same area and at different depths of powder or semi-solid mixtures, comprising:a hollow outer tubular casing; an inner bulk sampling receiving rod; said hollow outer casing having a predetermined length, an interior wall dimensioned to smoothly receive said inner receiving rod, at least one aperture, a distal end and an opened proximate end for receiving said inner receiving rod; the proximate end of said hollow outer casing having a grooved guide pin receiving pattern; the distal end of said hollow outer casing having first engaging means; said inner receiving rod having a predetermined length for fitting snugly and removably inside said outer tubular casing, a proximate end, a distal end, an inner wall, an outer wall, at least one bulk sample receiving port, at least one removable partition and at least one partition receiving slot; the proximate end of said inner receiving rod has a handle and a guide pin; wherein the bulk sample port being aligned with and having greater dimensions than the aperture in said tubular casing such that the partition receiving slot is positioned adjacent the bulk sample port and the removable partition is positioned within the receiving slot such that each of the bulk sample ports are non-communicating with each other and the partition remains trapped within the receiving slot when said inner receiving rod is completely inserted into said hollow outer casing; and a solid cone having a proximate end, a distal end, and second engaging means located at said proximate end which engages said first engaging means and closes the distal end of said outer tubular casing; wherein manipulation of the handle of said receiving rod enables movement and rotation of said receiving rod thereby guiding the guide pin along the grooved guide pin receiving pattern of said outer hollow tubular casing such that when the bulk sample port is offset from the aperture in said outer tubular casing the bulk sample port is in a closed position.
