Abstract: A sampler for acquiring a sample of blended powder from diverse locations within a bin is described. The sampler has a cylinder with a hollow chamber formed therein and is connected to a handle for rotation within a housing tube. Rotation causes the chamber to move into or out of alignment with an aperture in the housing tube. When the sampler is inserted axially into a batch of blended powder, the cylinder is rotated to align the chamber with the aperture in the housing cap, allowing powder to enter the chamber. The cylinder is rotated back to close the chamber, and the sampler is withdrawn from the powder batch. The cap is removed from the housing and the cylinder is removed from the housing to transfer the sample of powder for analysis.

Abstract: 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.
