: In a tool (called a sampling thief) used for sampling chemical powder compositions, it is known to have a tubular cylinder with one open end and one closed end, into which a sampler cavity is inserted. The tubular cylinder having slot in one end enables powder to fall into the sampler cavity which is inserted into the tubular cylinder. The sampler cavity which is adjustable allows for precise sampling sizes of chemical powders.
