A Soxhlet extractor is a good tool when you want to extract the desired compound from the solid material, especially when you find that the desired compound has relatively low solubility in a solvent, or the impurity can be insoluble in that solvent completely. And the extraction thimble is a small test-tube shaped item, holding the material which is subjected to solvent extractors.
