In a device for taking samples from a material flow of fine-grained and dry material, in particular in the cement industry, comprising an upwardly open sample chamber (2) capable of being introduced into, and retracted from, the material flow through an introduction socket, the sample chamber (2) is formed in a rod-shaped body (1) translationally guided between a sampling position and a retracted position, and the sample chamber (2) has an openable bottom (7).
