The invention concerns a sampling device for extracting a sample from a sealed bulk product, for example, a solid product such as a block of cheese, or a granular product such as milk powder. The device comprising a sample extraction means, which may be a trier or tube (2, 30, 52) insertable through a seal (25, 66) into the bulk product (10, 60) for extraction of the sample (11, 61). The sample extraction means (2, 30, 52) is contained within a sealed air-tight envelope (4, 54) and has sealing means (5) for connecting the encapsulating means (4, 54) to the seal (25, 66) of the bulk product (10, 60). The sample is extracted into the envelope (4, 54), and the envelope is then heat-sealed such that the sealing means (5) reseals the bulk product after extraction of the sample (11, 61). The sample is thus removed in an aseptic manner without permitting contamination of the bulk product. The device for extracting the sample from the bulk product (10, 60) may comprise a trier (30) which has a hollow tubular body (32) and a pointed end (34). A wall (33) defining the tubular body (32) of the trier (30) has at least one, but preferably two, lines of weakness extending axially of the trier (30) by means of which the trier (30) may be broken open to release the sample.
