Abstract
A displaceable needle (16) for sampling the liquid from the flask is mounted on a slide (5) that is mobile vertically in relation to a support bracket (1) integrated in the sampling apparatus. The sampling needle passes through a percussion head (10) mounted on the base of the bracket and to which is connected a piercing needle. A conduit (12) for rinsing places the percussion head in communication with the outside. Application to blood sampling in a haematological analysis apparatus.
