Abstract: A sampling and filtering device having a circular chamber 14 and a wing 20 for rotating the fluid in the chamber, an inlet in the centre of the chamber, and a first outlet to waste at the periphery of the chamber, a woven filter 24, securely fastened between the rims of a filter housing and a removable wall and supported by a grooved collector plate forming the removable wall 40 in the filter housing 14. The inlet and outlet are controlled by valves (16, 18), so that the filter chamber 14, the wing 20, the open inlet, and open outlet may function as a centrifugal pump. The filter 24 is cleaned by the rotating wing 20. The device enables a fast extraction of a series of samples from grape juices provided from different batches or truck-loads of grapes during the grape harvest.
