The present invention provides fluid sampling device comprising a sampling head having a series of openings through it from one major surface to the other, a plurality of conduits at the downstream side of the openings and a plurality of sample containers. The openings are selectively opened and closed through the use of switches mounted within each opening and the head of the device members, each switch being movable within said head between closed and open positions. The conduits (e.g., flexible tubing) are equal in number to the openings, with each conduit connected to an individual port fitting arranged on a face of the head downstream of the respective opening. Similarly, the sample containers (e.g., flexible bags) are equal in number to the conduits, with each sample container connected to an individual conduit opposite the connection to the port. A specific configuration for the device, as well as a kit containing pre-sterilized components of the fluid sampling device, are also described.
