A sampling device for use with an open necked container capable of holding a fluid material, comprises a hollow support member insertable into the container through the open necked portion thereof. The support member comprises a main body portion of a smaller diameter than the open neck of the container; a first end portion extends from the main body portion and is open to the ambient atmosphere through the open neck portion of the container. In one embodiment, elongated ribbed members extend from the main body portion and define a second end portion. The ribbed members form a generally rigid support structure. A dialysis tubing is fitted over the ribbed members and is closed at one end to define an open ended dialysis sac, the inside of which is directly accessible through the first end portion of the support structure. |
