Apparatus for use in blood and like sampling comprises a container and a fitting closure. The blood can be transferred to and from the container without removal of the closure. The container has a shelf to provide a sealing surface for the bottom of the closure which is received in an upper portion of the container. The closure is provided with passageways and is removable from a closed position in which the passageways are sealed against the shelf and a position which allows passage of blood to and from the lower portion of the container. The upper portion of the container can be of larger diameter than the lower portion and can be either concentric or eccentrically located with respect to the lower portion. An adaptor for use with the apparatus is also disclosed which allows a blood sample to be aspirated directly from a vein into the container through closure.
