Apparatus for taking samples of biological liquid and in particular human blood comprises an elongate body having a longitudinally extending central passageway connected at one end to a hypodermic needle. Branch channels extend respectively from the central passageway to individual test tubes which are supported by their upper ends along the lower side of the body. The test tubes are sealed so as to remain in sterile condition and means is provided for selectively venting air from the test tubes and controlling flow of liquid from the central passageway to the individual test tubes so that they can be filled successively or as desired. The test tubes are removable from the body for carrying out the several tests or analyses for which the samples are intended. |
