A sample vessel (1) for taking very small amounts of blood, consisting of an outer vessel (2) and an inner vessel (3) which can be inserted into it, which is closed at the bottom, and on top, on the side where the sample is deposited, is configured with an open, very thin-walled blood sample ring (7) which can be closed by a stopper (4) and which protrudes in situ from the outer vessel (2). The outer vessel (2) has a collar (5) which supports the inner vessel (3) below the blood sample ring (7), and which is suitable for holding in centrifuges. The sample vessel makes taking blood samples easier, is simpler to produce and offers a greater variety of possibilities for use.
