摘要

Device for receiving liquids and for the exact removal of individual phases of the absorbed liquid, characterized in that it comprises a cylinder (1) in which a piston (3) along the longitudinal axis (2) of the cylinder (1) reversibly back and can be moved, wherein the piston bottom (11, 65) - in the plan view - in its central region a hole-shaped recess (4) which - by the piston (3) through - with a along the longitudinal axis (2) of Cylinder (1) aligned, rod-side extending and fully or partially transparent tube (5) is directly or indirectly in sealed connection or indirectly or directly into tight connection can be brought, wherein the inner diameter (13) of the lumen (52) of the tube (5 ) is in the range of 0.5 mm to 10.0 mm, the length of the tube (5) and its lumen (52) is in the range of 5.0 cm to 15.0 cm, and wherein on the - in vertical Orientation de s cylinder (1) - in the vertical direction upwardly projecting free end (14) of the tube (5) a reversibly closable cap (6) is provided or instead of this cap (6) a screw plug or a closure lid (53) are reversibly attachable in which a screw-thread-shaped and / or conical connection device (7) for an injection syringe (8) is provided in the closure cap (6) and wherein the overhang (54) of the closure cap (6) extending horizontally outward beyond the outside of the tube (5) is provided ), the screw plug or closure cap (53) - for finger rest during the aspiratory lifting of the piston (3) - and is in the range of 5.0 mm to 40.0 mm and wherein in the region of the center of the bottom (9 ) of the cylinder (1) on the outside a screw thread-shaped and / or cone-shaped connection device (10) for a cannula or for a screw-on or attachable stand (12) are provided and wherein in the bottom (9) opposite, the upper portion of the free end of the cylinder (1) on the outside circumferentially or oppositely provided projections (15) for finger rest.
