A fluid collection, dispensing and measurement device for use in connection with a blood container, for example, and flexible tubing leading thereto. A hollow balance bar, with mobile spherical weights disposed therein is provided and rapid, forceful cut off of the blood flow through the flexible tubing is achieved when the moment created by the filling blood container, accentuated by the motion of the spherical weights, overcomes the moment produced by a preset adjustable counter weight. An adjustable clamping apparatus allows the fluid collection device to be affixed to a stationary object and subsequently adjusted to a level plane to insure accuracy of measurement. A simple modification of the device allows it to be used as a fluid dispensing device. A full container of fluid can be hung on the modified device and a measured quantity of fluid can be dispensed with cut off being achieved as described above.
