ABSTRACT:
A self-sealing fluid collection tube is provided with an elongated bore and a fluid entry end. A plug of super-absorbent material is provided within the tube opposite the fluid entry end. This plug is preferably vented and is adapted to seal the tube by expanding when contacted by a fluid, such as blood. After the fluid has been collected, the tube is placed in a pipetter-dispenser in which a plunger, which is inserted into the tube, moves through a calibrated distance thereby advancing the plug into the tube and expelling a selected volume of fluid from the tube. Alternatively, the fluid may be transferred into another receptacle by piercing the sealed plug to form a new vent channel to permit drainage of the collected fluid into a receptacle.
