摘要： Extracting a quantity of liquid from a closed container by driving a cannula having a passage the length of the cannula and a groove a partial length of the cannula through the closure of the container until the groove establishes communication between a pressurized chamber and the container, thereby forcing liquid from the tube through the passage.

摘要： A method for measuring or controlling the volume of a liquid segment confined within a tube and having a leading edge and a trailing edge. The tube is exposed to radiation at an angle and radiation refracted from the inner surface of the tube is measured at the leading and trailing edges of the segment while the liquid segment is moving through the tube.

摘要： Assays for separating magnetic particles include separating magnetically responsive particles from a liquid dispersion disposed in a plurality of reaction vessels, and transporting the reaction vessels in sequence past at least one processing position. A robotics reagent arm and probe dispense reagents into the reaction vessels and a reaction monitoring device is capable of relative movement with respect to the transporting device. Incomplete separation is effected by positioning a magnetic field in contact with the reaction vessel for a first shortened time interval during which the particles partially aggregate and afterwards are removed from the reaction vessel. The magnet is repositioned in contact with the reaction vessel for a third time interval to achieve full separation of particles from the liquid.
