Abstract
Systems and methods for dispensing radioactive liquids using a liquid dispensing apparatus are described. The apparatus includes a support arm rotatable about a rotation axis, an actuator operatively connected to the support arm and configured to at least one of rotate the support arm about the rotation axis and displace the support arm in a direction parallel to the rotation axis, and a pipette assembly mounted to the support arm. The pipette assembly includes a pipette tip defining an opening through which liquids are aspirated and dispensed, a piston, and a stepper motor operatively connected to the piston to control linear displacement of the piston.
