ABSTRACT:
A motionless mixer tube for mounting on the end of a discharge nozzle of a dispensing device for mixing and dispensing extremely small volumes of a pair of liquid materials, such as chemical reacting resins. The mixer tube has an elongated housing with a female luer lock at one end for mounting the tube on the dispensing device, and a male luer lock on the other end for easily mounting a dispensing needle on the outlet end of the housing. A helical motionless mixer element is mounted in a bore of the tube housing and extends from immediately adjacent the outlet end of an inlet socket of the female luer lock to immediately adjacent the outlet end of a discharge nozzle of the male luer lock. The dispensing needle is mounted immediately adjacent the outlet end of the discharge nozzle and mixer element. This arrangement avoids dead spaces within the mixer tube to prevent the formation of disruptive air bubbles therein and enables secure and rapid attachments at both ends of the tube.
