The Concorde Convertible Tip Hand Probe is designed to work with the Microlab 600. It is shipped standard with the Single Syringe Dispenser, Dual Syringe Diluter and the Continuous Dispenser. This probe is most commonly used with 12 or 18 gauge tubing but may be used with tubing as large as 1/8 inch for viscous liquids. A red/green LED incorporated into the hand probe alerts the user when the instrument is ready to trigger. For comfortable operation the probe tip can be oriented at either 0 or 15 degrees. Using the Luer Lock Conversion Kit the tip can also be converted into a Luer Lock termination that can be used with standard Luer Lock needles. e.
