The Pro is our flagship dosing pen, machined from aluminum so it feels solid in the hand and stays put on the bench. A click-stop dial walks you to any setting up to 60 units, one audible click at a time. (You can dial it without looking.) It draws from a standard 3 ml borosilicate glass cartridge, the same one every AminoPen uses.
When you’re done, it snaps into its hardshell case. Bench, drawer, or bag, it travels protected.
