The EZ-mixVR variable ratio meter, mix and dispense system is a piston-based, software-driven, positive displacement system that offers accurate mixing without changing gears or other time-consuming mechanical adjustments. It features 0.1 ml repeatability, and users can achieve variable ratio dispensing in 1/100th increments from 1:1 to 20:1 through the keypad. It is designed to eliminate the process of waiting for piston pumps to refill with material from reservoirs. DTIC Dispensing Technologieshttp://rbi.ims.ca/4911-590
