The Ratio:Matic® Series of Dual Head Dispensers & Metering Pumps provide precise dual channel fluid control for a broad range of process, production, laboratory, and OEM. 
Features:
Ratio:Matic® pumps consist of two FMI pump heads direct coupled to a single variable speed drive. Each pump head is independently adjustable, and a variety of pump head sizes can be used in combinations to achieve dispensing ratios from 1:1 up to 1000:1. Ratio:Matic® pumps are ideal for dual channel dispensing as low as 2 µL per dispense, as well as proportional metering of two fluids into a single fluid stream up to 4 L/min continuous flow.
