Accurate volumetric dispensing of 4 microliters to 250 microliters
Positive shut with pressures less than 3 psi (except 73120-66 and -68 which has a 1 psi shut-off)
High cycle life - up to 20 million dispense cycles
Low power consumption
The Cole-Parmer pumps are factory set for discrete outputs ranging from 4ìl to 250ìl. The pumps can be cycled at up to 2.0 Hz for the 73120-0*, -1* and -2* series of pumps. The 73120-3*, -4*, -5* and -6* series can be cycled up to 1.6 Hz. Based upon the pump and cycle rate, flow rates can reach up to 25 mL/min. All the while the pump can maintain a high level of accuracy with a deviation from set-point being less than 1%.
The pumps are self-priming. Intially, the suction created by the larger pumps is sufficient to pull liquids from an unpressurized container located up to four feet below the. Once primed, the pump is able to maintain around 5 psi pressure.
Long life (3,000 hours) is built into each pump with a guarantee for up to 20 million actuations.
