NE-4000 2-syringe programmable pump
The NE-4000 from New Era / ALA Scientific is a pump with two syringes (up to 60 mL each, compatible in different sizes), allowing synchronised or independent infusion or withdrawal (“Push-Pull”), with high precision and advanced programming.
Features of the NE-4000 2-syringe pump
- Capacity for two independent syringes of up to 60 mL each (up to 140 mL partially filled).
- Ultra-large flow rates: from ~1.4 µL/h (1 mL) up to 7,515 mL/h (60 mL) depending on syringe used.
- Programming of up to 41 phases (flow rate, volume, pauses, external triggers, alarms).
- Push-Pull function for continuous dual-synchronised infusion via special cable or independent operation.
- Simple keypad interface with display, stand-alone operation or control via bi-directional RS-232 and TTL I/O.
- Automatic motor lock detection, non-volatile memory, automatic restart, configurable audible alarm.
