NE-1000 Single Syringe Pump

The NE-1000 series of syringe infusion/ withdrawal pumps are easy to use, set syringe diameter, enter rate and press start, yet allow complex pumping sequences to be programmed directly from the pump without a computer. Programming functions include rate, increment rate, decrement rate, stop, jump to phase, program selection input, loop start -end- repetition, pause, external trigger, TTL output.   

Examples given in the instruction manual includes 2 step rate changes, repeated dispenses, pause, ramping flow rate,dispenses with external synchronization, control from a high-low pressure sensor, automated continuous dispensing with syringe refill.
