Nexus 3000 :Highly versatile syringe pump with instantaneous flow stabilization
Flow rates: 0.00001µl/min to 300ml/min
The Nexus series syringe pumps are high-end fluid delivery systems designed to tackle extremely tough applications with high rate variation sensitivities due to high pressure and viscosity dosing.
Standard Features:
•Color Graphic LCD interface
•RS232 port standard for computer control
•Infuse/withdraw rack
•Gradient/multistep pumping function
•Stall detection
Users can program in (without a PC):
Constant flows
Variable/Punctuated flow profiles
Gradient flows
Advanced loops
*Or mix and match in our highly flexible interface.
The Nexus 3000 syringe pump has high instantaneous flow stability with less than 8% of the nominal flow in nanoliter ranges for critical rate variation sensitive experiments. No other syringe pump system can come near these sub-microliter flows. Please ask SD about this capability and option.
This system has a variable transmission that gives this unit the largest flow range of any syringe pump on the market. This system can "shift gears" to reach low picoliter rate and high 500ml/min rates - almost a 12 order magnitude difference.
The Nexus 3000 syringe pump can be equipped with a push/pull rack and a 10-channel infuse/withdraw rack.
