Nexus Features Overview


Syringe Pump- Nexus 3000
(Syringes not included)

Max Performance -

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. 



Instantaneous Flow Stabilization (Nexus 3000)-

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 Chemyx 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. 


Nexus 6000 High Pressure Syringe Pump - 

The Nexus 6000 is the most powerful high pressure syringe pump on the market with 450 lbs average pushing force up to 550 lbs max force. This system has a steel brace mechanism with a bolt lock ensuring long pump life span under high stress.

Standard Features:

•450 lbs avg force up to 550 lbs max force
•RS232 port for PC control 
•Gradient/multistep pumping function standard 
•Stall detection with audible alarm

Superb PC Connectivity -

RS232 and TTL come standard on every Nexus syringe pump. This system not only takes commands from PCs, it can also be controlled from PLCs and NI cards.

Commands are formatted in easy-to-understand ASCII text that can be sent by an array of programs from Labview, Labwindows, Visual Studio, MatLab and Hyperterminal, to name a few.

Every system also comes with a free Windows-based pump controller program for easy computer control.
