When the application is more demanding in terms of dynamic range of flow rates, requires large volume infusion, or needs to pump against high back pressures then the Nexus series of pumps are the ones to choose. With a colour LCD screen and a simple, easy to understand user interface, the Nexus series are some of the most sophisticated yet affordable pumps on the market
The Nexus 3000 series syringe pump has variable transmission that gives this unit the largest dynamic range of any syringe pump on the market. Although this system has a very small step resolution, it is not limited to low speeds by fixed mechanical gearing, and can reach very high rates. The Nexus 3000 syringe pump can be equipped with a push pull rack and a 10 channel infuse/withdraw rack. The base system comes with a infuse/withdraw rack and multiple step/gradient pumping functions as standard. RS232 control is also standard on this system
The Nexus 6000 is the most powerful high pressure syringe pump on the market with 450lbs ( 204.5Kg) average pushing force up to 550lbs (250Kg)max force. This system has a patent pending steel brace mechanism with a closed bolt lock ensuring long pump life span under very high stress.If you need to infuse against very high back pressure such as with micro-channel experiments or infuse into high pressure reactor vessels, the Nexus 6000 is the pump to choose.
