Low Pressure Syringe Pump neMESYS 290N


Low Pressure Syringe Pump neMESYS 290N

Pulsation-free, modular and accurate down to the Nanoliter range

For the most demanding applications in research and industry

neMESYS precision syringe pumps are ideally suited for the creation of extremely uniform and pulsation-free fluid streams in the range of milliliters and nanoliters per second as well as highly accurate dosing of miniscule amounts of fluid. The syringe pump’s PID-controlled drive system ensures that the piston advances very smoothly, preventing stick-slip effects and guaranteeing a high degree of accuracy and lack of pulsation in the fluid streams created.

The syringe pump’s PID-controlled drive system ensures that the piston advances very smoothly, preventing stick-slip-effects and guaranteeing a high degree of accuracy and lack of pulsation in the fluid streams created.

The universal syringe receptacle on the neMESYS syringe pump offers you a lot of freedom when choosing the syringes you can use. You are therefore not limited to a specific manufacturer or type of syringe. Using an optional valve, the syringe pump can be switched from reagent uptake to reagent delivery during operation, without switching syringes or tubes.

Your benefits

  • Pulsation-free dosing of fluid streams
  • Modular, expandable system
  • Universal receptacle for syringes with an outside diameter ranging from 6-30 mm
  • Integrated and exchangeable 3-2-way valve
  • Comprehensive software package with SDK and LabVIEW support
  • Operating modes: sequential, parallel and continuous

One pump - thousands of possibilities

Suitable for your application

If you work in low pressure ranges and want to dose with high precision and without pulsation, you should choose the nemesys low pressure syringe pumps. The areas of application extend far beyond bioprinting, state-of-the-art lab-on-a-chip applications and applications in compartmentalized flow.

Creating microfluidic multipoles

Thomas Gervais et al. liberate fluids from microchips and lay the foundations for the future of microfluidics with their research on "open space" applications. The experimental demonstration of the principles exposed required the use of up to 12 Low Pressure Syringe Pumps neMESYS 290N.

Microorganisms in the compartmentalized flow

Mankind has reached a point where new active substances are urgently needed, as various bacterial strains have developed resistance to the known antibiotics and can no longer be used to combat them. The role microfluidics and the so-called compartmentalized flow can play in the search for new active substances is discussed in this article of the #CETONIacademy.

Droplets in QmixElements

Droplet-based high-throughput screening has never been easier

Postek et al. nicely demonstrated an automated high-throughput screening for MIC determination (minimal inhibitory concentration) of an antibiotic in nanolitre droplets for different E.coli concentrations. With the help of the specially developed DropChop chip, different physically separated compartments can be generated. With the resulting ultra-small sample volumes, comprehensive test series can subsequently be carried out with maximum efficiency and large scaling.

Modular & Expandable

build your own dosing system

Individual syringe pump modules can be connected to other neMESYS syringe pumps or Qmix micro-reaction modules to create a complex dosing system or a complete micro-reaction system, simply by plugging them together. This allows for the pulsation-free creation of multiple, independent fluid streams at different pressure ranges – synchronized and accurate down to the nanoliter.

In combination with the comprehensive software package, high-precision neMESYS syringe pumps offer you previously unknown possibilities in high-precision dosing.

High-Precision Syringes

Glass or stainless steel – Your choice

A highly precise drive unit and the precision of the syringes used are of equal importance when it comes to accuracy and pulsation-free operation. Our precision syringes are manufactured with the same care as our pumps and guarantee highly accurate fluid streams. Low-pressure syringe pumps can be fitted with glass- or stainless steel syringes.

QmixElements neMESYS Plugin

neMESYS Plugin for QmixElements Software

Pump Software that is Fun to Use

The neMESYS plugin incorporates all neMESYS syringe pumps into the QmixElements software suite. This plugin provides you with powerful pump features, which you won’t find anywhere else. The clearly laid-out, attractive user interface gives you a good overview of all important parameters, such as syringe filling level, configured syringes, dosing direction, current flow rate, current valve position or the current pressure.


Simple, Intuitive and Powerful
  • Graphical display of syringe size, filling levels and valve position
  • SI units for volumes and flow rates are freely selectable (ml, nl, ml/s ...)
  • The syringe wizard guides you through the configuration of new syringes
  • Real-time display of current values, such as flow rate, syringe filling level or dosed volume
  • Coloration of the syringe depending on the movement direction (orange = filling, blue = dispensing, gray = stopped)

QmixElements pressure indicator

Graphical Pressure Display

For more Safety and a better Overview

The pressure display for neMESYS syringe pumps lets you keep an eye on the pressure of integrated pressure sensors at all times. The display elements visualize the current value of the pressure sensor in the form of a digit as well as a bar diagram. The display also uses different colors – green (low pressure, yellow (medium pressure) and red (high pressure) – to give you a good idea of a module’s pressure range, so you can detect critical conditions and react quickly.

Configuration dialog for syringe selection and configuration

Easy Syringe Configuration

Selecting existing Syringes or Creating your Own

You can choose from a broad selection of existing syringes or use the syringe wizard to quickly configure your own. Simply select the inside diameter, the piston stroke and the syringe material for a new syringe and you are done. The software will then show you your syringe with the selected material and the thickness and length you selected.

QmixElements Safety Monitoring Dialog

neMESYS Pressure and Analog I/O Safety Monitoring

For more Safety through automatic Alarm Reaction

The analog I/O monitoring feature lets you use any analog inputs or pressure sensors as safety switches for neMESYS syringe pumps. In dangerous situations, such as exceeding a certain maximum pressure or temperature, you can stop neMESYS pumps automatically, shut them off or simply release an alert message. The inputs (pressure, temperature…) as well as the alarm response (stopping the pump, pump shut-down, warning…) can be freely selected by the user.

neMESYS Scripting System

Script Functions

Graphical Programming of complex Processes

neMESYS pumps are fully supported by the QmixElements script system, letting you program your own complex dosing processes in a very short time through a graphical interface using drag&drop. With powerful script functions you can very quickly implement requirements, such as time-controlled dosing with multiple pumps or the creation of flow gradients over a certain time period. In combination with other Qmix or neMESYS devices, this lets you set up complex processes and tests in your laboratory.

Qmix SDK

Qmix Software Development Kit (SDK)

For integration of cetoni devices into custom applications

The Qmix SDK is a powerful software package that allows developers to integrate their Qmix system and its various modules into their applications. Central to the Qmix SDK are device-specific libraries that provide the programming interface (APIs) for each Qmix module (neMESYS pumps, rotAXYS and neMAXYS positioning systems, Qmix IO, etc.).

neMESYS Integration Kit

Connection to PLC or microcontroller controls via CAN or RS232

All our pumps have CAN and RS232 interfaces and can be connected easily to PLCs or custom control solutions. Many control systems, such as e.g. the PLCs from Beckhoff, B&R or WAGO, already have CANopen interfaces included for direct connection of neMESYS CANopen pumps. Other PLCs, such as e.g. Siemens S7, can be made CANopen compatible with certain hardware modules or CANopen gateways.

Alternatively, you can always use the RS232 interface for connecting the pump to your PLC. In our neMESYS Integration Kit you will receive our open source RS232 C library and a comprehensive documentation package for connecting the neMESYS pumps to PLCs or custom control solutions.

You get in the kit:
