High-Precision Dosing up to 200 bar
Precise dosing of viscous liquids
neMESYS medium pressure pumps are used for the precise injection of liquids into systems operating at higher pressure levels or with viscous liquids. They apply the benefits of our high-precision neMESYS dosing technology to pressure levels of up to 200 bar.
The powerful and highly accurate PID-controlled drive unit of medium-pressure syringe pumps ensures that the syringe piston is advanced extremely smoothly and allows for the creation of pulsation-free fluid streams in the nanoliter range (depending on the syringe being used). By using rugged stainless steel syringes, the drive can apply pressure levels of up to 200 bar.
- Accurate and pulsation-free liquid streams down into the nanoliter range
- Precise dosing of viscous liquids
- Support of high-pressure valves for the creation of continuous fluid streams
- Glass syringes or four sizes of stainless steel syringes are available
- Accurate dosing for pressure levels of up to 200 bar
- Modular system – multiple modules can be plugged together
- Combination with neMESYS syringe pumps or Qmix micro-reaction modules
- Comprehensive graphical operating software
- Programming libraries for Windows and LabVIEW
Made in one Piece
unibody housing for maximum rigidity
The housing of each individual neMESYS medium-pressure module is made in a high-precision process from a single piece of aluminum – creating the extreme rigidity of the housing. This prevents fluctuations of the flow rate that occur in other syringe pumps due to the bending of the housing in high-pressure and high-force situations.
An extremely accurate housing manufacturing process guarantees maximum precision with regard to flow rates and ensures the pulsation-free operation our neMESYS syringe pumps are known for.
Thought out down to the last Detail
non-return valves, i/o interface and much more
The integrated I/O interface allows the connection of external sensors (temperature, pressure) as well as signals to the pump that can then be evaluated by the software.
Wetted parts of the syringe bracket can be exchanged very simply for cleaning or replacing contaminated parts.
CETONI’s specially developed magCHEX™ non-return valves continue to switch reliably even at very small flow rates. They can be installed and removed without the need for tools.
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.
Precision Medium-Pressure Syringes
glass or stainless steel – your choice
Medium-pressure syringe pumps can be fitted with glass- or stainless steel syringes. These precision syringes are manufactured with the same care as our pumps and guarantee highly accurate fluid streams.
For the creation of higher pressure levels we recommend the use of our medium-pressure stainless steel syringes. These syringes are also suited very well for dosing aggressive media, since stainless steel is highly resistant to many aggressive substances.
Apart from standard glass or stainless steel syringes, we also offer Teflon-coated syringes or syringes made from special alloys.
Integrated I/O Interface
Expand your pump with additional functions
Using the integrated I/O interface, all pumps can be expanded with additional functions. For example, digital outputs can be used to switch external 3-2-way solenoid valves or our external ball valves. Through the analog inputs you can connect various external sensors, such as our external pressure sensors. And digital outputs let you trigger other devices in your lab. With the I/O distributor box you can easily connect several external accessory components.

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)
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.
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.
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.
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.
Laboratory automation platform
The QmixElements software is a comprehensive, plugin-based, modular software solution for the control of all cetoni devices via a common graphical user interface. The software consists of a core that provides the basic features and services, such as the application window, the event log or the tool bar.

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 RS232-PLC Kit
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 RS232-PLC-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.
