Mid Pressure Syringe Pump neMESYS 1000N


Mid Pressure Syringe Pump neMESYS 1000N

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.

Your Benefits

  • 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

Unibody enclosure for maximum rigidity

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

neMESYS medium-pressure pumps boast many useful details and features that other pumps don’t have.

I/O connector for external sensors and signals

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.

Easy replacement of wetted parts of the syringe holder

Wetted parts of the syringe bracket can be exchanged very simply for cleaning or replacing contaminated parts.

magCHEX™ check valves - exchangable without tools

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 multi-channel medium-pressure syringe pump system

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.

Stainless steel syringes

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.

External pressure sensor and 2-way valve connected to neMESYS I/O interface via I/O distribution box

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.

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.
