Low Pressure Valve Qmix V EX

Qmix V EX Low-Pressure Valve

Zero Dead Volume

Qmix V EX valve modules combine high-performance multiport valves of the Rheodyne TitanEX series with a valve control unit in one compact housing. Rheodyne TitanEX valves are high-performance low-pressure valves with zero dead volume. They are particularly suited for:

  • Solvent selection
  • Fraction collection
  • Distribution
  • Process control / monitoring
  • IVD sample handling and preparation

Qmix Microreaction system with Qmix V valve module

Valve Module for all neMESYS and Qmix Systems

Modular and Expandable.

Qmix V valve modules let you expand your existing neMESYS dosing system or your existing Qmix flow-chemistry system with additional multiport valves, quickly and easily. Using the neMESYS interface and the neMESYS plug system, you can plug any number of valve modules into an existing system and thereby expand it and create completely new possibilities. You can also plug them into our neMESYS syringe pumps or Qmix micro-reaction modules to create your own complex dosing system or a complete micro-reaction system.

QmixElements Valve Plugin

QmixElements Valve Plugin

Switching, Configuring and Automating Valves

The QmixElements valve plugin gives you a good overview of all valve modules and lets you switch the valve position of any module quickly and easily. The names of all valves and even the names of each individual valve position can be selected freely to let you adapt them to the requirements of your particular application.

Script functions of the valve plugin make it possible to incorporate valve modules into complex Qmix scripts very easily. Valve position switching can be automated and synchronized with other Qmix modules.

Graphical Valve Display

Graphical Valve Display

All Information at a Glance

The software visualizes all valve types, including their specific appearance and their current valve position, letting you immediately identify the valve type and the current switching position of each valve. You can switch each valve to the desired position by clicking on it with your mouse or selecting it from the context menu.

QmixElements Software

QmixElements Software

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.

Qmix SDK Valve Library

Windows 32-bit / 64-bit DLLs

The valve library lets you incorporate a large variety of valves into your applications. It supports multiport valves as well as 3-2-way valves or squeeze valves. You can control 3-2-way valves of neMESYS syringe pumps or multiport valves of Qmix V modules, for example. All functions are supplied through a Windows DLL (32-bit / 64-bit), enabling simple and inexpensive integration into all Windows 32-bit or 64-bit development environments supporting the use of DLLs, such as:

  • Qt Framework + QtCreator
  • Microsoft Visual C and Microsoft Visual Studio .NET
  • Microsoft Visual Basic
  • LabVIEW
  • Matlab
  • Agilent VEE
  • Embarcadero RAD Studio with C++ Builder

Qmix SDK Valve Library LabVIEW Icons

Qmix SDK LabVIEW Kit

Full LabVIEW Integration

The LabVIEW kit lets you start controlling our valves immediately from your LabVIEW application. You can use virtual instruments (VIs) to access all of the important valve parameters and functions.


  • Clearly laid out grouping and color coding of VIs according to their function
  • Can be used with all other Qmix SDK libraries (pump, contoller, motion control...)
  • LabVIEW-conformant troubleshooting
  • Sample VIs for quicker introduction
  • Supports 32 and 64 bit LabVIEW versions

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.).
