Compact Positioning System rotAXYS

3D Compact Positioning System

Expand your Qmix flow chemistry system with sample handling

Our rotAXYS miniature positioning system is the optimal solution for applications in which small items such as pipetting tips, tube ends or syringes have to be positioned in a tight space. It is perfectly suited for:

  • the processing of single well plates or microscope slides
  • automated serial sample storage
  • pipetting liquids
  • manual positioning tasks

Due to its small size and compact dimensions, this device is your optimal solution for work in tight spaces, such as laboratory tables and workbenches.

Qmix system with ceLED LED array on rotAXYS sample handler

Modular & Expandable

Build your own Fluid Handling System

Using our standard neMESYS interface, rotAXYS sample handlers can be connected to all other CETONI devices and used to expand them. For example, if you want to irradiate micro-titer plates during fluid handling, you can simply use our ceLED LED arrays. If you want to dose small amounts of liquid into micro-titer plates, you can connect the rotAXYS sample handler to our neMESYS syringe pumps or Qmix valve modules.

Of course, you can also expand an existing neMESYS dosing system or Qmix micro-reaction / flow chemistry system with rotAXYS sample handlers. Simply configure your system in our QmixElements software and start working.

QmixElements Software

Positioning Systems perfectly under Control

The rotAXYS / neMAXYS plugins for QmixElements give you full control over your rotAXYS and neMAXYS positioning systems. The easy-to-use and clearly laid out user interface makes manual positioning easy. To traverse the systems, simply click a position on the screen or click on a container (well, tank) in the graphic display.

The current position of the positioning system, the current configuration of your worktable, including all containers and micro-titer plates as well as all other important parameters are shown to you in a clearly laid out graphical user interface.

Powerful script functions let you master even challenging positioning tasks conveniently through drag&drop. Using this form of graphical programming, you can automate processes without a lot of training.

Graphical user interface

Graphical user interface

Intuitive and easy to use
  • Positioning map for convenient XY-positioning by mouse click - continuous zoom
  • Simple positioning by clicking wells, tanks or other containers
  • Z-panel for z-axis positioning
  • Control pad for manual control of x, y and z-axis
  • Visualization of all current parameters (position, status…)
  • Fast insertion of the current position into positioning scripts with a single mouse click
  • Display of all sample containers (corrugated panel, well, beaker…) as clickable elements
  • Continuous enlargement using the mouse wheel

Powerful Script Functions

Automation through Drag&Drop

Integrated script functions, such as move to XY, move z or move to container, let you incorporate rotAXYS and neMAXYS positioning systems conveniently into the QmixElements scripting system

With this type of graphical script programming you can create complex positioning scripts quickly and easily using drag&drop. In this way you can scan all wells on a well plate with only 3 script functions, for example.

Full 3D-Mouse Support

Intuitive One-Hand Control

We support 3D input devices made by 3D Connexion (3D mouse). This makes it possible to intuitively control all axes of neMAXYS and rotAXYS devices with one hand. In this way you can control your systems with such precision and sensitivity that it feels as if you were moving them with your own hand.

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.

Integration into custom applications

Easier than ever

The rotAXYS / neMAXYS positioning systems offer unprecedented possibilities to you for integration into your applications. Whether you develop standard Windows applications or if you want to program in LabVIEW - we deliver the suitable libraries for that purposes. Other devices often are equipped with RS232 interfaces and use proprietary communication protocols. We provide you with up-to-date interfaces like USB or CAN, standardised open communication protocols like CANopen and comprehensive and comfortable programming libraries. Simply connect the positioning system to your PC, install drivers and programming libraries, switch on the device and you are ready to go.

Interfaces neMAXYS

  • USB 2.0 / 1.1
  • CAN max. 1 Mbit / s
  • RS232 max. 115200 bit / s
  • Ethernet (optional)


Interfaces rotAXYS

  • USB 2.0 / 1.1 (Adapter)
  • CAN max. 1 Mbit / s
  • Ethernet (Adapter)


CANopen logo

CAN and CANopen (DS402)

Standardized device parameter access

The positioning system implements the CANopen device profile DS402 - Drives and Motion Control. Each single axis can be accessed by CANopen applications via the integrated CAN interface. The use of CAN bus and the standardised higher layer protocol CANopen ensures the extensibility of the positioning system.

Up to 11 positioning systems can be added to each other and controlled via one single USB interface. Extern CANopen modules like digital I/O modules, analog I/O modules, peristaltic pumps, neMESYS syringe pumps, regulating modules or heaters can be added flexibly.

Qmix SDK Motion Control Library

Windows 32-bit / 64-bit DLLs

This library contains all functions for the integration of multi-axis positioning systems and individual axes in your applications. This lets you integrate all cetoni positioning systems, such as rotAXYS and neMAXYS, into your systems and applications in a short time and at low costs. The API offers you functions for:

  • Positioning individual axes
  • XY-positioning of axis systems
  • die Initialization
  • Reading of position and speed values

All functions are available through QmixSDK - motion control API as Windows DLLs (Dynamic Link Libraries). These DLLs can be integrated into any Windows development environment supporting the use of DLLs.

  • 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.).
