xelsius, 10 reactions – one device

Easy to use with multitouch user interface

Fast heating and cooling / flexible reaction setups

Ideal for Drugdiscovery, MedChem, CombiChem and reaction optimization
Parallel synthesis from -20°C to 150°C in 10 individually controlled reaction cells
Synthesis reactor with 10 individually controlled reactors

xelsius is a robust and very fast synthesis reactor with 10 completely individually temperature-controlled and stirred reactor cells in the range from -20°C to +150°C.


The right choice for chemists in the field of

  •     parallel synthesis,
  •     reaction and process optimization,
  •     solvent screening and crystallization,
  •     drug development,
  •     as well as for conducting Design of Experiment (DoE) studies.


Achieve reproducible results at small reaction volumes from 0.5 ml to 30 ml, simplified operation while maintaining high experimental quality. Combined with modern data management features, you are able to make the most efficient use of valuable working time, chemicals and energy.

Precise, reproducible, reliable

The xelsius replaces ten heating blocks, magnetic stirrers, ice baths, reactor cells and reflux condenser in just one unit.

Save valuable space in your fume hood.

Specified temperature profiles can be realized in a controlled, precise and reproducible way, from 0.1°C /h up to 50°C /min.

xelisus creates the basis for reproducible and reliable reactions and as another result, faster and better communicable values out of your experiments

With clever, flexible and practically proven solutions for operation and set-up of the reactor, it offers a wide range of possibilities to implement your individual application in a scale from 0.5 – 30 ml.
