XELSIUS Parallelsynthesis Reactor

Rapid and reproducible temperature profiles

XELSIUS Parallelsynthesis Reactor

Temperature profiles and data transfer via USB

A compact and fast reactor with 10 completely individually tempered and stirred reactor cells in the temperature range from -20°C to +150°C.
The space-saving device for parallel synthesis, reaction and process optimization, as well as for DoE (Design of Experiment) studies. Replacement for ten heating  cells, magnetic stirrers, ice baths, reactor cells and reflux condensers in only one device.
Save valuable space in the fume cupboard with clever and flexible solutions for operating and setting up the reactor.


Ten experiments in a single unit precisely, with completely and independently heating, cooling and stirring. Ideal for relieable results in solubility determination, catalyst supported reactions, DoE, crystallization experiments and PCR reactions. 

Rapid heating and cooling

High-performance peltier elements and an optimized cell design enable very fast and reproducible heating and cooling rates of over 30 K/min.

Easy to use in LAB mode

In LAB mode, simply set the temperature, stirrer and desired time or ramp and start immediately. With intuitive and clearly arranged features, you can start working productively with the XELSIUS after just a few minutes.



  • Temperature Studies
  • Parallel Synthesis
  • Crystallization Analysis
  • Solubility Profiling
  • Process Optimization
  • DoE Reactor

External Probes

Integrated sockets for external temperature probes in the reactor allow the liquid temperature to be recorded.

An optional turbidity measurement is ideal for monitoring during crystallization processes.
