A compact and fast reactor with 10 completely individually tempered and stirred reactor cells in the temperature range from -20°C to +150°C. This system is suitable for parallel synthesis, flow chemistry, reaction and process optimization as well as for performing DoE (Design of Experiment) studies. Save valuable space in the fume hood with a flexible and innovative solution. With XELSIUS you save time, increasing your laboratory throughput.
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.
By using the software 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 clicks.
Operate the XELSIUS where it is most convenient for you and your work processes. Simply place the touch monitor where you have space for it. On the back of the monitor there is a cross socket that can be easily adjusted by hand. This allows you to mount the monitor wherever you have a free stand rod in the fume hood; with the optional monitor extension cable you can even mount the operating terminal outside. The XELSIUS monitor stand is very helpful to place the monitor on a table or directly on the XELSIUS reactor. The versatility of the product stands out: it can be used inside a fume hood, mounted onto a robotic platform, coupled together as multiple units for mass sampling or simply operated free standing on a laboratory work surface.
Precise control of reaction temperature
Possibility to have an external temperature sensor for each reaction cell, allowing the sample temperature to be monitored and recorded.
Reliable even in rough conditions
XELSIUS System is integrated into a PTFE-coated housing. Cable connections and cables are also well protected with a PFA hose. This means they are well prepared for rough conditions in a chemical used fume hood. In addition, the easily adjustable inclination of the screen ensures that you can monitor even with unfavourable lighting conditions.
After switch-on, the XELSIUS immediately reports to LAB mode. You have a complete overview of the status of all ten cells and can immediately start with individual heating, cooling, stirring or temperature ramping, each cell separately with access to all essential functions.
… and discover the potential of PRO mode
It is simple to create more complex or multi-stage temperature profiles within PRO mode. Even cyclic temperature control procedures e.g. for biological processes could be realized quickly, saved and documented. The login function/user administration allows you to meet further GMP/regulatory requirements. PRO mode allows to display, save and export diagrams, temperatures and other parameters of each cell via USB. Each diagram is freely configurable. Scales, axis and displayed parameters could be chosen depending on the parameters you want to observe.
Create, save, load and export
XELSIUS system allows you to easily create the most suitable methods for your application and export the data you need to analyse.
An easy-to-integrate tool specifically developed for XELSIUS reactor. The innovative design prevents the annoying condensation of ambient air humidity. The evaporation losses of low-boiling solvents are significantly reduced. With the transparent cooling body you have an eye on what is going on inside. Stainless steel inserts guarantee an optimal heat transfer from the glass vials. The comparison shows that the reflux condenser dramatically reduces solvent loss in open septum-sealed vials (needle in septum) especially with low boiling solvents.
