H-Cube Mini Plus™

Safe, simple, and affordable hydrogenation

The newest member of our H-Cube Series of hydrogenation reactors, the H-Cube Mini Plus™, was developed as a safe, powerful, and affordable reactor. It comes with an automated drying system, which makes it even easier and more robust. The system allows water sensitive reactions to be performed and increases the simplicity of how reactions take place.

Hydrogenation is one of the most important reactions in chemical synthesis, but the hazardous nature of hydrogen has restricted its use. The H-Cube® and H-Cube Pro™ have already eliminated the dangers associated with hydrogenation through the use of in-situ hydrogen generation and the handling of pyrophoric catalysts by filling them in sealed catalyst cartridges. This technology has been adopted by the leaders in the pharmaceutical, flavour and fragrance, fine chemical and agrochemical industries.

The H-Cube Mini Plus’s hydrogen generation system can be easily turned off to allow heterogeneously catalyzed non-hydrogenation reactions to be performed as well such as C-C coupling reactions.

The H-Cube Mini Plus™ is as a compact and easy to use instrument which meets with the budget of academia.


  • Hydrogenation without cylinders
  • No catalyst filtration
  • Fast Reactions
  • Easy to Use
  • Academia Budget Compatible
  • Built in video tutorial
  • Automated hydrogen drying system

How does it work?

  • Hydrogen is generated through electrolysis of water.
  • A continuous flow of hydrogen and solvent are passed through the reactor from ambient conditions up to 100 °C and 100 bar.
  • When desired parameters are achieved, solvent is changed to reactant
  • The hydrogen/compound is passed through a packed column containing solid catalyst (CatCart®), where the reaction takes place. The product leaves the column, but the catalyst stays behind.
  • Reductions vary in scale from 10 mg-10 g

Can the H-Cube Mini Plus be used by undergraduate students?

Yes, chemists at any level can easily learn how to use the H-Cube Mini Plus within minutes. The H-Cube Mini Plus is the first instrument helping the users with embedded support videos about general use and troubleshooting.

Can I get any help in making the learning process and the implementation of the technique into the practical session faster?

Yes, you can either contact our chemistry team for advice by email at askthechemist@thalesnano.com, or we can provide you the Practical Lab Book for the H-Cube Mini Plus.

I am not working in academia, can I order an H-Cube Mini Plus?

No, the H-Cube Mini Plus is developed specifically for academia in order to give the teachers and students an affordable possibility to teach and learn more about flow chemistry and safe hydrogenation so that students can meet the industry requirements employers will be looking for upon graduation. Please respect our efforts in this project and leave this version of the H-Cube Series to them, click here to see more details on the H-Cube Pro, which is really for You.

Are the standard CatCart sizes available for the H-Cube Mini Plus?

Yes, both the 30 mm and 70 mm sizes are compatible.

Is the H-Cube Mini Plus compatible with the Autosampler systems?

No, the system will not be compatible with ThalesNano AutoSampler system.

Can you react other gases or perform other non-hydrogenation chemistries on the H-Cube Mini Plus?

The system is able to work with the modules only in their stand alone working mode lacking any software control.
