HEL CAT 7 Design Improvements

Change In Design For CAT 7 Cold fingers have been removed (unscrewed) and silicone seals no longer used. Instead, special PTFE plugs are placed in each vial. This is the only change. Why Change?- The Benefits Solvent loss from vials during an experiment is much reduced and reproducibility is improved. Also, chemical compatibility is improved by removal of silicone seals and use of only PTFE. The operation remains simple. Older CAT 7 Units Existing CAT7 units can be updated easily. Cold fingers must be unscrewed by the user (easily done by hand) and a set of PTFE plugs purchased.    

Rapidly Evaluate Catalysts & Optimize Reaction Conditions

With the HEL CAT 7, CAT 18, CAT 24, PluCAT, DigiCAT products for Rapidly Evaluate Catalysts & Optimize Reaction Conditions

One challenge faced by researchers in catalyst development is the need to quickly evaluate different catalysts and optimise reaction conditions. However, accessing affordable, high pressure, high temperature screening devices is equally challenging. The HEL CAT blocks: |Provide an affordable, entry level range of catalyst research tools. |Are available in 7, 18 or 24 vial configurations the CAT blocks allow primary catalyst screening and basic process optimisation at relatively low cost. |Can be used with conventional hotplate stirrers and all gas and pressure fittings are preinstalled. |Are widely used successfully at many Universities both as research and teaching tools. |Allows to undertake rapid parallel catalysis and thereby facilitate quicker downstream analysis.… Continue Reading

See Our Webinar: Faster and Better Process Development Using Parallel Reactor Platforms and DoE

This webinar focuses on the use of multiple (parallel) reactor platforms, which is becoming an established practice in pharma and other sectors as well as the use of DoE to direct the experimental effort and analyze the data. The webinar also highlights the results of many different process development studies to illustrate the range of parallel reaction instruments available. Examples from synthetic organic chemistry in general, as well as heterogeneous catalysis (including hydrogenation in flow reactors) and crystallization studies, are used to describe the benefits of these techniques.

The Next Step In Flow Chemistry Under Pressure : The FlowCAT SA

Contrary to popular belief, “Flow Chemistry” has extensively been used in small scale chemical production for decades, especially for chemistry under pressure. The HEL FlowCAT is a bench-top platform enabling continuous flow heterogeneous catalysis for use in applications including hydrogenation, carbonylation, oxidation and is widely used in the pharmaceutical and fine chemical industries. In response to customer requests, a lower price platform is now being launched – The FlowCAT SA. The FlowCAT SA provides a more focused set of working conditions, and the control is semi-automated (hence “SA”). The compact mechanical design is of the same quality and robustness (of the original FlowCAT), but working pressure and the temperature are… Continue Reading
