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.

Hybrid Reactor Solutions For Bioreactors And Catalytic Synthetic Chemistry

HEL ChemSCAN For Catalyst, Bio & Chemical Applications HEL offer reactors used for  “green” fuels (bio-diesel, bio-ethanol etc.), as well as bioreactors for cell and bacterial applications. These bio applications have a lot in common with high-pressure solutions for synthetic chemical screening and hydrogenation processes. The switch to 2nd and 3rd  generation bio-fuels (using biomass sources such as food-waste, stalks from crop, etc.) requires more extreme temperatures and pressures, not unlike heterogeneous catalytic processes. HEL’s unique position as both a bio and synthetic chemistry supplier is allowing the growing number of cross-over applications to be readily satisfied.

CATalyst Screening – EXPANDING The Product Range With The HEL PolyCAT

HEL products for Heterogeneous catalyst screening and highpressure process development at the moment go from the very basic (such as CAT7, 18  and 24) with each sample at exactly the same conditions and no data logging at one extreme and then HP Chemscan at the other end, which is  fully automated system with individually controlled sample conditions. The price difference between these two extreme is also very large and for this reason HEL is introducing the PolyCAT. This versatile new product is most definitely at the high automation and data logging end of the spectrum but some simplifications have enabled us to cut the price by some 30% compared to… Continue Reading
