"My experience with H.E.L dates since 2005. During these years H.E.L was the provider of the most important lab equipment with the help of which I developed many different API pharmaceutical processes in the companies l worked for including Merck, Pfizer, and Theravance. The versatility of the automated lab reactors (AutoLAB), the ease of use of and the accuracy of the TSu and Simular systems, as well as the flexibility of the PolyBLOCK made my work much easier and accurate. I would like to mention the great relationship I established with the service engineers and the sales people at H.E.L. With their help I was able to customize the software and the hardware of the equipment to our specific needs. This readiness to accommodate each customer’s specific needs gives H.E.L the edge over their competitors and makes them the preferred vendor for pharmaceutical lab equipment. "

"I use a H.E.L. turbidity probe plus temperature probe for the determination of metastable zone widths and latent/induction time measurements in the study of crystallisation behaviour. The system is easy to use and very robust and records faithfully all the happenings. Even if one manages to do silly things, the data is still there and recoverable. The probes are neat and so can be used in small vessels, an advantage when dealing with valuable compounds. The amount of data that the computer will hold from a run is astonishing. The help from the technical team is always there, so we have been very pleased with our purchase. "

"With the polyblock 4 system significant time savings have been achieved compared to using conventional laboratory reactors while at the same time obtaining more information on the process studied. The system has given reproducible process control making it very useful in DOE experiments on a precise recrystallisation where variations due to operational error had to be minimised. Also with the flexibility in reactor size the process was run on smaller scale than previously reducing the demand for a valuable process intermediate. "

"We are happy to confirm that H.E.L has supplied us with two high pressure reactor systems with automation. These systems are used for the screening of catalysts and/or different reaction conditions in hydrogenation and hydroformylation reactions. We have been using one device with eight autoclaves during the last 8 years or so, and we are very satisfied with it. The handling and programming is quite easy. The graphical evaluation of data allows us to get an overview about the process in each autoclave. The cooperation and service provided by the employees by phone or e-mail is plain sailing. It is for this reason that we bought a second HP ChemScan with four autoclaves in 2010 which was upgraded recently to an eight-autoclaves-device. It allows a larger variation of parameters and also the graphical evaluation of the results has been further improved. "

"My role within the Green Chemistry Centre at the University of York (UK) is as Clean Synthesis Technology Platform Leader. Through this role I am currently supervising work being undertaken studying the application of heterogeneous catalysts and high-pressure gases for the conversion of biomass derivable compounds. As such our group has recently purchased three high-pressure reactors from H.E.L Ltd. To assist in the evaluation of our heterogeneous catalysts it is vital that stirring in the reactor vessel is control effectively and the reactor designs from H.E.L Ltd. achieve this by use of a suspended stirrer-bar system. As a result of our gas addition requirements some modification to the standard reactor designs were necessary, this being an area that H.E.L Ltd. were especially helpful in catering to our needs. From first contact with H.E.L (via Andrew Coleman), through reactor design and finally to reactor delivery H.E.L Ltd have been a pleasure to work. Throughout our interaction H.E.L Ltd. has proven to be knowledgeable, inventive and very efficient in supporting our research needs. I wholeheartedly support H.E.L Ltd. as a reliable, affordable, professional and helpful company for the design and manufacture of high-pressure equipment, and I certainly intend to use them again when such services are required.

"Three years ago we were developing a new catalytic process in collaboration with an industrial partner. It was essential to commission a reliable battery of glass reactors, built to our exact specification. We have decided to choose H.E.L’s AutoMATE II batch reactors array. We received professional advice, reactors built to specification, and a very thorough on-site training. The associated software is very intuitive and user-friendly. All issues occurring during the intensive use of the equipment were resolved quickly by the very helpful team at H.E.L. Last year, we have successfully progressed to a scale-up phase, for which we commissioned a custom-build AutoLAB reactor, with two exchangeable reaction vessels. Again, on all stages of ordering, manufacture and operation of the new reactor, the H.E.L staff were very helpful and made sure that their product was best suited to our needs. "
