AutoLAB, University of Szeged, Hungary
"We were looking for a high pressure-high temperature reactor system with real time monitoring system to in-situ study our reactions. HEL came up with a system that suited our needs and budget. The reactor came with a software that records all the data during the process and it is easy to use. During installation we had a three-day course on the basics of the equipment and the software. "We got the service we asked for".

CAT 7, Teva Czech industries, Czech Republic
"Currently Teva is using Hel Cat7 hydrogenation system. It was effectively used for screening of hydrogenation catalysts and determination of optimal hydrogenation conditions. Our experinece with Cat7 system showed that it can significantly reduce the time needed for a selection of hydrogenation conditions, mostly by rapid identification of the most relevant screening hits for the further research and development process. In conclusion, Hel Cat7 was found to be very useful choice for our R&D."

HP ChemSCAN, University Joseph Fourier, France
''I have used the HP ChemSCAN II for a while now. My lab mates and I are using it for oxidation reactions using oxygen as the oxidant in organocatalysis. This apparatus has many advantages. You have a good control of the temperature and pressure and you can follow the gas uptake on the monitor with good accuracy. The software is easy to use, with all commands for one run resumed in one program. The interface of the software is pleasant looking with a good view of all parameters on each reactor, and the reaction can really be followed viewing the graphics, with the possibility of changing the scale of the graphs any time during a run. The reactors can be easily placed and removed without any problem, handling the reaction mixtures before and after the reaction is quite simple. People from HEL are keeping in touch with me, asking if everything is going well with the machine. If you are performing reactions with gas consumption and you want to be able to follow your reactions then you need HP Chemscan II.''

AutoLAB, Qatar University, Doha
''As a research active faculty member at Qatar University in chemical engineering with research fund that has a limited lifetime, I searched for specialist reactor suppliers around the world who would not only sell but also advise customers on their specific needs for the budget available. I was fortunate to select HEL in the UK and it started with an email query on a glass reactor for a tricky reaction system. That email was followed by a series of phone conversations to identify accurately my needs within my budget. I was particularly impressed by the speed of response and honest, impartial advice. I got what I wanted and when my research assistant encountered issues with the equipment during the warranty period, the spare parts were shipped very quickly, thus saving my research team precious time. HEL staff are professionals and trustworthy. As a research professor, I definitely recommend HEL for queries and purchases for intricate glass reactors for serious research work''

Custom Automated Synthesisers, Cranfield University, United Kingdom
''Cranfield University is working with HEL group on the design and manufacture of custom automated synthesisers for production of artificial ''Plastic Antibodies''. By combining the expertise from Cranfield University on the synthetic process with automation and custom fabrication know-how of HEL, a range of synthesisers were produced, including a new near-production prototype. Our experience with the new automated reactor/synthesiser showed that it can perform reproducible synthetic cycles under controlled conditions and with minimal operator input.''

High Pressure Vessels, University of York, United Kingdom
''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 HEL 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 HEL 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 HEL Ltd. were especially helpful in catering to our needs. From first contact with HEL (via Andrew Coleman), through reactor design and finally to reactor delivery HEL Ltd have been a pleasure to work. Throughout our interaction HEL Ltd. has proven to be knowledgeable, inventive and very efficient in supporting our research needs. I wholeheartedly support HEL 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.''

HP ChemSCAN, University of Rostock, Germany
'' We are happy to confirm that HEL 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. ''

Polyblock 4, Almac Group, UK
''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. ''

PolyBLOCK 4, BioCompatibles UK Limited.
The PolyBLOCK 4 is simple to use for all chemists and biochemists in our company. It allows us to carry out more reactions at a time, under very good temperature control. We also operate the PolyBlock overnight under pre-programmed procedures, to save a lot of precious time. We use different sizes of glassware in the same block, which allows us to investigate our chemistry at small scale, and then scale-up using the same equipment and pre-programmed procedure''.

Turbidity Probes, University of Southampton, United Kingdom
'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'

Various products, Theravance Inc, USA
''My experience with HEL dates since 2005. During these years HEL 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 HEL. 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 HEL the edge over their competitors and makes them the preferred vendor for pharmaceutical lab equipment.''
