"We are extremely pleased with our experience using Buchi equipment for our laboratory needs. Our project required precise control of volume, pressure, and temperature, and Buchi provided custom-made solutions that perfectly fit our requirements. The availability of glass pressure vessels was a standout feature, allowing us to visually monitor our polymerization reactions without venting the system. The equipment’s compatibility  with standard laboratory hot plates and fume hoods made integration seamless, and the 10 ml, 35 ml, and  100 ml vessels have been invaluable for scaling up our reactions. The equipment’s reliability, ease of use, and mention in peer-reviewed publications gave us confidence in our  decision to choose Buchi. Their solutions, including Swagelok® fittings, offered exceptional customization. The  assembly process was straightforward, and the system's excellent sealing has supported oxygen-sensitive  reactions effortlessly. The cooperation with Buchi and their local team partner was outstanding. Their responsiveness and  willingness to listen to our specific needs set them apart. We feel assured by the safety features, such as the  steel mesh containment and compatibility with blast shields. Overall, we highly recommend Buchi for their  innovative, high-quality equipment and excellent customer service."

"Our Buchi midiclave reactor provides precise control over temperature, pressure, and residence time. Paired with its powerful cyclone stirrer, this reactor ensures thorough mixing of the viscous reactants, facilitating the controlled conversion of the carbon-rich feed into targeted products. Additionally, the reactor is invaluable for numerous other batch reactions involving liquid and gaseous hydrocarbons such as hydro treatments. Its clear layout and easy-to-use fast action closure system make it an ideal tool for educational purposes, extending its utility beyond practical applications.”

“We are very satisfied with our Buchi versoclave system which allows us to perform various types of reactions (controlled and free radical polymerizations, hydrogenation…) thanks to the pressure and temperature ratings as well as the high torque stirrer. We have two reactor sizes (1L and 3L vessels) that are easily switchable and that we frequently use to study the influence of the reaction medium volume. The safety features, the ease of use, and the reactor lift are additional assets that make this apparatus indispensable within our R&D department.”

"Our requirements to Buchi were high from the beginning due to limitations, regulations and demanding processes. Thanks to their experience and flexibility, Buchi managed to solve all challenges and thus design and build the right equipment for us. Buchi also made every effort to develop the equipment within our budget despite the given complexity. For us it is therefore clear: Buchi was the right partner for us."

"The 100ml novoclave works great for my bench top scale. I love the idea that I can scale up to 600 ml at any time without having to purchase an entire new reactor. We use the novoclave for benchtop depolymerization reactions. Basically, we fractionate biomass into its monomeric components to serve as platform chemicals for other high value biomaterials or bioproducts. This employs water together with other solvents, acid or a base. The reactor vessel is well built to serve its purpose. It does not take up space at all which is great for a benchtop lab setting."  

"The equipment is great to use! I really enjoy the quality of the stainless steel. Knowing that the vessel will be sealed as long as I operate under the designated safety measure makes me feel confident in the equipment! The vessel is a pleasure to work with and I have recommended Buchiglas to my colleagues.” (about the miniclave)

"For carbonization, we have chosen the Buchi kiloclave Type 3E with a Cyclone 300 drive as stirrer agitator. The design of the reactor stand allows easy filling and emptying by single person. The individual components can be cleaned easily. Two stainless steel vessels with 0.5 liter and 5 liter are available as reactor vessels. For special reaction experiments in the acidic range by adding organic or mineral acids, a 1 liter reactor made of Hastelloy® is used."

"Our emulsion polymerization process is very difficult to simulate at the laboratory scale. The process runs at moderately high temperature and elevated pressure. High-shear agitation is critical to product quality. We have struggled to identify a pilot reactor that provided just what we need.  The available systems either cannot achieve the elevated pressure or are designed for extreme pressure, making them extremely bulky and costly. We had begun enlisting custom equipment manufacturers until we came across the Buchi kiloclave system, which was a good fit for us. With some simple, cost effective, customization, the kiloclave has proven to be the perfect pilot reactor for our process optimization."

“Buchi has a long history of providing high quality solutions for pharmaceutical applications. The proposed reactor was competitively priced and met our technical specifications. For Novan, the materials of construction (Hastelloy®), minimalization of dead volumes, pressure / temperature ratings, and vessel capacity were the most critical requirements. Advantages of Büchi include responsiveness of the local distribution partner, transparency during the equipment build in Europe, and effective installation / trouble shooting. Novan is very satisfied with the Buchi high pressure reactor and, in fact, we ordered a second unit during Q2 2017.”

"The Buchi customized versoclave met our specific reaction conditions for our polymer processing research. We will be using the equipment to scale-up our reaction from a few grams to kilograms. The system will be used to perform hydrogenations and melt processing of polymers. The installed reactor is best suit for our reactions because of it pressure rating, volume, max temperature rating, and the integration of a high torque stirrer which is needed to process the polymer. The equipment came assembled and the only installation required was to configure electrical connections. All doubts and inquiries were resolved through email. We are satisfied with the service provided by Buchi and with the customized approach they took to make a reactor best suited for our application."

“The most important requirement for us was the ability to produce scale-up experiments (kg quantities) of monomers, polymers, and other small organic molecules via different reaction conditions. Buchi was able to provide a flexible system compatible with both solution-based and melt-polymerization based methods. Distillation capability and the ability to stir viscous polymer solutions / melts is critical for our process. Buchi was able to custom design a Hastelloy® reactor to fulfill all of the above requirements as well as minimizing the footprint of the system in our walk-in fume hood. Very few manufacturers were able to provide this type of solution.” 

“Buchi equipment is constructed logically; it is easy to clean and very reliable. At Senn Chemicals, we appreciate Buchi’s competent staff and efficient service above all.”
