Chemical process equipment consisting of glass lined reactors or mixing tanks with distillation overhead in borosilicate glass can be operated at full vacuum and low pressure. A large variety of chemicals can be processed in such plants due to the highly corrosion resistant materials used. The design varies between multipurpose productprocess specific set ups. Feeders and receivers are made of glass for smaller units and of glass lined steel for larger setups. Shell and tube type heat exchangers are built with inner tubes made of borosilicate glass, glass lined steel, silicon carbide, tantalum or other metals depending on process parameters and other requirements. Such reactor configurations are used for chemical synthesis, distillation, reflux distillation, solvent recovery, rectification and other processes.

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 installationtrouble shooting. Novan is very satisfied with the Büchi high pressure reactor and, in fact, we ordered a second unit during

Buchi magnetic stirrer drives (cyclone) are produced for the mixing of chemicals of low to high viscosity in pressurized lab reactors. Cyclone type magnetic stirrer drives have integrated motors and controllers for the stirrer rotation speed.

Mixing vessels are frequently used for stirring, dissolving, mixing, extraction and other processes in kilo-labs and pilot plants. Jacketed Glass reactors permit heat exchange for better dissolving and crystallization. Mobile mixing vessels can be transported with their content for further processing. They can also be equipped with condensers for vacuum distillation and operated as a reactor. Connection to Buchi reactors or other equipment is usually done with camlock adapters and flexible hoses.
