Performance and reliability are key issues in the explosion proof design of Buchi glass reaction systems. The inert materials allow safe processing in an inert atmosphere of a wide range of solvents and acids in a completely sealed glass reaction system under full vacuum. Multiple chemical reaction steps are performed safely in the same setup.
The system consists of:
Reactor, solid jacketed full view glass reactor to easily improve and control chemical reactions by visual observation.
Distillation glass overhead built with buchiflex components (unique flexible ball - socket joints) for multiple, reliable processes under full vacuum.

The BR/GR type chemReactor is a basic pilot reactor system for chemical process development, scale-up, process simulation and kilo-scale cGMP production in batch and semi-batch operation.

We produce complete solutions for chemical processing: Reactor systems including accessories like sampling devices, pH probes, rectification columns with structured packing, process monitoring and control as well as integration of auxiliary equipment such as temperature control units, nutsch filters / dryers, scrubbers or mixing vessels.
