chemReactor CR – high-performance reactor system


chemReactor CR – high-performance reactor system

chemReactor CR – high-performance reactor systems for API synthesis, small-scale production and pilot plant applications

  • Glass, glass-lined steel reactor: 15, 30, 60, 100, 160, 250 liter
  • Pressure: -1.0 (FV) to +0.5 bar
  • Temperature: -60 °C (-90 °C) to +200 °C
  • Material: Borosilicate glass 3.3, glass-lined steel, PTFE, PFA, tantalum

A clean-room setup and other materials are available to meet your specific process requirements.

Performance and reliability are key issues in the explosion-proof design of Buchiglass reaction systems. The inert materials allow safe processing in a 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 chemReactor system consists of:

  • Reactor with solid jacketed glass-lined steel bottom stands for solid construction, excellent heat transfer, stable process conditions and temperatures and a glass section 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 CR type chemReactor is a multipurpose 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, nutsche filters/dryers, scrubbers or mixing vessels.
