Pharmaceutical process technology is using Borosilicate Glass due to several reasons. Borosilicate glass was developed in 1887 by Otto Schott and Ernest Abbe in Jena Germany. It is also known as Pyrex, Duran or Jena Glass. Glass reactor systems provide several advantages due to the Glass factor:
- wide operation temperature range
- very low thermal expansion (linear over a wide temperature range)
- It’s hydrophobic characteristic makes it easy to clean the complete
- chemical or pharmaceutical reaction unit
- The inert attitude is another important factor, and at the other factor is obvious - it is transparent.
These are the main reasons for the use of Borosilicate glass in chemical processing plants or single glass reactors used in chemical research, especially in pharma research.
Buchi offers stand alone glass reactors for pressure applications in the lab and Pilot Plant, kilo lab reactor systems in glass / glass lined steel for process development as well as for productions sites.
There are 2 types of Glass Reactors:
- Glass Reactors for pressure applications (max. 12 bar)
- Glass reactors for mainly vacuum applications (full vacuum -1 bar to +1 bar)
| Glass pressure reactors or stirred Lab autoclaves are mainly used in chemical research. Glass pressure reactors are corrosion resistant and allow the chemist to visually observe the reaction. Safety measures are integrated in the systems to allow safe operation under pressure. Our Pressure Reactor systems allow the use of different reactor vessels within the same unit, they are interchangeable against metal vessels (pressure ratings > 12bar), if needed with sight glass. Please refer to our page about pressure reactors | Glass reactors for vacuum applications allow operation at low overpressures. We differentiate 3 types of glass reactors: «minipilot» with reactor volumes of 5 – 15 liter «chemReactors» or Pharma Reactors with 15 – 250 liter Glass / Glass lined steel reactor volume Glass Reactors with 10 to 200 liter reactor volume |
Complete sets of reactor systems consist of a glass- or (glass lined steel reactor) with glass overhead for distillation purposes. The glass overhead is built by «büchiflex» glass compents.
Reactor systems from 250 liters up to 4000 liters in kilo labs use glass lined steel reactors with glass distillation overhead. These glass overheads with components up to DN 600 are mainly customized setups for specific applications. For such units, we offer specific engineering services.
