Büchi Glas Uster - Laboratory Glass Reactor



There are 2 types of Glass Reactors:

Lab Glass Reactors for pressure applications

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.

Glass reactors for vacuum applications:

Glass reactors for vacuum applications allow operation at low overpressures (+1.0bar). They are used as stand alone reactors for single chemical process steps. When used for solvents, the complete set must be explosion proofed.



  • Laboratory, R&D (upscaling, small scale manufacturing)

Laborartory Glass reactors are made in Borosilicate Glass, it was developed in 1887 by Otto Schott and Ernest Abbe in Jena Germany, Borosilicate glass is also known as Pyrex, Duran or Jena Glass. Laboratory glass Reactors in Borosilicate glass provide several advantages:

  • 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.
