Selection Guide

Glass-Reactors---JGR-Series.jpg

Glass Reactors - JGR Series

  • Laboratory and small pilot scale (1 L – 200 L)

  • Primarily vacuum and atmospheric pressure applications (-0.1 MPa – Atm)

  • Outstanding resistance to most acids and solvents

  • Easier visual observation of reaction, mixing, and phase changes but requires careful

  • Borosilicate Glass 3.3 offers excellent thermal stability and performance (-80°C – 250°C)

Stainless-Steel-Reactors---SR-Series.jpg

Stainless Steel Reactors - SR Series

  • Laboratory to production scale (1 L – 10,000 L)

  • Suitable for vacuum, pressure, and high-pressure reactions (-0.1 MPa – 0.6 MPa)

  • Excellent corrosion resistance with 314/316L for most industrial applications, with material grades selected according to process chemistry

  • Durable, easy to maintain; process monitored through instruments or sight glasses

  • Suitable for a wide range of heating and cooling applications (-20°C – 250°C); Extended temperature ranges available upon request.
