polyclave – lab pressure reactor


polyclave – lab pressure reactor

polyclave – laboratory pressure reactor system – comfortable and simple operation

  • Reactor volume: 0.25 to 5.0 liter
  • Pressure: -1 (FV) to +60 / 200 bar
  • Temperature: -20 °C to +250 °C
  • Material: Borosilicate glass 3.3, stainless steel, Hastelloy®

Other materials, pressures & temperatures are available.

The polyclave is a multipurpose pressure reactor system designed for the use of interchangeable glass and steel pressure vessels. Safety features guarantee safe reactions under pressure.

The glass reactors ensure high resistance against acids, while allowing visual process control and monitoring. This is also possible under high pressure by using steel pressure vessels with sight glasses. Various low to high torque magnetic drives ensure efficient mixing and stirring low to high viscosity process media as well as excellent heat transfer.

The modular setup of the Buchiglas polyclave system allows changing or upgrading for new tasks at any time.

With fast action closure and reactor lift it becomes very easy to operate also heavy metal pressure vessels. A wide range of accessories for feeding of liquids, solids, gas and others like catalyst baskets etc. are available – talk to us to define the right setup for your specific need.
