miniclave - small pressure reactor

Laboratory pressure reactor system / Stirred autoclave for chemical research

Reactor volume: 100 to 300 ml
Pressure: -1 (FV) to +10 bar / 100 bar
Temperature: -20 °C to +200 / 300 °C
Material: Borosilicate glass 3.3, stainless steel, Hastelloy®, PTFE

Other materials, pressures & temperatures are available

This pressure reactor system is designed for the use of interchangeable pressure vessels in glass, steel, Hastelloy®, Teflon. Safety features guarantee safe reactions under pressure.

The glass pressure reactors ensure high resistance against acids, while allowing visual process control and monitoring.

  • Reactor or jacket temperature control
  • Limit temperature switch-off
  • Timeout function with switch-off
  • Menu navigation in German, English, Spanish & French



"The equipment is great to use! I really enjoy the quality of the stainless steel. Knowing that the vessel will be sealed as long as I operate under the designated safety measure makes me feel confident in the equipment! The vessel is a pleasure to work with and I have recommended Buchiglas to my colleagues.”
