Stirred lab autoclaves / Pressure reactors

Buchi laboratory autoclaves and pressure reactor systems are used for reactions under pressure such as hydrogenation, polymerization, catalyst research and materials research in chemical laboratories. They are also used for small-scale production. The autoclave reactor can be operated with various interchangeable glass reactors made of borosilicate glass 3.3 or high pressure-, high temperature reactors made of metal. Corrosion-resistant metals such as stainless steel, Hastelloy®, tantalum, titanium, zirconium etc. are used, see corrosion resistant materials. Powerful agitator drives with magnetic couplings ensure efficient stirring and mixing even at high viscosities.
