Buchi Reactor Systems & Pilot Plants sell "uniclave - lab pressure reactor"

This multipurpose pressure reactor system works with interchangeable glass and steel pressure vessels, with safety features that ensure secure operation under pressure. Its polycarbonate housing door lets glass pressure reactors run safely up to 12 bar while maintaining unobstructed visibility, and a high-torque magnetic stirrer drive provides precise mixing control with speed and torque readouts. The glass reactors resist acids strongly while enabling visual process monitoring. Uniclave is a compact, modular glass/metal pressure reactor system with a reactor volume of 0.5-1.0 liter, pressure range of -1 (full vacuum) to +60, temperature range of -20°C to +250°C, and construction in borosilicate glass 3.3 and stainless steel.
