The patented UltraCLAVE achieves extraordinary performance capabilities by combining direct microwave heating in a high pressure reactor which acts simultaneously as microwave cavity and reaction vessel.
Only after ambient pressure is reached can the UltraCLAVE reactor be accessed for removal of processed materials.

The rack with individual reaction containers is secured on the reactor cover		The reactor body is lifted to dock with the cover, sealed and secured in place by side clamps
The reactor is pressurized with inert gas		A microwave program (controlling time-temperature-pressure-power) is selected and started
At the completion of the reaction, pressure is gradually released		The reactor body is lowered - processed samples can be removed

The heart of the UltraCLAVE

The cavity is the reactor

The high pressure steel reactor has a volume of 4.2 liters and an effective working volume of 3.5 liters with the PTFE liner installed. This is the largest volume single reaction vessel available to microwave chemists! Microwave energy from the system’s magnetron is introduced into the reactor through a special microwave-transparent port. Since the reactor and cavity are the same, the internal geometry is optimized for direct microwave coupling to materials in the reactor.
This design ensures maximum sample heating efficiency. The interior of the UltraCLAVE stainless steel reactor is protected by a special surface treatment for acid and chemical resistance.
