HiClave™ 10ml to 20ml high pressure autoclave HiClave™ 100ml to 250ml high pressure autoclave
HiClave™ 200ml dual reactor system with controlled gassing and gravimetric dosing

HiClave™ high-pressure stirred-tank systems are a proven solution for high-pressure reactions, especially
on multi-phase systems.

They are available in the volume range of 10 to 250 ml, with a maximum pressure of up to 400 bar and
a maximum temperature of up to 400 °C. Thanks to the pure metallic pressure cap seal, the system
achieves a tightness that enables highly accurate measurements of gas consumption. Up to 7 media
connections are possible.

For reactors with over 100 ml capacity, the connections may be partially or fully routed on the
circumference of the cover flange. This allows for better handling and creates more space for peripherals.

Various heating/cooling systems, magnetic stirrers or magnet-coupled overhead stirrers and diverse
forms of gas and liquid supply systems are available.

They may be operated as single and parallel reactor systems. In addition to the standard configurations,
we offer customized systems tailored to your requirements.

The advantages

  • Direct sealing cover (without sealing ring)
  • Open scalable system
  • Simple Handling
  • Cooling option
