HiClave™ High Pressure Process Plant

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

They may be supplied in a volume range of 10 to 250 ml, with a maximum pressure of up to 300 bar and a maximum temperature of up to 300 °C. Thanks to the pure metallic pressure cap seal, the system achieves a tightness which enables highly accurate measurements of gas consumption. Up to 7 media connections are possible.

For reactors of 100 ml content and larger the connections may be partially or fully routed around the outside of the cover flange.

This enables better handling and creates more space for peripherals. Various heating/cooling systems, magnetic stirrers or magnet-coupled overhead stirrers and varied 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, you can have systems manufactured especially to suit your demands.

Standard Systems

HiClave™ systems are built up in a modular manner. The components described below form the basis for versatile pressure reaction systems. They can be adjusted to suit the demands in each case and upgraded with the aid of the auxiliary modules and components.

10 ml and 20 ml Reactors

10 ml and 20 ml reactors have a cover with a union nut and a central media connection with a crosspiece. The centre connection of the crosspiece is occupied by the interior temperature controller, those at the side normally with the media connection and manometer.
The reactors are tempered using a magnetic heating stirrer with a heating block and stirred using a magnetic stirring rod.




Hydration module

The VL-HICLAVE-HYDR hydration module enables a complete hydration process to be carried out including inert gas rinsing and leak testing of the reactor without any manual Intervention. As a result, no-one has to be present in the high-risk area during the time in which the reactor is under pressure. For this, inert gas is applied to the reactor up to an adjustable pressure and then aerated. This rinsing cycle may be repeated as often as desired. Subsequently, a pressure check with inert gas is performed. The duration of the check and the tolerance for passing the test are freely selectable.
