High Pressure / High T° Reactors
Batch reactors with bolted yoke or clamp and screw.
For applications requiring temperatures above 250°, or pressures above 300 bar, the autoclave type design with plug and screwed head is no longer suitable, either because the force exerted by the pressure is not compatible with the strength of a thread, or because the temperature imposes low compressible seals which therefore require a precise torque.
In this case, TOP Industrie designs and manufactures autoclaves with bolted heads, with a sealing ensured by Kalrez, PTFE or metal seals. In the same way as for the quick-closing autoclaves, TOP Industrie realizes an almost infinite range of diameter/height torques allowing the user to choose the volume and the H/D ratio best adapted to his experiments.
The whole range of accessories and peripherals useful to the world of research and university or industrial experimentation is available.

Hydrothermal Synthesis Reactor HP/HT° :
This range of autoclaves with metal/metal seal has been designed for high pressure and high temperature use, especially in petrology, volcanology and geology.
It allows to study the behavior of rocks, the interactions between the material and its gas/liquid environment in extreme conditions. The samples are either placed directly in the compression fluid or placed in sealed gold capsules.
The pressure is generated either by an aqueous medium using Henri's curves (P.V.T); or by pressurizing the sample directly into gas using a booster (up to 3500bar) or a gas multiplier (up to 7000bar).


A recent collaboration led by Karine Devineau from équipe˝ Magmas et fluides profonds˝ of the CRPG Nancy, enabled the realization of a parallel hydrothermal synthesis unit, equipped with 3 HP 3000bar/HT° 800°C fast quenching autoclaves and a 3000bar gas generation module.

Exchanges between the deep envelopes of our planet and the surface are largely associated with the formation and movement of magma or deep fluids. The movement of these liquid phases is closely linked to the Earth's internal dynamics (plate tectonics, convection, crustal growth and recycling), to its differentiation and the creation of heterogeneities. The "Magma and Deep Fluids" program aims to contribute to the understanding and quantification of the processes involved in these exchanges by focusing on three points: magma evolutionary processes and their kinetics; the modes of magma transfer between the mantle and the crust; and finally the origin, distribution and role of deep silicate and non-silicate fluids. The approach is multidisciplinary, closely combining experimental petrology, field observation and elementary and isotopic geochemical measurements at different scales.
