Static Sub-surface Reactors

Static Chamber - AstrobiologyOU

The AstrobiologyOU static reactors are used to study both abiotic and biotic processes within closed-system sub-surface environments of Mars and the icy moons, for example Europa and Enceladus. 


We have three static reactors that can be used at varying pressures and temperatures, each with different maxium volumes. A Haskel air intensifier is used to increase the pressure from a standard 200 bar gas cylinder to a high 345 bar, which is the equivalent of simulating the pressures at a depth of 3.5 km beneath the surface of Mars.
