In different research areas the optical consideration of processes or chemical reactions is of interest. In this context, the use of CO₂ is of special importance. Supercritical CO₂ can be used for high pressure extraction or decaffeinating of coffee. Another example is the oil exploration of deep layers of rock.

To observe nearly any reactions, RuboLab offers custom designed high pressure viewing cells. In addition to the structural design of the high-pressure cell, the choice of window materials are also custom selected. By doing this, optimal conditions for different applications (for example, spectroscopic analysis, IR, VIS-NIR) are guaranteed.
