System Design
This laboratory system is used for the precise determination of the solubility of specific gases such as carbon dioxide, hydrogen, and methane in various liquids. For this purpose, a flat stainless steel plate reactor (30 mL) can be filled with the desired individual phases and operated in a temperature range from ambient temperature up to 400°C. Pressures from atmospheric pressure up to 60 bar(a) can be achieved.
