Anaerobic Facilities

Based in the Mineral Synthesis Laboratory we have various anaerobic facilities available within the Cohen group.

Anaerobic Chamber

The anaerobic chamber is a heavy duty, flexible PVC chamber with airlock access designed to minimise oxygen ingress.

There is a min. 0.5-2 ppm/min diffusion of oxygen through chamber surfaces. To keep the O2 level below detection limit (20 ppm) reusable palladium-coated alumina pellets-containing stainless steel mesh frames are mounted in front of recirculating fans. The palladium acts as a catalytic surface for the reduction of oxygen using the H2 from the chamber gas, and the alumina support absorbs the water formed by the reaction.  Additionally, a bowl of silica crystals is placed into the chamber to keep humidity low (20%).
