CJC Labs design

We use a draft tube liquid air lock as a well proven method of maintaining anaerobic conditions while using a mechanical mixer. A minor disadvantage is that any back pressure in the system may force liquid up the draft tube, but this is more than compensated for by the simplicity of design, with no ‘gas tight’ bearing to fail. Along with the draft tube we use a catch pot mounted on the reactor lid  which allows the reactor to be used with our gas scrubbers and low-flow gas meter while maintaining a working volume of 0.6 L.

A special feature of our reactors is the double ‘o’-ring seal on the lid.  In engineering terms this is a highly reliable method of sealing a vessel, and our reactors have been shown to remain ‘leak proof’ over long periods.  The design also minimises any consumable requirements and we have found our reactors to operate leak-free over many cycles and years of operation.  

Up to 8 reactors can be maintained at a constant temperature in our low-maintenance water bath which has a bridge providing a fused DC voltage socket for each reactor, simplifying cable management and improving safety.
