Summary

A simple and relatively inexpensive laboratory-scale method for simultaneously producing 36 different atmospheres for controlled atmosphere experiments is described. Capillary bore glass tubing (15-50 millimeters long; 0.1-0.8 millimeters internal diameter) is used to regulate gas flows, while gas compositions are varied by altering the length and internal diameter of the capillaries. Improved approaches to head pressure maintenance and calculation of capillary bore and length have provided a reliable and robust system which is easy to construct and maintain. Running costs are low when used with a nitrogen separator, as only bottled CO2 is required.
