Pieces of laboratory equipment used in handling liquefied gases are described and factors influencing design discussed, with particular reference to liquefied air or oxygen, hydrogen and helium. Among the items described are storage vessels, vacuum pipe-lines, flow-control valves, level indicators and automatic level controllers. A method of obtaining liquid air by "conversion" from liquid oxygen is briefly described, and a general account given of the low temperature installation at the Clarendon Laboratory, Oxford.
