AN APPARATUS FOR THE MEASUREMENT OF THE PROPERTIES OF CRITICAL MIXTURES AT LOW TEMPERATURE.

Abstract

An apparatus was constructed to serve as the basic unit for measurements of the properties of critical mixtures at low temperatures. It is designed to maintain measuring cells at temperatures constant to 0.0001K for long periods of time and in the range 77K to room temperature. The performance of a precision pressure gage, used in conjunction with this cryostat was also critically evaluated. Preliminary measurements of the vapor pressures of pure CF4 were performed.
