A dewar assembly suitable for use on the Farrand Mark I spectrofluorometer and similar instruments not normally equipped with a conventional dewar-type cryostat is described. The assembly is simple to construct and will accept either conventional round quartz dewars or square quartz dewars. A simple dewar arrangement has been developed to use on the Farrand Mark I spectrofluorometer. The dewar method makes rapid low temperature fluorescence and phosphoresence measurements possible. Rapid low temperature polarization measurements can be made with a square dewar modification.
