Determination of Melting Points

Abstract

THE determination of melting points is a simple but time-consuming process. Further, accuracy is limited by the observer's reading of a thermometer. The equipment described in this communication permits the accurate determination of melting and/or freezing points in about one-fourth the time required by conventional methods. The apparatus (Fig. 1) consists of three sections; a recorder which registers directly in degrees, a heating chamber taken from a conventional melting-point apparatus, and a test cell consisting of a sample tube and cover-thermowell assembly.
