Heat capacity (Cp) data for Apiezon N grease from 1 to 108 K are compared with previous results for this grease and for Apiezon T, with good agreement. Addenda results for a calorimeter in which Apiezon N grease is used for thermal contact between the tray and a sample suggest that a thin film of this grease has an appreciably larger Cp, below 4 K, than bulk grease. For high accuracy experiments using Apiezon N grease, care should be taken in the calculation of addenda Cp's from bare tray data and the Cp for bulk grease. During these measurements, Cp data for a high purity electron beam melted copper sample were found to be in excellent agreement from 1 to 30 K (±0.2%) with previous measurements [Holste, Cetas, and Swenson, Rev. Sci. Instrum. 43, 670 (1972)] on a different sample using a quite different calorimeter. © 1999 American Institute of Physics.
